clyde fernortner garbage7@wavecable.co oil news again…delo has come out with a '10/30'…i like ‘valvoline all fleet’ they have excellent diesel oil, and mobil/eexon, texaco ursa is another excellent brand…i always tell people to read the “bob is the oil guy” website…check his “oil university” study…10/30 is the best multigrade! at our local ‘mobil/eexon dealer, they always ask what engine you have, and how old it is, then give you the proper oil for your engine!…clyde
