and they went to 10k miles (oops moment for them...). Reputation for too much oil breakdown I guess.
Rule of thumb: Go with 15k oil changes if you add at least 2 quarts of oil as you go.
Go with 10k mile oil changes otherwise.
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...
you have it backwards but with same reasoning
. maintenance is included with new cars which coincided with the original bump up to 15k miles. since bmw was paying for it they did less frequent changes.
