I've been using this stuff in my engines and I think it helps. My civic has 325,000mi and is still going strong (original un-rebuilt engine). Less throttle reqd. while cruising at fwy speeds.

I run it in my E30 M3 also but and uphill left right combination starved the oil pickup and spun the number 3 main bearing. So it won't prevent engine damage due to oil starvation, but it will make an otherwise rough engine run smoother and last longer.

BTW: I've tried Duralube and Slick 50 also in the civic, but only felt a difference with Prolong in the engine. Didn't try the tranny and diff.

I would stay away from putting it in the diff, as the diff should have a certain coeffient of friction, it may be too slick.

Any other opinions?
