I'd consider yourself lucky you got the free oil change! I'm not familiar with this company either. The info on the site looks good, but it's vague. They really provide no real technical info that I saw. Specifically what oil are they comparing it to? Tested by an independent lab? I'm sure it's good oil, but I won't be paying $9 a qt for it! If those numbers on shear and friction are correct and these numbers are compared to a good syn. oil, then you SHOULD see a performance improvement by cutting the oil friction almost in half. You tell us... what did you see???
