I know you aren't following but just as a comment, your experience has no bearing whatsoever on the situation. It is actually what causes people to change their oil when it is not needed. Engines and oils have changed a lot over those 40 years. What was recommended back then is not applicable to today.

As a number of folks have said, people are free to change their oil as often as the wish for whatever reasons they use. I don't think anyone is arguing against that but rather making sure that the current, relevant information is out there.

So I do go by the maintenance indicator. 120k on my JGK and 24k on my 330. 185k on my TL when I sold it. Sample the oil and have it tested every 2-3 changes. Has always been a good report with life left in the oil. No engine issues. Always use full Synthetic of the correct spec, no short trips, towing or long traffic jams. Oils and engines have greatly improved over the last 20 yrs

That’s a mighty long and thorough explanation and reasoning for someone not giving a flying. :)

I've got a 2014 E550i in the shop getting a newly remanufactured long block and turbos because the lady that owned it ran it out to 37,000 miles without an oil change. Personally if I were to own one of these cars I would not run it past 7,500 miles on an oil change on full synthetic of the appropriate viscosity.

If you are worried about possible warranty issues, have BMW change it at the CBS intervals, which will meet warranty requirements. If the CBS intervals seem too long, then just add oil changes in between at intervals that make you more comfortable.

Also make a periodic electronic check of the oil level, since some folks have complained about oil usage on the M340i. Mine never shows a drop between oil changes, but leaks or other issues are always possible. On my F30 with a leaking oil filter cover I found that it displayed a low oil pressure message before it displayed a low oil message. Just the opposite of what I expected.

Low mileage here on 3 cars in the family of 2. Less than 6000 on one, less than 4000 on the second and less than 3000 on the third. They all get changed once a year. I would not go 15,000 miles. I am old enough to remember when changes were every 1,000. Newer oils are much better but why push your luck?

as Logicalapex is very correct, so this is my last post and also setting the thread to unfollow.

People, you all can do what you want or like, don't do an oil change ever, once a year, once a month, according to CBS ANYTHING
I really don't give a monkey's. Seriously. I don't. It's your car, your dime.

I have 40 years experience man and boy wrenching, on everything from Porsches to Ford's, that's owning and maintaining them.
So I would like to think I know what I'm talking about.

ENGINE oil is the life blood of your car, no 2 ways about it. The engine is the heart. I have followed "absolute" manual specs/manufacturer specs/dealer specs/
forum specs and club member specs for ALL of my cars.

The only absolute bullshit is BMW's 15k oil change, if you do that, you totally deserve to have your engine grenade, you should be riding around in a pedal car
and not a real car.

In the UK, for the Porsche (out of warranty) I followed 3k oil changes because a lot of club members and reliable techs advised.

You will find the minimum is 1 YEAR, even if your car is parked up doing shit, thats right every 1 year.

After seeing the shit coming out of my 1 series after I followed the actual CBS 15k change, scared the crap outta me the black sludge that came out.
Don't know about you,if I spend 35k on a car I'm going to look after it

I got in the habbit here of doing bi-yearly oil changes, because here we do seasonal tire changes so it made sense.
So for the last 10 years on ALL our cars we do twice yearly changes, I also opt to do a mid year filter change.

Recently my BRAND NEW 55k 2 series, get's the same treatment, I also now work about 6km's from home, so my yearly is around 5k,
I still follow the same model, and as it's under warrantee, I usually get the old yearly (BMW free reminder) and when I ever hit 15k, I get that as well
mind you I have only 11k on my car FROM NEW in 2 years, I've done 4 oil changes, BMW have done 2, I've done the diff change at 2.5k

Like I said, I only give my opinion and what I do, and that works for me, my engine is worth a couple of hundred bucks in oil changes.
my car starts first time everytime and runs like swiss watch and THAT's worth it for me.

Some people like to chat absolute crap and that's fine by me, if you decide what is acceptable for your car that's fine, but don'e winge and whine
when shit goes wrong. because "some guy on the internet said you can use mazola every 15k"

and I don't give a flying F, if people think I'm batshit crazy, I'm not driving some crappy Honduh or 15 year old POS dodge,
I'm driving the "Ultimate Driving Machine" or BMW for short, and my car is worth every penny and 55k spent is no short change.

Give that man a prize! he is right! ABSOLUTELY CORRECT! Change your oil and change it often it's your car/equiptment take care of it...BMW wishes you would buy a new car often!! so don't change your oil!

Remember BMW is in the business of selling new cars. They don't give a shit if your engine grenades after it's out of warranty. Their 15,000 mile oil change intervals will get it out of warranty, then it's YOUR problem. I have a 2006 X5 M54 with 271,000 miles on it. Change my oil every 5000 miles and use good quality synthetic oil, usually Liquimolly. I haven't had any issues with this engine that are in any way wear related. Over on Xoutpost there is a member there that has over 300,000 miles on his M54 engine and IIRC he uses the same interval I do. You go ahead and follow the BMW recommended interval and I'll follow mine. Let me know if you manage to get 270,000 or over 300,000 miles out of your engine.

Thank you for your post. 1000% agree with you. I change the oil/filter every 3500 miles or a minimum of three times a year. Use a high quality oil and OEM spec filter (like Mann). Good oil changes will save you thousands down the road. Thanks again.

100% I could not agree more and have the valve stem seals in an N62B48TU to prove it - meaning they are original, no smoke blow and oil and filter changes every 5K miles or less since new. Between BMW oil change recommendations and running the engines at 105C since the late 90's, you can create a ton of reliability and longevity by changing those two things.

My engine, the 1997 M52B28 E90 528i, was born in Munich and lived in - F in a mildnsouthern Mediterranean climate, until recently. She now is living her worst nightmare in Southwest Louisiana- a Sub-tropical climate. The Last oil change was France, March 22 at 39K km-- Synthetic 5w-30 is what her mechanic had been using. Approx 10k is what the factory recommends for that car.. I've put 8K km since then. I have 2 green bars left on oil health. I'm Ok with going down to 0 green bars (approx. 6,000 Miles) BUT for me, living in a Sub-Tropical climate- everyone here uses 40 wt on top end.30 wt is just too light. The mechanic I use goes with15w-40, but I'm fixing to change it using the Mobil 1 European car 0w-40 for year round--BTW-all these "special oils" with proprietary additives like Kubota, BMW, etc. etc. Yeah. Just use the AASI latest greatest approved oils and most likely your ride will be happy with the non factory.. Just sayin, check it out.

Sorry. Don't agree. Over the course of time, the additives that make the oil do all of the amazing things that it does, are depleted. 10K is too long. 15K is abusive. Again - your call.

Except all of the data shows you are wrong about that. Again, feel free to change it as often as you like but there is no technical/practical reason for doing it. We are talking about today's oil's and not those of yesteryear. ;)

Yes, check it out. Every Blackstone report we have seen on oil changed at the CBS recommended interval has been fine. Makes sense since the actual lifespan of today's synthetic oils is over 20k miles. Europe's oil change is close to that and they aren't having issues either.
