I just went to Checker/Kragen Auto Parts and saw this add for Duralube.
I was wondering if anyone has used any of these products in there cars, and if they really work, their websites say they do but u know how they are.
Duralube, Prolong, Motorkote, you know what I am talking about
Some of these products claim horsepower gain like motorkote, look at their site.
Has anyone ever used these? or do they work or is it a gimmick?
