[QUOTE="wildbillcody97, post: 672718, member: 10246"] Is there a big difference going to full synthetic on an engine this old? Is 5-40 OK to run it doesn't get real cold around here maybe 3 or 4 times a year under 10 degrees but from november to febuary has been in the mid 20s for the past couple years.I don't know that much about all the diesel oils.Just want something good since I have to have the truck to make money.
