Great deal

Superfast post.
I've used this additive in several motorcycles and cars: they have all clocked up high mileage with no problems. I stripped a ducati engine with 125,000 miles and the bores and pistons had almost new tolerances.
Makes my porsche 911 run 2-5 degrees cooler too!
Great price too. Read full review...

Well worth using it

I have been using Slick 50 for years and the coating it leaves a smooth surface so the internal moving parts don't wear so much
