As a dealer, one of my favorite things about Amsoil was their willingness to publish not only the test data but also the results in which they did not come out on top. I have always challenged anyone that asked to go to Amsoils website and look at their products and read the Typical Physical Properties, then go to a competitor such as Mobil 1, Castrol, Royal Purple, Red Line, Vavoline, etc and try and find the same exact information. You will find that it is nearly impossible and makes it very difficult to make an apples to apples comparison.
It is refreshing to see that they are and always have been that open about their test results. Ive been selling their products for over 12 years now and never have I been really disappointed in any of their products.
