You can see from the data above that I am driving an average of 150 miles per day. This data is based on every fill up the truck has seen since the day it was born. This data is not based on the trucks computer.

I am in the plains, it is flat out here. Hills don't exist in my everyday driving.

I go about 3 mph over the speed limit, not the usual 5-7 mph I have been doing my entire life.

I am not pulling a trailer, and have my tonneau cover over the bed.

I run 91 or 92 octane gas.

I have no level or lift kit.

I have no lightbar or other wind blocking add-ons.

I am running stock wheels and tires.

I don't have trailering mirrors.

There is no reason to warm up the truck in the summer time.

My truck has averaged 14.689 mpg over its entire life of 5,246 miles. This is based on 18 fill ups over the course of one month and 4 days. I have never seen 18.0 mpg. I have seen as low as 11.298 mpg. These numbers are based on full tanks, not isolated snapshots in time.

I would expect to see fuel economy like this if I was pulling a trailer. I am afraid of what my actual mpg will look like when I do actually hook up a trailer.

Like I said, its flat, there's limited traffic, and I'm unloaded. Something isn't right here.

I got 17.0 mpg average @ around 1600 mileage and I believe your Platinum is much heavier than mine.

Can you post pictures for your wheel well liners?

hmmm, does sound weird, but let me try a few things:

- winds can be killer on the plains. Some of my worst mileage has been there.
- 3mph over 70mph(?) speed limit is 73mph. That'll kill your mileage. I know some areas where the speed limit is 75mph.
- could the gas have high ethanol content? That's not good for mileage, but sometimes the high octane gases don't use ethanol.
- 20" wheels and grabby All-terrain tries can cut into mileage even if they're stock

Geez, some of you guys drive like Grannies to get one more MPG. I don't quite understand that. I'd rather drive a weaker rig how I wanted to drive it and get good mileage than coast around in something with a beast of an engine to try and achieve mediocre mileage. No offense meant to anyone. I just don't understand the logic.

No offense taken. But a weaker rig won't get you up those hills when tow/hauling a load.

We use the power and fuel when needed, climbing hills, fighting head winds, but try to save fuel by going slower the rest of the time.

And, yes, some of us are grannies or grampas. We don't have the response times we used to have, and we drive accordingly. You should applaud us! Nothing scarier than seeing some senior citizen hauling down the interstate in a 15,000# combo at 75mph. Especially when his trailer tires are only rated for 65 mph.

I will applaud as I pass you in my current crappy daily driver car. I'll be driving with my knees as I applaud the fuel efficient driving style you exhibit.

I'm joking, of course. All in good fun.

2500 mi. now @ 14.2 mpg 80% city 20% hwy.

3.5 EB Platinum with 4x4 and 3.55

@ 2800 miles and avg. is 15.9 80% city 20% highway. I use the sport button everyday on the way home from work. I am addicted to the turbo whistle.

Maybe the answer is in your signature:

Platinum - is this a heavier vehicle than other trims?
3.55 elocker - this improves towing weight and hurts gas mileage due to increasing the vehicles rpms at a given speed.
Extended Range Tank - adds sprung weight which hurts gas mileage.
20" PVD Wheels - adds unsprung weight which in turn makes you accelerate a little faster than you might with 18" wheels.


I'm just taking a shot in the dark, maybe something else is wrong.

I have the same setup as this and a few posts back Bretcoe was thinking my MPG is a fantasy in the 20 mpg range. I think it's either the wind or driving styles.
