I'm thinking I'm opening a can of worms here, but I've been waffelling about using synthetic oil in my Cummins. I'm due for an oil change and am wondering if I can get double the miles from synthetic as I get from Dino. Syn is running about double the price of Dino for a gallon at Wally. If nothing else I'd rather go 10k instead of the 5k schedule I'm on now. Have Syn in all the family gas engines and have had good experience with it. Use Mobil 1 in all of them. What do you guys think?
Thanks, Mike
