I use their products and have been for years but not exclusively as I use and try other vendors products as well. I see many people in different forums saying the claims Amosil makes about their products are not true. They say many of their products have not been though industry standards qualification processes and the test results they post are not accurate as they paid for the testing. It could be me but it seems I am seeing a rise of people with this opinion. On the other hand I see oil Analysis on the forum for Amsoil that look pretty good as well as the analysis I have had done are not to bad. My question is Is Amsoil a superior product that can take the abuse for extended intervals, provide superior protection and not sheer out of grade or is it like the doubters say just hype. And are the test results they post bias or bought? I am trying to figure out if I should continue to use their products or switch to something more affordable like Rotella. If the quality and added protection is truly there I do not mind paying a bit more but if it is not why waste my hard earned dollars.
