I have 05 dmax with 147000 miles what oil is best also what fuel filter, i used lucas in every oil change on my vortecs do they make somethin similar
I havnt blocked the egr yet on my truck. I'm not sure what kindof difference to expect when I block the egr on my LB7 duramax(2003-20041/2) year model.Ok i c, yea ive used lucas in all my high mileage vortecs, just curiouse does ur truck have the egr block plate, if so when did u put it on and did it make a diff thanks
It would probably make it go lower with synthetic, hence 5w-40, instead of 15w-40. But I'm just being speculative.Not tryin to jack the thread, but is it ok to start using synthetic oil at 200,000. I have a pet peave about oil pressure and I want mine to be higher. I have always used Synthetic in my gas burners, but I'm new to diesel. The OP always picked up when I went from dino to syn.
They make synthetic lucas, black label.Im a lucus fan and I think thick oil is good. I use any 15-40 oil. I use Rotella in my tow trucks and Valvoline in my dmax. As long as you dont use synthetic Lucas is fine to use
