I got tired or reading everyone's claims,listening to everyone's opinion and all the "quote,this oil is better than that oil".I had heard a lot of good things about Brad Penn Grade 1 Racing oil compared to a lot of others.I have been using it for 2yrs,it is actually the old Kendall GT 1.Go to the Brad Penn website and read the history.In December I had a few more guys that started the same thing all over again,its junk,this oil is better than that oil etc with nothing but an opinion to back it up.At that time I deceided to spend a couple bucks and get the real facts.Here is an unbiased oil analysis from Stavley Services in Kansas City.Should answer a lot of questions.Now,I would like to see someone else step up and do the same with some of the other brands.Would put an end to the guessing.
