HOT150

Checked mine again. Got right at 12 mpg today. Lifetime average, last 22 months, is 11.6 mpg. Mostly city driving, short runs.

Just clicked 20,000 with a lifetime average of 17.1 mog. That includes the random tank of E85 to clean up the engine and for a little fun. Truck driven fairly hard.

Anyone got longtube headers on yet? I don't think just a muffler change is the ticket.

Trip I took last July from Louisiana to Delaware and New Jersey and back...18.1 avg with a loaded truck and running the posted speed limit's.

I make frequent trips from Oklahoma to Houston and run 70-75 and get high 17mpg. Only time I got into the 20mpg range was going 55ish thru construction. I have been running 93 octane in my truck and haven't really seen any improvement. I drove my truck off the lot with 200 miles on it and now it has 7000 miles on it. The mileage has stayed the same.

'13 XL Regular cab 5.0 6.5' bed with 3.31 e-lock. Was averaging about 17.5 overall, and usually got around 19 hwy but that's doing 75-80 staying with the idiots. Towing 5,000-6,000lb loads it gets 12-17, depending on terrain, speed and other variables. I won't complain.

I installed a soft roll-up Truxedo cover last week and my readout is now 19.3 average. I kept it over 21.8 (even hit 22.5 for a little while) hwy running 75-80 for a couple hundred miles yesterday. This truck's sweet spot is 50-55 though. If I can keep it there and play with the go pedal right, it gets stupid good mileage, but good luck staying 55mph very long in GA with some of the clowns we have on the roads here.

A 5.0 in a regular cab short bed is very fun though, and can get very poor mileage if you keep your foot down.

I'm still amazed that this 5.0L is getting as good or better mpg's in some instances than my previous 3.7L.

The trucks and SUVs I compared mpg:

2000 Nissan Xterra SE 4WD SUV with 3.3L SOHC V6 with 4 speed auto (170 Hp @4800 rpms, 200#s Torque @ 2800 rpms)

2004 Nissan Titan XE Crew Cab 4WD Off Road with 5.6L DOHC V8 with 5 speed auto (305 Hp @ 4900 rpms/379#s Torque @ 3600 rpms)

2005 Nissan Pathfinder SE 4WD with 4.0L DOHC with 5 speed auto (270 Hp @ 5600 rpms/ 291#s Torque @ 4000 rpms)

2008 Ford Explorer Sport Trac XLT 4WD Pickup with 4.6L 3V SOHC V8 with 6 speed auto (292 Hp @ 5750 rpms/300#s Torque @ 3950 rpms)

2010 F150 XLT Crew Cab 4WD with 5.4L 3V SOHC V8 with 6 speed auto (310 Hp @ 5000 rpms/365#s Torque @ 3500 rpms)

Current 2012 F150 XLT Crew Cab 4WD with 5.0L DOHC V8 with 6 speed auto (360 Hp @ 5600 rpms/380#s Torque @ 4250 rpms).

I'm getting the best mileage out of all of the them with my 2012 F150 5.0L truck. This truck is great with great mileage, just below par reliability.

I did a little towing thru the mountains with my truck. My trailer is about 4k. The way to my destination, I was driving uphill at 50-60 mph. On the rolling roads, 70-80 mph. There was some around town driving too and up more mountains in the snow. The way back was snowy and used 4wd for a hundred miles or so. Once the roads dried, I was back up to 65-80. My average mpg was 11.1. I'll accept that given the conditions and that I went over about ten mountain passes ranging from 10,000 to 12,000 feet high.
