I started using AMSOIL products several weeks ago. I have AMSOIL 5W-30 and an SDF oil filter in my 2002 Chevy Avalanche. I have about 1000 miles on the new oil. Has it made any difference? I don't know, however, I do know this:

I use AMSOIL Series 2000 20w50 Racing Oil in a 1979 Ford Mustang that I drag race. Last Saturday, April 10, 2004, I took the car to the New England Dragway in Epping, NH for a "test and tune" day.

As usual, I did my burnout and started to stage the car looking at the oil pressure gauge for the last time before the run was finished. The gauge reported the pressure was normal. I made the run, shifting at 6500 rpms. When I crossed the 1/4 mile I looked down. I had no oil pressure! I turned the car off and rolled as far as I could before starting the car and bumping myself ahead to get back to my pit stall. Earlier in the day, we had a problem with the tubing going to the gauge, so I didn't believe the gauge completely. To make a long story short, I should have. Sometime over the 11 1/2 second run, the oil pump seized up and broke the oil pump shaft in two.

On March 13, 2004, we completed putting the motor back together, and I just want you to know I had zero damage! I can tell you this motor went a very long time without any oil pressure and had no damage! I can see just from this "little problem" that I will be using AMSOIL for a very long time to come!
