The Mobil that we are supposed to use is very close to the Amsoil. I always forget the auto parts store designation for it. It's the Mobil 4T racing oil from Triumph but at the parts store it's MX4T or M4XT or something like that. I think Bigbill knows the correct numbers and letters. I would agree 55 pounds or 100 dollars is more than any oil is worth. Thats just crazy!

I learned all I need to know about life by killing smart people and eating their brains.
