It was many years ago but none the less we had a problem with the Amsoil products and they would NOT stand behind their claims. We sent the oil to three independant labs for testing (at our expense) and all three sent reports that the oil was bad and had done significant damage to the engine. The oil had been in the vehicle for 20,000 miles (their claim was it was 25,000 mi. oil). The filter was changed at 10,000 mi. and a Quart of oil added. The engine lost oil pressure and was leaking at every seal. When I drained the oil out with a warm engine it came out very thick. I called them several times demanding a new engine and they would just hang up on me. So I hope all who are using their product have good luck with it but I will never use their product again. Sorry for the lengthy post but I had to add my .02. The engine was a Cast iron 4 cyl. (GM) with about 50,000 mi. on it and ran pefect before Amsoil.
