i know engines are supposed to consume a bit of oil over time. but lately, my M20 seems to be consuming a lot. today it needed a quart.
its last oil change was 1200 miles ago. before this last oil change, it needed two quarts in the 3k miles between oil changes. there is no leaking or smoking of any sort. but im gonna pull the plugs tomorrow and see how they look. hope the rings and gasket are ok.
in my last E30 i would need a quart between oil changes, but that was just before oil change time, and that engine had a leak. so what is going on here?
i guess i do drive it particularly hard. my bentley says that BMW consideres it excessive if it needs a quart every 390 miles. above that, its fine.
thoughts or ideas?
