In a 70/30 Highway to Street with my 2013 SCAB 5.0 4X4 W/ 3.55 gears I am getting mid 19's from tank to tank with the highest at 20.3. I currently have 7800+ miles on the truck. I am easy on the MPH and keep my revs to just under 2000 rpm. Never used any E85 fuel, not available in my area.

2000 F150 5.4L 4x4 Reg. Cab 3.55 with 305/70r16 mts. Finally got a 250 mile trip in after I installed my efans and managed a 18.8 mpg. Not too shabby for 200k miles.

How many people do the mileage calculation themselves VS using the Computer ?
Wife's Murano I found the computer was way off, skewed to give better results
By the MFg perhaps ?

Just did mine. It's really close. In some cases calculated is higher.

I have not logged readouts, just going from memory.

Dang, now I have to add columns to my log.

Started out bad, improved and then leveled. What do you attribute that to?

I am just breaking her in, but I did my very first fill up yesterday... Yep it's that new I only have 411 miles on it! But I GO VERY SLOOOOOW and excellerate SLOOOW on purpose. I want fair mileage and have the 3.7L V6 I got 21.76 overall out of it and bested 25.2 MPG's! I do 90% Highway though. After 1st oil change with FULL SYTH... which I already purchased (I'm going to post why on another thread) It will average 22.5+ every fill... Take care guys!

I use Fuelly. My current lifetime average is 15.8. It only matches what the truck says when I don't have a lot of idling. My in town norm is somewhere b/t 14-16. Depends on how many trips I make on the highway. I usually run mid-grade (88.5). Best observed is 22.6. Worst is somewhere around 10 (it was -50*! ).

This is after 1000 mile road trip - Anchorage, Fairbanks, Delta Junction, Fairbanks, Anchorage. Some city stuff thrown in. Summertime weather - temperatures from 50-88*.


40 mile stretch of highway b/t Girdwood and Anchorage. Reset when we left Girdwood. Not a flat stretch of ground. Fall weather - temperatures 40-55*.


I use the same username on Fuelly for those that want to check it out.

FWIW, they also have a compatible app available in iOS - called GasTracker. Haven't checked to see if it's available for Android. I use to use Road Trip, but have found Fuelly to be better b/c I can look online as well.
