That sounds more like a BMW problem unless you were putting huge mileage on it. Lots of 90s vehicles on conventional oil would go over 300,000 miles without rep

That sounds more like a BMW problem unless you were putting huge mileage on it. Lots of 90s vehicles on conventional oil would go over 300,000 miles without replacing any major parts. Just alternators, plugs, and $10 sensors. Anything newer running on full synthetic is a total piece of shit if it isn't hitting 400-500,000 miles
