its never too late for synthetic fullthrottle. I became an amsoil dealer for the savings. I saved the money on the first case of oil. It costs me 22 canuck bucks a jug, ten bucks cheaper a jug than oem regular. I usually run 2 oil tanks of regular to seat the rings then run it down to less than a 1/4 tank of oil and then add the amsoil. I was also able to turn my oil injection down due to the better flow rate.
