I know everyone has an opinion on this, but I have a 1995 5.8 Eddie Bauer with 140k miles on it I got from AZ. The previous owner used 20/30 or 20/40 oil due to it not getting very cold there and I live in Arkansas where we have hot, humid summers and we're heading out of winter. I'm getting close to needing an oil change so I am looking for what oil is best to use in it (oil type, weight, etc.) It is not my daily driver, just used as a weekend ride. Any help or suggestions are appreciated. Thanks!
