Nothing wrong with the Fram. I have used them for yrs. WIX are good also. I think I would Rotella T also but its not necessary. I think Id be temped to use just 30wt.You dont really know how much stuff (sludge) is in this engine. With the ROTELLA T which is a high detergent it may clean that engine and all that sludge will wind up in the pan and plug the oil pump screen. Trust me,been there done that.
GOOD LUCK
