Figured I'd revive this thread. Almost due for an oil change, so figured I would post my mileage since February here in Nova Scotia, Canada. I've probably been averaging somewhere around 18MPG since the weather warmed up, and ~19 since I put on some Michelin LTX M/S2 E-Rated tires on.







I never averaged this with my 2011 EB 3.31 rear and 17 inch P-Rated tires, although I feel like my 5.0L just keeps getting better and better with the more miles I put on.

Sorry no pics right now, this old compooter has problems in that dept. But, we are at approx. 2500 miles into our road trip from North Carolina. We pulled into Livingston, Montana today with a 20.6 mpg average. High was 22.6 when we got to Lexington, Kentucky. We've been in some fairly heavy head winds while traveling west on I-94 the last two days, and that along with a 75 mph speed limit it has been dropping. Very satisfied.

Lifetime avg 18.8 with 21000 miles on my '13 5.0 screw. I am up to 19.3 since I started using premium gas and an AEM dry flow filter (according to the computer). 50/50 mix of city and 75-80 mph highway driving in Colorado. I couldn't be happier!

My truck improved s fair amount after putting the procharger on it. Averages around 24 on highway but have seen almost 26. That's not instant mileage btw.... impressive for a truck making 520+rwhp

Since new(march 1st) I have a lifetime avg. of 14.4 MPGs. Yesterday, I took a short road trip(130 miles) and averaged 20.1 @ 60 mph using cruise control, 87 octane w/ 15% ethanol. This was on a flat level road with very few stop lights, 10 mph crosswind, and approximately 987 ft above sea level. I'ed say I was fairly close to where it should be- what do you guys think?

I'm on my second 5.0 so I can comment on 2 different setups:

Truck 1:
5.0
3.31
2wd
Scab basic XLT with 17's
Averaged 11.9 L/100km or 19.7ish mpg

Truck 2 (Info in sig)
Average 12.75 L/100km or 18.4ish mpg

These are both hand calculated lifetime averages. I've seen my current truck get as high as 10L/100km or 23ish mpg on long trips at 100km/h.
