That's the kind of mileage I can get on our highways If I want to. I do quite a bit of in-town driving so my RAFE is 14.9L/100km, and I drive like an idiot alot of the time. Ever since I tuned my truck with an SCT it's just gotten better and better.

 

My computer says 11.1 MPG right now at about 1/3 of a tank in. That's what happens when you idle around for work and never get above 25 MPH most of the day. And if I do go on the road, it's usually hauling something. I think my last tank was about 12.5 MPG. 09 5.4

 

Here, you can see my speedo and tach. Its only been in the last 1000kms that it started to get good.

 

This is what everyone else is getting towing 8000 lb!!

 

Nothing BS about my numbers, they are exactly as they were the entire trip. The picture was the only clear frame from 1 minute of video (too much vibration and sound cutting out). Video was taken 100 km into the trip, my buddy behind me in my old Pathfinder kept telling me to speed up because people were passing me - haha.

No reason to lie & mislead people. I keep my truck under 1500 rpms and use the engine torque to move the truck, not the revs.

I had a run a few days ago driving 89 km/h (yes I was THAT guy on the highway) and truck computer was consistently reading 7.6L/100 km - 8.2L/100 km. Slow - yes, but the engine was sitting about 1000 rpm in 6th gear. Had it sit there for about 10 minutes on absolutely flat ground (Calgary to Airdrie in the ditch/slow lane).

The truck WILL do it. When I get my Scan gauge setup (mounted where I want it) I will mess around and get some video. Doubters gonna doubt - but driving habits are most of it.

 

I'm not doubting the mileage, you will get that, I am questioning it at such a low break in point with only 1170kms. It took me 8000.

 

Fwiw, I posted this about a year ago, but it quickly got buried:

I got some good results from our ~2400 mile road-trip.

2011 EB, Supercrew 2WD XLT, 3.15 gear, 14-16000 miles, conventional oil, Injen intake, bak-flip bed cover, and [gasp] 87 octane fuel.

We had 6 passengers and a bed packed full of luggage. Interstate speeds were 70-75 mph.

Results were, by tank:

miles truck-meter pump-meter notes

569 23.4 24.0 only tank on pure gas
448 22.0 22.2 more hills, e10
601 23.7 24.5 some stop-and-go but a lot of 55 mph limits, e10
552 22.7 24.1 rain storm, e10
201 22.5 22.8 continuation of storm, e10

Total was 2376 miles and 23.0 (according to gas station, hand calculated)-23.7 (according to truck meter) mpg, which I thought was great, especially considering the load.

With 25000 miles on my truck, my lifetime average is 20.2 mpg.

 

And my mileage vs speed data, which matches the cleanmpg curve well:

Mph - mpg (pure gas 87)
50 - 34.2
55 - 30.1
65 - 26.8
70 - 24.5
75 - 20.9
80 - 19.5

 

Those are GREAT numbers guys ! Looks like I'll have to go run a few more differing speed tests on my truck, thanks & I'll share the results when I get em !

Have I mentioned how much I love this engine yet ? haha.
