    i just bought a 2006 w3500 cabover and i was wondering what brand and weight oil to use. i cant find any oil that has the api rating in the manuel. i am leaning towards a 10w-30 in the winter and maybe a 15w-40 in the summer. what do you think?. also should i use oem filters.......clay

    I use rotella 15w40 as well and buy isuzu filters. For some reason filters for my npr are $25-30 and filters for my frr are $8.
