Thread: Oil catch can question.

whats wrong with burning oil? keeps everything rust free in the exhaust.

i mean, i get it if youre going through a quart in 1000 miles, but my subaru definitely goes through a quart each oil change.

Oil in the combustion chamber reduces octane while building up on intake and exhaust valves.

yeah. but a minimal amount of oil being burnt is never going to hurt.

I don't know how to quantify "a minimal" amount of oil. A catch-can does help out lots of motors though.
