What oil is everyone running? ive been using delo 15/40 since new. but thinking about going to amsoil. most syn are 5/40 tho. what do you guys think?
how hard do you drive your truck, towing and what not? i thought about ams oil but for the price and the fact that its not readily available is the reason its holding me back.
i run DELO 15/40 and used to run the ford stuff.
i dont run it that hard. but i do sit in traffic 90% of the time. i can get amsoil fairly easy so thats not a problem. just kinda wondering on the diff wt. going from 15/40 to a 5/40 syn guess i can try it and always go back to delo if it sucks or i think its a waist.
