Message: [QUOTE="Old OutLaw, post: 616957, member: 5413"] I don't like Delo....it runs ok, but is low detergent....I'm an old Cummins truck engine mechanic, (amoung other things), and every engine I tore down that had Delo in it for any length of time was scummy black inside.....we started using either Mibile Delvac, or Union Gauardol because of it, and the engines remained clean inside.... that being said, according to the Guy on The Diesel Register article I read here a while back, Valvoline Premium Blue is the best dino oil available....NAPA blue is the same and so is Cummins Blue...all same-same.... soooo...I changedd to it about a year ago, and it's much better...the viscosity seems to last longer and the engine just runs smoother, and after 50 years playing with all kinds of engines, and different oils, I would have never believed it unless I did it...
