[QUOTE="lincolnlocker, post: 528119, member: 944"] with it being amsoil you might not notice much... when i first got my truck i tried a couple different synthetics and the 15/40 amsoil started better then the other brands of 5/40... it will only help but i dont know if its worth switching unless they are the same price, why not. ive never had a problem with my truck starting with delo or premium blue 15-40 even in the -20s in minnesota winter while working out there. live life full throttle [/QUOTE]
