Annual oil change?

Does BMW cover an oil change every year even if I don't reach the 15k miles required? They didn't change the oil when I bought the car CPO and the SA from the dealer I bought it from said it was changed last May. Weirdly enough, when I bought the car in January the computer said I still had 15k miles till the next oil change.

Well, it's now May and I have to take my car in for some other things anyway but the car says it's not due until May of 2015?!

To answer your first question, yes. BMW owes you an annual low mileage oil change while you're still on the 4 year covered maintenance regardless of what the cbs computer says.

The rest of your post confused me though. So you bought the car 8 months after the last oil change and the computer was still saying 15k miles until oil service was due? Sounds weird. Was it sitting on the lot for a few months? Did they change oil as part of the CPO reconditioning and not note it in the records?

As far as the car saying "not due until may of 2015, " you aren't referring to oil change are you? As you said above, oil change due is measured in miles to go based on how you drive not time.

Bottom line is if you're still under the "free" maintenance and the last oil change was indeed done last may, they should owe you an oil change.

The 'once a year' is calculated from the date of the last change, not the date on which you purchased your car.
For example, my 'once a year' occurred in April 2014, although I purchased the car (and although the dealer had done a CPO pre-delivery oil change!) before I took delivery of the car in December.

I'm not sure this applies to post-2009 cars. IIRC, they went to an "every two years" OCI in 2010, if you hadn't timed out on the CBS.

Additionally, it's not always 15000 niles by the computer. Mine tends to think it wants the changes every 20,000 - 22,000 miles, although I do them every 7500.

Interesting, I hadn't heard about that. I wonder on what reason they based the increased interval? (besides the obvious one of bmw cheaping out to save costs) IIRC, the N55 was implemented in 09, so that's not the reason for '10 and on change. Obviously the N52 was still the same between 09 and '10. Any idea?

No, the car didn't sit on the lot. I picked up the car as soon as they got it in, the dealer barely had enough time to get it detailed. The CBS currently says about 10k miles for 05/2015 for the next oil change. I asked the dealer and they said they didnt change the oil during the CPO process. (They also didn't change the wiper blades )

Either the last owner didn't drive much in the last year because of mileage restrictions or something is "off".

Maybe lots of highway miles? And what's up with the wiper blades? Talk about cheaping out. indeed.

I bought my '11 335xi last March and waited until a few weeks ago to bring it in for the annual oil change that's covered under the CPO. Actually, the manager also had the brake fluid flushed/changed along w/ a couple of other goodies that wasn't expected or recommended in the service log.

As for the timing/mileage of when the car tells me to change, I'm changing at least every year even though I don't drive an astronomical amount (@6600 -7000).

Seems my memory isn't what it used to be. They dumped time-based oil changes for all cars, not just post-2010, unless it's a garage queen. I likely wasn't paying much attention, as I put on 25k-30k a year or so.

SIB 01-04-10. An annual oil change is only done if you drive 6000 miles or less. Stones399 was likely close enough to the edge that the dealer didn't have a problem putting it through.

As to why, beats the hell out of me, Roy. The reason given in the SIB seems rather self-serving.

change it on your own, its not that expensive, and I would not rely on BMW service interval unless you are going to dump the car in a year, 7500 is the max I go before an oil change, you should see the gunk that builds up in these engines on youtube, it will cause a lot of issues with the VANOS system

What brand of oil and weight do I use?

You have THIS. There are three sensors in the unit - oil condition, oil level; temperature. Chip in base runs calc's; interfaces w/car's computer via digital bus. Being as you bought used, if were I, oil would be changed ASAP along with brake fluid flush. Mileage? If high, tranny fluid & filter replacement. Have a look at your coolant.

Battery check?

THIS and THAT, and what about Oil Filter and Valve Cover Gasket?

Hmmm....have you looked beneath?

And what about those solenoids?
I'm at 41k miles. I've checked coolant, looks fine. Brake flush was done in march under free maintenance. I've yet to do an oil change. I will do transmission done at 60k miles at an indy.

Should I trust the CBS when it comes to oil change, or should I just do it every 7500 miles? What would you do on your car Cal?

In spite of my mods, it's not my daily driver and after 5 years, Wifey drives it more than I.

So. I let the oil condition sensor decide.

Let me put it this way. By the time I hit 10,000 miles I had three oil changes. Then I went to 5000 mile intervals.
IMHO the average person should go with 7000 mile intervals on any BMW he owns and intends to keep for a long time.
Leased? 15K freebies for the life of the lease.

Frankly I think BMW's cbs algorithms are skewed on the side of leases, and factor in cost of free scheduled maintenance. I see a lot of 15K interval cars and I don't like the varnish or gunk I see under the filler when I do a change. Engines with 7K intervals are as shiny as the factory made them under the valve cover. To me, that's an indicator of many good things having to do with the VANOS controls, the rings, and the valve stems.
On the other hand I am hearing of 20,000 mile scheduled intervals being considered by some top marques...

I plan to drive this car until the wheels fall off. I will do the 7k interval.

20k intervals? Are we talking about Porsche? Would be interesting to see a Blackstone oil analysis after 20k miles.

Which is why I wouldn't take an off-lease BMW.

The CBS system skews even worse on mostly-highway-driven cars. If I was going with CBS intervals, I'd be changing every 20,000 - 22,000 miles, instead of the 7500 I actually use. And it sure is sparkly-looking in there when I open the oil fill cap.

Hey, did Ilse's intake ever get scoped? That's one part on mine that wasn't sparkly.

No, it was on the schedule for the following week and then the schedule fell apart. There's just been too much "Spring cleaning" needed around here since then and my Summer help doesn't start for two weeks.
I am really curious about the presence or absence of carbon build-up. I have a theory that long intervals promote the condition for a couple reasons. If my intake valves are all crud impacted I'll throw my theory out the window. But if the intake is clean, I'm going to say the reason is short oil change intervals. The scientific method, no, but good enough anecdotal evidence for me.

Man, if there's a difference between your 5k intervals and my 7.5k "Wow, is that cruddy!" situation, I'll be stunned. And also changing my oil 1/3 more often.

Yeah, I recall your 'cruddy' thread and said uh-oh to myself when I saw your intake valves. Anyway, I would never let facts stand between me and a good theory. I chalked your results up to very poor driving habits.


Actually, according to my theory your kind of driving should result in the best of all possible outcomes and I would have predicted clean intakes. Strike two!

Wait, there's a problem with "I just put gas in it and go!" ?

I so want to see someone Seafoam the intake on an N54. I also so want that person to not be me.


Edit: Hey, found one! Yeah, this looks to be the ticket!
