BMW Revises 2014+ MY Oil change to 10k interval

by Bimmerfest.com Member - namelessman on July 24, 2013, 12:49 pm
FYI, a post at another enthusiast forum shows a memo from BMW(Attachment 5 to SI B000113) indicating the new 2014 CBS intervals for all vehicles. I wonder if on the next oil change the dealer will reprogram 2012/2013 with the new intervals. Any thoughts on this?

I had a 2002 X5 3.0 and that was 10K miles. So was my 2009 330XI. What has changed?

MY 2012 and 2013 F30 CBS is programmed to 15K/24 months, I believe the same is true for MY 2011 onwards F10, not sure about other models.

Personally, I think that is stretching it. I wonder if it was a decision based on the increased cost of free service for 4Yrs/50K miles versus a technical decision?

Yes, that's my experience.

When I got my 2013 F30, it indicated the next service would be in 15k miles. I took it in for its indicated oil change at 15k miles, and when I got it back it estimated the next service to be in 10k miles. I'm at 19k right now, and it's saying 6k miles. The service advisor didn't mention any updates to my car's software (and I didn't ask) so I don't know if this is the result of a reprogram, or if the car came programmed that way from the factory.

For what it's worth, the 2014 F30 Ordering Guide for the US still indicates a 15k mile oil change interval.

Thanks for the info, I will make sure the dealer does the same in my upcoming oil change.

When I had my car in for the dealer to recode the ASS, I mentioned to the service rep that I wanted the oil changed at 1200 because I'm and old fart and strongly believe in changing the oil after break in.

Of course, he got a pained look on his face and went through the usual "BMW recommends 14k miles for the first oil change . . . . " blah blah blah. Then he said something curious, to wait until about 2,500 miles because BMW oil has a additive for beak in. ???

In any event, I'll be curious to see if they reset the service duration, lowering it to 10k miles.

doesn't the computer measure oil quality and adjust on the new cars?

i've got under 7000 miles on my car and it says i need a service in 3500 or so...

Very interesting! Do you recall what it was indicating when you picked it up from the dealer? (And has it every been in for any sort of service?) I wonder if it said 10k miles right away, of if your driving pattern is particularly harsh on oil.
Saintor commented:
July 24, 2013, 3:48 pm

There was nothing wrong with 2 yrs / 15000 miles. They just need to improve their service income.

However I agree with their 60K spark plugs change rather than 100K. I had problems with mines (3 events, 2SP and 1 coil) just past 60K. I finally changed all SP.
Dave 20T commented:
July 24, 2013, 3:49 pm

Saab went from 15k mi. to 10k in 2006. Their excuse was the oil is still good but cars needed inspection for wear and damage sooner, hence 10k.

I have a 2011 e92 when I got in 2011 the interval said 15k after driving it showed me that I needed to go get oil change at 9100 miles.

Sounds like your driving style was harsh on oil. Lots of short trips perhaps, where the engine doesn't spend much time fully warmed up?

Most of my first 15k miles was spent driving 45 miles twice a weekday - a significant amount of time spent fully warmed up, cruising at highway speeds, in mild Texas winter weather.

I believe that 15,000 is just the starting point for the condition based service (CBS). Depending on your driving style that can move up or down. For example, my 2012 335i said 15,000 when I bought it, but now with 17,000 miles on it is showing service due in 400 miles... so it would be at 17,400 when finally showing a oil change due.

I suspect the CBS moved the interval out due to the fact much of my mileage was long distance freeway miles.

I had the annual, low-mileage change done in April, but this does not change the CBS mileage.

i know at one point it said 12000 or 13000 more miles. so the total amount has decreased since i've owned my car. and well i drive my car a little more aggressively than like some random older lady so i just assumed it adjusted to driving style and could sense it in the oil.

i mean new hondas i know have a gauge that tells you your remaining oil quality or something like that so i know that technology is out there.

While the referenced BMW memo (http://www.f30post.com/forums/showthread.php?t=868291 specifically states 2014 models produced as of July 2013, this may only be describing a change in production for new vehicles, not addressing a revision for previously produced vehicles which could be covered by a separate service bulletin directing dealers to recode the CBS basis as existing vehicles are brought in for service. That would make sense as how could BMW defend continuing a 15K/24 month CBS basis for the F30's manufactured prior to July 2013 while changing to a 10K/12 month basis for cars produced after?

Maybe too optimistic. BMW is likely to keep the 15k interval for earlier cars. Saab decreased the interval back in 2006. They did not retroactively change it for 2005 cars. Saab also had free maintenance in the US.

Looks like pre-July 2013 engines have nothing to worry about, but new units are not a durable.

All that means is that people should have been changing the oil sooner on all BMW engines, including those produced before 2014, but BMW doesn't want to include free oil changes as often for those as well.

not sure about that 15k interval. Mine is July 2012 built. Message came up at roughly 11K. I had an oil change this week.

It depends on how you drive and driving conditions as to when the sensor will display.

I hope your car is a lease if you're waiting 11,000 miles to change the oil.

Umm, I think you have reversed your logic. Pre-July 2013 models have been shafted with lower durability due to improperly infrequent maintenance and fewer pre-paid oil changes.

I can't believe it took BMW so many years to figure out their turbo engines couldn't do the 15k mile stretches. I'm guessing it's actually causing more problems during the CPO period in addition to reducing service income during the 50-100k mile stretch.

It is a lease. I would never do this to a car i owned. I drive moderately most of the time, but a lot of stop and go traffic, commuting from brooklyn to manhattan.

A number of criteria go into the recommendation to change oil - capacitance a major determining factor.

I really don't think so - there's been no problem with the oil change interval and the downside risk of not correcting pre-July 2013 recommendations, if a problem, is huge.

To wit: something's changed in the manufacture of BMW engines, as of this month.

Anyone gotta line on that?

That's what it is on our 2012 X5 3.5 (same 3L I6 turbo as the 335i). We do about 12k/yr, so we do a weird 12/3/12/3 interval schedule. Was the same thing with our 2002 X5 3.0 too (non-turbo 3.0L engine).

Two years sounds like quite a long time to go between changes, imho, given that low-mileage is usually correlated with a heavy cycle (i.e. short trips).

Really? Let me be clear: the first mass-produced BMW twin turbo engines are just getting to the end of their CPO lifespan now (many more to come, as well as single turbo).

So BMW is just now getting to experience the warranty related costs of the 15k oil span introduced on N/A engines and kept on turbo engines. Now BMW is pretty much all turbo.

You think they changed something in the engine - mid-cycle mind you - that would not change specs at all but reduces oil life by 33% all the sudden?

No: It's because of warranty work and a desire to drive up service income, plain and simple.

The 15k oil interval has been proven to be a terrible idea on BMW's direct injected turbos for 6 years now. The chicken has come home.

namelessman commented:

I wonder if the oil condition/level sensor is changed in MY 2014+ that requires shortened oil change interval. Given service is a big part of AVP bonuses, I would think dealerships definitely welcome the new change.

Fear of the unknown. Certain to provide peace o'mind, there's little downside.

Manufacturers OTOH are motivated to minimize environmental impact. So, for BMW to reduce the oil change interval is big stuff!

The basic warranty is 4 years or 50K miles, they should just go with service every 1 year or 12.5K miles or whichever comes first.

The basic warranty is 4 years or 50K miles, they should just go with service every 1 year or 12.5K miles or whichever comes first.
Back when I cared, I used to change the oil in my E46 330i every 6 months / 6k miles, when BMW's recommendation was 12 months / 12k (or thereabouts). Back then, around 2002-ish, there was the same hyperbole with people saying, "OMG every 3k or you suck." Or "OMG every 6k or you suck".

I did an oil analysis with Blackstone and it came back fine. So the next time I went to 12 months / 12k, and that one also came back fine. The Blackstone report actually had a chiding tone in the summary, something like, "despite the long interval, the oil is suitable for continued usage".

So ever since then I've just done a 12 months / 12k cycle. My E53 went 10 years and 100k miles with no problems. My E46 is now 11 years and 115k miles with no problems. My E46 actually burns less oil than my newish 2012 X5 35i. The X5 takes a quart every 6k or so. The E46 with 115k maybe burns 1/2 quart between the 12k changes.

I have a 2014 335i sitting in Bremerhaven waiting for a ship. I decoded the VIN here and get the below info 8KLA for oil change intervals. So I suppose this is confirmation of the 10K miles (~15,000KM) interval for 2014 models.



I bet service advisors are thrilled just not to have to try and explain the intervals and the whole "low mileage annual oil change" deal any longer. This makes it all very simple.

BMW's spec for oil usage is really, really tolerant. You'd practically have to be leaving an oil trail down the highway for them to take a warranty claim on it.

In any case, one quart between indicated changes is pretty common for the N55 in the X5. Dunno about the F30 application though.

Thank you for your actual scientific analysis of oil and being reasonable - old habits die hard and people spread too much FUD on online forums.
Dave 20T commented:
July 28, 2013, 3:28 pm

When a car goes out of warranty, I tend to like to postpone maintenance all winter. As a result, I tend to change the oil either yearly or every 6 month. A 9 month interval is undesirable since an oil change would be in the middle of winter eventually. In reality, it becomes an oil change every 6 months, except if the car has low mileage, like 8,000 mi per year or less.

Anyone who owns a BMW and used the CBS as a guide and waited 15k miles for an oil service would be a fool if they had any intention for keeping the car long term. This new guidance is long overdue and should have been provided with the fisrt turbo reintroduction N54 engine for the 07' MY.

Elk, the answer is diffuse since it's across the n54 and n55.

Google n54 or n55 15k oil change UOA results, fuel dilution, engine deposits, etc.

There are several issues that emerge:

- The turbos, which are quality mitsubishi units, appear to wear out by 90-120k in the n54
- Cylinder wall scoring has been noted in a number of n54 teardowns
- The engines themselves tend to coke up with oil ventiled from the crankcase back into the intake track. This appears to be worst on engines running oil the longest, because the oil breaks down quickly when it's in vapor form.

Thank god. I think it is about time they changed that to 10K. I think it was more to cut down the cost of free maintenance expense for them for first 50K miles.

I think this is the step in right direction. Because many had reported metal shavings in the oil at those intervals.

I think the spark plug interval for all the turbo inline-6 engines needs to be dropped to 45K miles. I had misfires right around 60K and many have reported as early as 45K miles. At least one spark plug change should be covered by the free maintenance.

When i first received the car on 7/1 (328xi) it said next oil change in 14000 miles 6/14. Then after a couple hundred miles it did change to 13000 miles.

Care to have a source here? I haven't seen the least problem for people following the procedure with the proper oil (LL-01). This interval was in force since 1998-1999 and there was no more oil-related engine problems.

My last oil change was in June... 2012.

Like yourself I mostly went with car based sensor for oil changes for a long time in past.

Except recently with my E92 335i. I have gone in for early oil changes and my SA who is great took care of it for me under low mileage rule of some sort.

As for the issues with long term oil changes. It has been reported by a lot of folks over years on various BMW forums. In fact most BMW tech will also not recommend 15K intervals. But more like 7.5K intervals.

The reason being sludge built up and even metal shavings. Most BMW tech will tell you that the small ports in the Vanos unit that change cam timing with oil pressure can and will clog up under these new service intervals.

Here is a pdf by the famous BMW roundel magazine regarding their recommendation on oil change intervals for BMW's.

http://www.google.com/url?sa=t&rct=j...ZVxMlIv-HqrFxw


Also, many BMW service places including even DINAN BMW authorized guys don't recommend waiting until 15K miles.


Below is an oil analysis by a BMW owner. Go to post #11 down in the thread.

Anyways, my opinion on this matter is it is better to be safe then sorry. So I will try to keep up with 8K mile oil changes as miles are pilling up on my E92 and it will soon be out of warranty.

Well the metal shavings link you provide is unlikely to be related to the oil change intervals. It was probably not well cleaned from the plant.

Oil analysis mean little ... unless one can prove that THIS level of contamination has worse consequence than THAT one. In the meantime, in close to 15 years we haven't seen real oil-related issues on BMW engines for people following the right instructions.

I wanted to ask you if you don't mind. When you say "15 years we haven't seen real oil-related issues ". Are you a tech or own a service shop or work for dealership. Just trying to understand the back ground behind that statement. Most independent and even some BMW tech will tell you to go for early oil changes around 7.5K miles to increase longevity of engine.

As an owner it all depends on how you look at it. If one plans on keeping a car well past 100K miles or if a car is modified. It would be good to go with 7.5 k mile interval. If one plans on changing cars every 4 years and seldom get over 100K then I guess 15K is fine.

On a side note I also have noticed that my N54 twin turbo has greater appetite for oil then 4.4 liter V8 and 2.5 liter inline-6 M54. I knew the M engines were oil thirsty due to their high performance nature. But I guess N54 is also very oil hungry.

That's the point. You can even double or triple that. Personally I know that I won't have my car past 7-8 years. Yet if I would keep it, I trust its powertrain to reach 12 years / 300K miles, like most modern engines are able to do.

Why to pay for something that you won't benefit? It makes no sense.

No I have no formal car-related involvement, just your basic mechanical engineer background.

15 years is a LOT of cars, yet in this era of internet you have to work hard and push the envelope to find any BMW that developed any oil-related problem (with procedure followed).

When my wife took her then-new 2012 X5 35i in for service with around 3k miles, I told her get an oil change. The SA, who we've been using for about 15 years, said it didn't need one and sent her home without it.

Then around 6k miles she went in for another service (sticking door locks or some such thing). I told her again to get an oil change and let the SA know we'd pay for it. So that morning my phone rings and it's the SA. He says that in all his time at that dealership, they've never seen any engine issues from following BMW's service intervals. And if I really, really wanted to pay for an oil change he'd take my money, but he really didn't think it was necessary.

Just throwing that data point out there since you asked about feedback from people that work at dealerships; people can ignore it if they like as anecdotal. On another note, the turbo engine (N55) does seem to burn more oil than the non-turbo I6's that I've owned.
Kayani_1 commented:

That is off course unless you ignore all the BMW independent service shops or techs that have pictures to prove the damage of sludge etc.

Most people that drive BMW's are the ones who keep them for 4 years at most and never reach over 100K miles. Majority of the time it is the second or third owner who has to deal with the issues of 15K mile oil services.

At that point people ignore their issues as that model has been well past its prime anyways and masses have lost interest in it to keep up to date. Also, people can easily point fingers at first owners for lack of proper upkeep and maintenance.

Either way I have had no serious issues due to 15K mile service intervals so far with my prior BMW's. Then again I have not had any over 106K or well past 5 years. My plans with this E92 of mine is slightly different. Thus, I am planning on keeping the oil intervals closer to 10K or less if I can help.

My little idea in these anecdotal cases is that the BMW maintenance procedure was simply not followed.

Long term is beyond the warranty period.

I think that issues from these long oil changes are coming home to roost and the manufacturers are worrying about warranty claims. I changed my oil initially in my 07 E90/328 at 3K miles and then again every 7 or 8K after that. When the dealer changed the oil and reset the maintenance minder, it said that I had 19K before the next change was due. Of course, I did not go that long, but no doubt some would, especially those leasing. I think 10K or one year max make much more sense for most people, especially those planning to keep their cars. Mine now has 105K on it and has been bullet proof so far.

I am still driving my original owned 2006 330xi (N52) at 148k mostly highway miles via CBS 15k to 18k miles oil change interval and it's still on its original ATF, original water pump/sensors, original AC refrigerant, original power steering fluid.
I had to change battery, low beam bulbs, parking bulb, shocks at 140k miles.
2 sets of coils at around 60k intervals, 1 set of plugs and differential fluid at 100k.
standard brake/coolant flush schedule.

It's not the turbo engine but people said the same about 7.5k interval changes for a long time, not just BMW but across different makes.... this is the longest time I've kept any car because it ran so well, averaging 25.5mph.
I also have a newer X3 using CBS.

Makes sense to me!

Here's an interesting thought. Some people on here think that the car can sense the condition of the oil and will know when to change it. (I don't. I think the computer does that by making observations on driver inputs.) So, since you have changed the oil and did not reset the sensor (I always reset, myself), if the car can sense the condition of the oil, it must have sensed that your oil suddenly got a lot better when you changed it and, concomitantly, increased the interval to the next oil change. Did yours do that?

Thanks,

I recall reading on this forum that the latest oil sensor measures conductivity(?) of the oil and deduces the oil quality from that, don't know much about the truth/science behind that. On my old E39 it did go with fuel consumption, or exactly 2375 liters per reset.

While I tend to agree with you and change my oil more often than recommended, there is a gent (goes by the name of Flyingman) over on the Bimmerfest Diesel Enthusiasts Forum who has been having his oil tested every 3500 miles to see whether the analysis reveals any need to change sooner. He posted his latest test this week and concluded that he can go another 3500 miles to the end of the recommended period with the oil that is in the car. While I will still change mine early (being really old school), his is the most considered (i.e. non-anecdotal) basis I have seen for following the recommendations.

What is the oil capacity of the F30 4 cylinder engines?

After 14 years of ownership of 2 BMW 6 cylinder engines, I am fine with 1 yr / 10-12k intervals - no issues and examination at 110k of my M52TU valves showed a pristine lookin engine.

Turbos and less oil capacity would probably require more frequent changes than the older NA 6 Cylinders engines.

Sports package cold weather package it's loaded completely , I'm curious to get some input from some of the new and veteran bmw owners on what should I do as far as modifications to my car both visually and under the hood? Immediately I'm changing the xenon lights to HID and changing the Halos for an HID pair as well. I know alot of people go silver and black but I'd like to try something else different more unique. Any suggestions guys and gals ? Thanks for reading hope to hear back soon

My new car was showing 10K when I picked it up. Yesterday, at 750 miles, it started showing 9K.

Does it go down 1000 miles at a time? On my E46, it went down 25 miles at a time.

Am I driving it badly given that service interval dropped 1000 miles with just 750 driven miles? Most of my trips have been around town with lots of stopping at traffic lights, but there has also been a decent amount of highway driving.

My oil change interval with option 8KC(2-yr/15k) started at 15k and quickly adjusted to 14k and then 13k(it settled at 12.5k), my guess is on 8KL(1-yr/10k) mine would end to up be 8k or so.

BTW, I got my low-mileage oil change last week but the dealer didn't reset my CBS nor reprogram to 8KL, they said there is no outstanding SIB on it for MY12 nor MY13. The SA did say for 8KL, the spark plug interval is still 60K miles, so for MY14 it would be 6 oil changes, while for MY12 and MY13 it would be 4.

For those who successfully got dealer to recode from 8KC to 8KL, can you please share the SIB? Thanks.

Is there still a maximum mileage for the annual change? There's no way I'm going to hit the CBS requirement before the 1-year anniversary. I drive maybe 7,000 miles a year.

Edit: At one time they said you couldn't get a free annual change if you exceeded 6,000 miles. Is that still around?
namelessman commented:
October 28, 2013, 11:21 am

I believe other posters mentioned the CBS can go above 15k dependent on driving patterns(e.g. all freeway cruising). The SA didn't mention a 6k minimum requirement, he wrote "perform annual oil change" on the invoice, so it should be a standard chargeable item to BMW.

I recently took our '13 N20 F30 in for service with the indicator saying 2100 miles to service as we were about to take a road trip of ~4000 miles (and didn't want to exceed the service mileage by a couple thousand miles). When new, the CBS indicator said 15K miles. At the time I took the car in it had ~13K miles and the indicator was displaying 2100 miles to service, consistent with the initial 15K indication.

When I arrived, the SA 'read' my fob and indicated I was 51 miles shy of the early limit BMW imposes to provide the service, that limit being 2000 miles. I found this interesting from a couple of standpoints; 1) it's the first time I've heard of a 2000 mile early limit and, 2) he was able to 'read' the mileage to the mile where the in car display had said 2100 miles to service for the last 300 to 500 miles, apparently being a low resolution indication (don't know why the SA I'd made the appointment with the previous week did not mention this mileage limit as I'd explained it was early).

So, I drove home and came back that afternoon, having added more than the requisite miles needed. When returned, the CBS indicator displayed 12K miles to service, so it appears the base mileage was revised to 12K miles when they reset the CBS.

On a related note, during this visit the dealer indicated that in addition to the mileage, they want the car brought in for service annually. This was surprising as the CBS indicator has always displayed a mileage or two years from the in service date. And, when reset during the service, it now displays 12K miles or 2 years from the service date. I've checked the manual and, unless I've missed it, not only can I not find anywhere an owner is told of this annual service (regardless of mileage) and, indeed, the CBS display indicates semi-annually.

That's interesting - my indicator shows I need service in either 9k miles (I have about 3k miles on it) or May 2015 (just shy of 2 yrs from delivery date in June 2013). I will surpass the remaining 9k long before May 2015, but it's hard to believe they would really only want to service the car every 2 years if kept to low mileage...
Dave 20T commented:

I used to think that I wanted my car reprogrammed to reflect the 10k oil change interval. Now, I don't care too much. I found a place that charges $10 to rent a lift (Self Serve Garage, Kent, south of Seattle). With a lift, an oil change is very simple. The difference with a lower interval might only be one free oil change.

Calculations:
free oil change - 10k versus 15k
2nd oil change - 20k versus 30k
3rd oil change - 30k versus 45k
4th oil change - 40k versus 4 years of free service ends.

high mileage example:
5 oil changes, cutting it very close as free service ends at 50,000 miles or 4 years. Compares to 3 oil changes at a 15k interval

low mileage example:
8k mi per year: 3 oil changes versus 2 with the 15 k interval

very low mileage example:
yearly oil change interval applies

I wonder what this does to Inspection I/II...

Normal it is oil service -> inspection I -> oil service -> inspection II...which means the first inspection II happens at 60K. Now with the 10K service interval, where do the inspections come in? Instead of 2nd, 4th, etc., would be 3rd, 6th, and so on? Or are those intervals reduced as well?

It is not as straightforward as pre-CBS days, each service(oil change, inspection) have its own criteria, but for mine with 8KC it seems the vehicle inspection falls on the 2nd CBS oil change(NOT annual oil change). My guess is inspection is every 30k, so on 8KL it would be every 3rd CBS oil change, although some MY14 F30 owners with 8KL may need to confirm that.

My E60 manual did say to bring it in at least once a year regardless of the CBS but my F30 does not. That's why I was wondering if the service was still offered. Good to hear it is.

They'll probably just do two oil services between inspections. That's how it used to be back when I had my E36.

I drive moderately, not pedal-to-the-metal but I use the 4cy turbo as it was meant to be. I changed the oil at 7280 miles just because. Nothing was reset. The CBS indicated that I change the oil at 14720. I did. Comments weaselboy? Think your oil was changed prior to you owning the vehicle?? I am not certain the CBS is an oil change genie. I think it's a very simple indicator that is based loosely on mileage with no consideration of time or driving style.

I suspect the CBS moved the interval out due to the fact much of my mileage was long distance freeway miles.

I had the annual, low-mileage change done in April, but this does not change the CBS mileage.

I bought the car new, so no oil changes were ever done before.

I have read speculation the CBS is based more on fuel consumed. So for example, if you drive like a maniac you will consume more fuel per mile driven than if you baby the car.

You can change your oil once a week and that will not impact when the CBS calls for a change.

My car had the first CBS oil change done in Feb. Today I checked the OBD->CBS item, it lists the following:

22.01 km/year short term 12000
22.02 service call stats 0
22.03 limit, time 1 mth
22.04 limit, distance 2000km

My interpretation of these is that the car now has 10000 miles/year oil change interval, and the distance limit is now 1250 miles(it used to be 2000 miles), however there is no clear indication that the car has been updated to 8KL 10k miles/12 months(the service visit invoice does not say anything). Also, it is odd that there is no additional info on other CBS items(e.g. brake conditions) under 22.xx. I can't quite remember seeing 22.xx OBD entries before the CBS oil change, so it is unclear if there is a recoding of the oil change interval or not.

Hi,

This all seems a little bizarre. I have a european F12. It currently has 2500 miles on it and the CBS says it needs oil in another 19000!

21500 miles seems significantly different to the US based cars. I cannot understand why that would be.

Regards

I read that European BMW's CBS is set for 30,000 km, which is about 18,000 mi. In another brand, their monitors originally showed a lot of life left, but rapidly went down as the car approaches the servicing mileage.

After 14 years of ownership of 2 BMW 6 cylinder engines, I am fine with 1 yr / 10-12k intervals - no issues and examination at 110k of my M52TU valves showed a pristine lookin engine.

Turbos and less oil capacity would probably require more frequent changes than the older NA 6 Cylinders engines.
An oil change takes 5 qt. The total capacity might be 5.5-6 qt.

Is yours a gasoline engine? Some festers did comment that Euro gasoline has lower sulfur content than US gasoline (and sulfur can quicken engine oil degradation).

Hi,

No 640d. Not sure if the Sulphur issue is with the diesel too, but it may be the reason.

The Euro V fuel standard(gasoline and diesel)should be 10 ppm of sulfur. The EPA adapts ultra low sulfur standard on diesel(15 ppm, used to be 500 ppm), but US gasoline is still around 30 ppm(and the EPA is planning to lower that also to 10 ppm).

European models have much longer oil change intervals than North American models. Probably due to our higher sulfur content in the gas. I saw a thread on a European forum where they were talking about the American "oil change culture", which I admit is kind of silly.

They are bad mouthing Americans. Many Americans follow long oil change intervals. Sometimes 3-4 years. I think the percentage of Americans changing oil every 5,000 miles or less is small. Same with Canadians.

Frequent oil changes are pretty deeply embedded in our car culture. I think we've been in the process of a long slow change, but it's still underway.

Had my 2012 328i serviced yesterday and the CBS says next due at 13k miles. So it's right in between 10k and 15k at this moment. Hoping it drops rapidly toward 10k as I drive, however I hardly come close to flogging the engine so I'm not sure that will happen.

Your mpg @ 34+ is amazing!

Why do you car what the CBS says? Just follow what it says.

Yup, I just follow the CBS always. I'm not part of the change-the-oil-every-5k-miles crowd. This was just data for those who were wondering whether the pre-MY 2014 vehicles got the mileage interval reduced to 10k from 15k.

I'm impressed with the mpg too! This car's been a great performer while giving very impressive mpg numbers.

I have 1300 miles so far and have averaged 26 mpg, but I am not trying for best mpg. I am often in 4th or 5th gear while the car's suggestion is to shift into 6th. My previous car's long term average was about 28 mpg.

But 34+ mpg is out of the world. It's at the highway mpg rating and if you're getting that for combined driving it's really amazing!

That's combined, but predominantly highway. When I drive around town it drops down to the high 20s, which is still pretty good. You can see on my Fuelly page the % driven city for each fill up. What's really impressive is that on the highway I often drive at 80 mph (speed limit is 75 here) and still see those numbers. This is mostly in Comfort mode btw.
