Engine Oil

Amsoil is the way to go. I was using competitors oil and temp. was not good. Used Amsoil synthetic and brought temp down 5-7 degrees. Been using Amsoil synthetic after 700 miles on new engine and never changed. I would not move to synthetic if allot of miles on your engine. Also synthetic is thinner, so can get to other regions of engine that normal oil cannot. Net effect is longer lasting engine. Then I got aftermarket radiator and oil cooler and brought down temps significantly more.
