Wow, I just learned alot! I go to the jiffy lube. I finagle with them on their price.(A girl can always get a discount) I like to use (for no reason) Valvoline High Milage 10w30. But, the place I used to go to(Superlube) cost too much. $30, I' do it my damn self. So I go to the new place. They don't carry High Milage. I think they used just 10w30 cant remember now. My question is: Is there a difference in the high milage? Am I just a sucker?
