This one's a keeper.
Boy, I sure get a warm fuzzy feeling about using Amsoil when I know it's not tested. Yep, a cult zombie message board spammer telling me it surpasses all the tests is good enough for me.
Screw the testing, it only costs money that could be going into the pockets of the MLM pyramid dwellers. I prefer my oil completely untested and completely unsullied by any certifications (which, we all know, place an absolute upper limit on the performance).
