24 mpg @ 60 mph for 185 miles

 

Just got back yesterday from a weeks trip to Greer, pulled my toyhauler which is about 8k lbs from Phoenix to Greer going from about 1000 ft to 9100 elevation and got 11.3 mpg hand calculated for the 630 mile round trip. Oh and I averaged around 65 mph.

 

15 MPG while pulling a small trailer about 5k LBS on the highway. I was quite impressed with that so i had to calculate it twice. Thats using the Edge Evo HT on the economy setting. Straight pipe and more air helped too

I generally get around 16 mpg doing my general everyday mixed driving. I've gotten just under 18 mpg on a road trip. I think this is not bad but also not great. Everybody always wants the 20+ numbers. My Lie Meter always says I'm getting around 20-22. Wish they made that a little more accurate.

 

Just under 18 mpg on everyday driving.

 

Before i lifted mine a got 22 highway/ or around town, but cruisin at around 50 for a few days i had it up to 25-26 witht the adrenaline on eco, now with the 37's i can only get 17 out of it

 

We just got back from a 4,000 mile trip to Idaho, Montana and Utah pulling a 8k bumper pull toy hauler mostly @ 65mph and averaged 9.85 for the whole trip. I have no idea how so many are pulling 12-15k 5ers 65-70 and getting 12-15 mpg and empty 18-25+ at 70+ but in my real world that's what I got all hand calculated.

 

I'm with you Gerry, I wish I could get those numbers too. I pull 10-12k often and get about 12mpg, depending on the route and wind. when I pull really heavy, 18-23k, I get 8-9mpg. My best highway cruise has been 19 mpg, no load, on 10 in southern LA. I think I would do better with a manual. Had one in an old 2002 and it routinely got about 20 mpg.

24-26 mpg, Magnaflow pipe, Bullydog PMT module in tow mode, Volant air box. pretty much doing 60 -70 mph on highway and speed limit in town. But then put on 185-17-70 tires and lost 2 mpg, thought it would improve mpg, not decrease it. 3 speed auto 3500 heavy duty 2005 model.
