I used Amsoil for a long time with excellent results. One day I found out that they changed the way they make their oil, they started making it like everybody else.
I read some comparisons and there was no difference between the new Amsoil and Mobil 1. That's when I switched to Mobil 1 and saved money buying it at WalMart.
On the last oil change I tried Castrol Edge because they made some claims that they were so much better than Mobil1 and Mobil never contested them.
