Exactly what the title says. My BMW Burns a quart in between it's 15k intervals. Does that mean I can go longer because fresh oil is added?

I wouldn't go longer than 15k miles intervals. I'd assume BMW already assumes you'll be adding make up oil.

It probably does.

But I would not do a 15k mile oil change in a BMW.

More than a few BMW engines have serious issues amd I think over long OCI is part of the problem.

I wouldn't. I had to cut back my Grandma's oci to 10k because of varnish causing problems with the VANOS solenoid on her 325.

If its only 1 quart, thats not much. No extension. Now, if you were putting in 3 quarts, then 18k wouldn't be out of the question in my opinion. Adding oil does replenish detergents, anti-oxidants, ZDDP, dispersants, etc., so yeah. Its a matter of how much.

Rule of thumb: Go with 15k oil changes if you add at least 2 quarts of oil as you go.

With a UOA backing it up, showing the oil is still good, no reason not to.

At most 100 miles per 100ml is all I could see tops. Your adding clean oil but the rest is already dirty so therotically yes but not by large margins of oci intervals

While I would not go longer in a BMW without a subsequent UOA (and even then, why?), I can tell you based on my experience in my 2010 FX4 that adding even a half a quart increases the TBN and thus increases the overall potential OCI.

Good advice. The OLM on my wife's 2011 328i would have had us changing the oil every 15,000 to 18,000 miles (pure insanity in my view). Her new 2017 330i OLM would have us change it every 10,000 miles (still way too many miles for a DI Turbo IMO). Two different BMW dealer service departments told me the longer OCIs in older cars were, in fact, causing major engine issues thus the change. I change the oil in her cars every 6 months or 5,000 miles. Electronic oil measurements on both cars always show 100% and engines function flawlessly.

Interesting turn of events... just when all manufacturers are INCREASING OCI even with Di and Turbo high strung 1.5L engines, etc, BMW is going BACKWARDS and DECREASING the OCIs just as oils have reached what is basically a very high level of capability in regards to Lube performance. Hmmmmm....

The real question is, did they do it for better engine protection or did the maintenance department guy have a little chat with the finance department guy at the water cooler and pointed out the extra $,$$$ they could be making with more frequent OCIs??? Lol.

Ah for the Love of Money...

My car is a 2012, technically that bulletin doesn't apply to it
The long intervals actually don't scare me, considering most oils would easily be up to the task - even non-approved ones
Car has been running like a top, 95k and counting

Just curious on other people's input
I wouldn't deliberately extend the interval, but it would give me some more peace of mind if I happen to run over or am late to change it

I really don't think the 15k interval is all that bad. Let's be honest, there are plenty of BMW drivers out there that don't know the where the hood release is, let alone maintenance intervals. And then there are plenty of people who will see warning lights and service overdue reminders but keep driving anyway. BMW would not give a 15k interval without some safety margin built in. ALL oil changes have safety margin built in. Otherwise we're all driving around in time bombs apparently...
