i get anywhere from 13 around town pulling stuff, to 18 on the highway. i noticed a 1 mpg loss when i went to 265, fairly aggressive tires.
not to hijack the thread or anything, but does anybody else see a drop in mileage once the winter fuel blends start??
that twenty minute warm up kills your mileage even if diesels dont burn much at idle. Why dont you plug it in, or just wait till the alt guage goes up to normal and then start driving?Not as good as I was hoping for.
I get 12-13 in the city with or without winter warm up. I drive 20 miles daily total and +/- 20 minutes of warmup at cold temps. I get 13 hauling a camper and towing a boat or an ATV trailer. I don't do much empty highway driving so I don't know truly what I get on the highway. I got 17 mpg driving 100 miles start/stop & then 100 mile round trip on the highway.
