Thank you all, you guys are teaching me a lot. I am in Oregon, and the button on the pump said S15. Had never seen that before. I have a 2016 Duramax, so I better read the manual. My rig has only 3600 miles on it, and I have changed oil once, but not fuel filter. I better look into it. I need to find out how often the fuel filter needs changed. We got a foot of snow now. I can wait a bit. I don't drive it much right now.
S15 has NOTHING to do with biodiesel. it is the max sulfur content. And that is federally mandated and also mfg require diesels after about early 2000 to only use S15.
Oregon diesel will be 5% Biodiesel unless you fill at a pump that says otherwise, often "up to B20".
And the 2016 duramax manual says you can use B20.
Fuel filter life will show on the DIC. manual states a time duration or when it says 0% whichever is lower.
Thanks KT, I'm usually a fanatic about maintenance. I bought the Duramax thinking I would tow a fifth wheel. DW found out she has lesions on her spinal roots, and can't sit long, so went to a
motorhome. So the 2016 Duramax has been kind of a garage queen, but thanks for pointing out there is a time limit on the fuel filter. I'll be getting right on top of that.
