Fuel economy

I'm looking for ways to increase my fuel mileage. I have seen a cheap chip online by GForce garaunteeing increased fuel economy. Not sure if its legit but would appreciate any input on ways of increasing it. Only had my 2012 Crew Max for about 3 months so Im new to this. Any comments are appreciated.

Brother, you bought a truck that weighs three tons and has 400 hp. Don't worry about fuel economy and instead concentrate on improving your quarter mile time. Did you know the TRD supercharger can actually improve fuel economy under light loads according to TRD.

Thank you for your reply. Not really looking for quick 1/4 mile times though, more interested in street/off road performance and look of the truck. Plus I am really interested in anything that will pick up the fuel mileage of this 3 1/2 ton beast! LOL I dont mind filling it up at $80 a tank and 10 minutes of my time cause it rides like a dream but if I could get 17-19 mpg like some competitor owners are telling me they are getting that would be awesome! Again, thank you for your reply

Buy real gas, none of the crap that has ethical in it.

Other than the super charger, nothing yet other than a light foot will help increase your fuel economy. Computer learns the way you drive and adjusts to it. Keep a light foot, but once every few weeks stand on it to blow out the junk.

BTW, does the supercharger "actually" increase fuel mileage?!? If that is accurate the cost of it would be worth the fuel mileage/embarassing other truck owners on the highway! Please explain!

Yes it does, according to a statement on the TRD website. At light loads it actually increases the volumetric efficiency of the engine. The trouble is, most people cannot maintain a light load with 500 hp on tap.

The only way to improve your fuel economy on the Tundra is to sell it. You don't buy one of these trucks and expect it to be fuel efficient.

My YTD averaging mine is 17.4 according to fuelly.

I run 70 when on the highway, have my ac on, heavy e rated tires that are fat and beefy. I also have a tonneau cover, a drop in serviceable air filter and an aftermarket muffler (strictly for sound). My mpg goes way down when I'm in town or put a load on it. Just keep a light stardy foot and it will get decent once it gets broke in.

As fir competitors getting 17-19, I call bs. Unless they have the v6 version, I think we have seen where the egoboost can't even maintain its mpg when driven in the real world.

Thank you! I appreciate the input! My truck is new and I hope once it's broken in it will get better. I dont run it hard and only have the TRD exhaust as extras so maybe it will improve. I'd love better gas mileage but I'm also not willing to give up my "horse" for a corolla, (which I have one of those too! LOL)for fuel economy. Just wanted to see if anyone had some insight or knowledge of creating better fuel economy in a tank of a truck!

Fuel economy is predicated to the laws of physics with a vehicle of that size, but you can approach the problem from other angles. Plan your trips so you take care of many errands in one trip instead of several. Don't warm it up too long in the mornings, just a minute or so, then easy on the throttle while driving until it fully warms up. Don't idle while waiting for trains or drive thru coffee....shut it off. Tires inflated to just under max sidewall rating, etc.

When one buys a truck this massive, one should know that a gas guzzler is part of the deal. Eitherway I wouldn't trade it for anything!

Yeep, you don't always gain by trading either. There is the matter of depreciation.

I get 18.1 in my dc. 95% of my driving in on highway to work and if i need to drive around town i take the wifes hyundia. When i go to work at 530 i put it on cruise between 68-70, no traffic that early in the morning so i can drive slow. I have a K&N and a throttle bodyspacer. I bought one of those so called gain hp tq and milage....It was a crock!!! A light foot will def help you out but thats hard when you have 400hp right at your feet. I also have a armor lid cover, get a cover and that will help out a bit, not huge gains but when i put mine on i saw a small difference.

Your truck is 2wd yes? Mine is the RW package including tow.


Light foot, good gas, proper maintenance and a light foot.

I have no mileage complaints at all. My '08 DC 4x4 5.7L is getting between 16.4 and 18.1 MPG depending on the type of driving I do. For a 5800lb, 400HP truck, that is amazing stuff!

It is even managing 14.8 MPG while towing my 3000lb boat and trailer! I maually calculate my mileage at every fill-up and have been nothing but pleased.

Compare this to my buddy who owns a '12 F-150 Ecoboost that is averaging 15 MPG and, frankly, there is no comparison.
