I have typically been averaging 17mpg on longer trips with one trip averaging just under 19mpg on a trip from LA to Santa Barbara and back.

You must drive like a rally racer. Why so low?

My last tank I calculated 14.9 miles but had a lot of idling.

No clue. Windy and rainy on this last tank.
I'm not hyper-mileing it, but not lead-footing either. I set the cruise at 8mph over the speed limit when on the highway, which is actually 5mph over; according to GPS...
So, 75 on the interstate today for the final 250 miles of tank 5.

Based on a handful of people who aren't on the forum, those are pretty accurate numbers; especially if your highway speed is >75-80

Are NAS owners using 91 octane? My intention is Sunoco 93.

I have to reevaluate my local stations. I’ve only been buying regular and diesel

16.1mpg 75% hwy driving.

The 3.0 petroleum doesn’t require Premium (US) grade fuel.

with a compression ratio of 11:1 and a turbo? Sure it does.

 

[pmatusov]

Gas mileage over a 2600-mile highway trip in the U.S.: 14.4 average (total miles driven divided by the number of gallons paid for at pumps). Variations:

Some discussion of that can be found here.

2) 14.1/ 16.1
3) 13.4/ 15.7
4) 14.3/ 16.7

This matches very well with my observations of real vs. ECU-computed gas mileage.

 

[Mountain4x4]

Things like elevation play a big roll as well. I doubt I will ever see anything over 14 MPG as I never really drop below 5,000'.

After 3 fill ups, about 600 miles on the truck now.
1st tank netted 15.9 combination city/hiway (Per the computer
3rd tank, all hiway, 20.7 per computer but hand calculated at 17.9.
I'll be hand calculating several tanks to see if the computer starts registering more accurate MPG.
I thought days of computer inaccuracy reporting was over. Most of my newer vehicles the computer estimate was very close to what pen to paper numbers were.

That‘s pretty good. Plus you’re at what 5000-6000ft above sea level?

Fuel mileage should improve as altitude increases.
