Never heard of it..

i highly recommend it my buddy put it in his loud zx3 and it idles better runs cooler and it idles more quietly and gives you some ponyies back and you will notice a difference in like 20 miles better gas mileage when you add to oil
and gas

Dustin- where are you running a V4? Focus engines are inline engines.

MMO: I typically use this in the first oil change when I get a new-used vehicle. I don't use it in fuel on gasoline engines. It does do marvelous wonders for diesels in fuel though. If you find somewhere that sells by the case you can save a good bit.

I'll tell you another funny thing. Go look at Amsoil's friction tests. Look how high Havoline scores.

I meant 4 four cylinders

Too much of a mystery for me we need the duke boys.
