How Much Oil Do you Use?

[Linus Toy]

One more I've heard of...excessive oil in the intake air (i.e. by leaking thru
the turbo seals) can reduce the effective octane of your fuel...perhaps less of
an issue with the Motronic and its (hopefully) fail-safe limp-home mode, but
years ago, one turbobrick (old style Volvo) owner reported losing an engine
this way.

I'm with Brett here--not good to ignore esp if you're chipped.
