I have an F-350 diesel (7.3 power stroke) that I don’t use much since I retired. Probably put 1000 miles a year on it. Is it ok if the oil is a couple years old?

Depends where you live. If it’s hot and cold alot. I’d do yearly. If you don’t have that you could get away with more but I’d still try and get it done yearly.
