Just wrapped up a 1800mile trip and it seemed to have poor fuel economy and consumed a lot of DEF for what we did. Averaged 22mpg which is terrible but I had 4 bikes on the back. Maybe they acted like a sail? I’ve averaged that towing 5-6k before. Also used just under half a tank of DEF. Today I noticed a lot of white residue/dust in the exhaust.
I believe I had a coolant issue before where it was disappearing but a few items were replaced after I hit a deer and so far it seems ok so I don’t think it’s from coolant but I also don’t know.
Anyone else deal with this? I run truck stop DEF, no additives and at 81k miles. Might clean the DEF injector this weekend.
