I'm unsure of the whole weight of oil situation. Zinc additives are what I heard are good and ive put a zinc additive in the oil as a part of the oil change routine. I've mainly used 5w30. what oil weight should I use it I had for the rotella? I live in md it's a range on cold winters being sometimes 20's-50's ferinheight and 80-100F in summer.
