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?


Hey guys Don't use slick 50 the manufacturer
of slick 50 did not have enough scientific evidense to support their claim .I have read
article that slick 50 formulation when mix with regular oil have a tendency to cake in your engine
after a high spirited driving, and block oil passages on the Engine block and cylinder head. There was a lot of complain about it. I remember when they first marketed this product, it cost about $50 after they where question by the NHTSA now they are selling them for about $17.
