Synthetic oils

Yep...heard the same thing from various people in the biz. Oil on the car isn't necessarily oil IN the car...LOL.

I stay with Amsoil because it has proven itself to me. I will concede the point that maybe my truck wills till be running at 120K with dino oil changed every 3K, but the point to me is that I can go 20K, use a fraction of the oil and filters and not spend the time under the truck every 5 weeks. If my buddy can go 230K, and only change his oil 9 times...they are doing SOMETHING right in the formula.

I will not say it is THE BEST because I have no empirical proof to make that claim. I also know there are other brands out there (like Schaeffers) that are also very high end, and I would be very comfortable using them, they are just not as easy for me to get (Amsoil regional warehouse is here in town).
