Diesel MPG and DEF

[Vegas_Blue]

So, I’ve clocked 6k miles since purchasing the JTRD in July. Mostly highway miles in the last two weeks: Nevada>Tennessee>Oklahoma >Kansas and about to arrive in Colorado for the Overland Expo. Averaging about 80mph and 22mpg (by my calculator). My calculator numbers are about one or two mpg less generous than the JT’s computer calculations. Stock 33s and few hundred lbs in gear. Had to fill up DEF AT 2,500 miles which was surprisingly early. The first leg was Vegas to Flagstaff so a lot of climbing. Maybe that’s why it ran out so quickly, or maybe it was low already from the dealer (I didn’t really pay attention to the DEF gauge when I left the lot). But good news is I still have 40% left after the last 3,500 miles. I can live with that. Passing on the freeway does not disappoint. The photo is about 1k miles ago. I know it’s the honeymoon phase, but I’m still in love.

Most people claim an efficiency in DEF usage after 5-10k. I have seen this with mine.

So far I have averaged better 26mpg over 1600miles mostly highway with a fair bit of FSR.

I started using hot shot 6 tanks ago i’am using 1/3 less def than before more than enough to pay for the additive. Mpg seems the same turbo lag seems a lot less

my diesel is a wrangler so it's a bit different, but I'm averaging 24MPG over 31,657 miles, with an average of 39/mi/day.
Max MPG was 32.812, minimum was 15.691.
I had TWO times where I failed to record a fill up, and I'm pretty sure one of those times was when I filled DEF so I don't have accurate numbers on DEF consumption.
First DEF fill was 4,438 miles. Next record was 27,734 and its currently sitting over 50%
