Highway trip to VT, 30 MPG no kidding did the math...

That's excellent considering the hills. Your average speed was 61. In the flat delta here in Tennessee, I get 32 to 34 mpg at 60 mph on good summer diesel. The EVIC tripmeter mpg, which uses a 300 mile rolling average, is fairly accurate to hand calculations if the driving style is the same for the entire tank (700 miles). It won't agree if half the tank was spent in the city before a trip.

I have seen 38.5 mpg on the EVIC at a very steady 55 mph for 300 miles nonstop when I was attempting to hyper-mile on extremely flat ground. Of course it is important to reset the tripmeter so the average starts over.

Thanks for the info. I have been resetting it but really didn't know why. My 61 mph average was with a bit of idling at a client site. This thing is literally a mobile office with the blue tooth and AC outlet in the back.

31's not bad but I've been cloer to Frank (34.2 was my tops) on a recent trip from Whidbey Island, WA to Bend, Oregon (beer festival!). I really love this engine and very happy with the jeep so far. As of this morning, I'm getting 24.0 mpg on my short 6 mile commute to base (city driving). At this rate, I'm filling up about once a month.

Pat,
34.2 with some mountain driving mixed in - very nice.

There are 3 Diesel Jeeps here on Oceana - we're about to overtake the oil burning BMWs

I've noticed that around 65-67mpg on the highway is the engine's sweet spot. Granted I'm not running AC and the Jeep wasn't loaded down to much either. But still...34.2 was damn good to see!

Hey guys picked up my Overland last week. Put little over 400 miles on it and I'm averaging 20 mpg. Does it take a couple thousand miles to break in to get better gas mileage? Thanks

Mine has never seen 20 mpg average. It got 29-30 on the trip home when I picked it up new. Reset one of your trip meters on a trip AFTER warmup while at speed. Drive 60-65 mph and you should see it average 30+. Make sure you are burning real diesel, not biodiesel. If you idle a lot or take short trips only, then you'll see lower mpg. If that is the reason for your mpg, you will be having other issues soon. Short trip driving and idling will cause you to fill up the DPF. Our vehicles require a 20 mile trip on the highway often so it can clean the DPF system....its call regeneration.

20 seems awfully low to me. Even with my short commute in city traffic each morning, I'm still getting well over 25 (26.2 is my avg so far and I filled up Thursday....90% city driving). I'm not a lead-foot either and don't run the A/C (it's the Pac NorthWest....who on earth needs it?!). I'd keep a close eye on that....just seems low to me.
