I invite you all to go and do some research on your own.

I use the oil in all my vehicles and have experienced cooler running temps, better fuel mileage, and save money by having extended drain intervals. The vehicles I use it in our:
1987 Chevrolet Silverado V-8
1989 Chevrolet Camaro V-8
2006 Chevrolet Silverado V-8
2007 Saturn Aura V-6
2010 Chevrolet Camaro 2SS
Don't get me wrong RP and Mobil 1 are some of the better oils on the market but on the research and uses I have seen personally Amsoil is better. I work in the offshore industry and we have just recently switched to a RP hydraulic oil RP 22 from Shell Tellus 22 and have been experiencing all kinds of problems with our equipment. I know that is not related to the motor oil topic but just the most recent adding to the reasons I do not like/use RP.
No Amsoil does not come with soap, it is not Amway!
The Amsoil name comes from its developer AJ Amatuzio.
This is not a response to push the oil b/c I deal it. I could care less about that I am just trying to help fellow camaro enthusiasts with a good reliable oil that will benefit them and help protect their investment.
