MPG Improvements 2014 Toyota Tundra 5.7 V8 TRD Off-Road

Good morning all.

I’m new to the pick-up truck world.

I looking to see if there is anyway to get MPG improvements on a 2014 Toyota Tundra 5.7 V8 TRD Off-Road.

Any and all help is great appreciated.

 

Good morning and welcome to the forum.

In short, no there's nothing you can do to improve mileage other than all the old-man tricks...slow down, keep your tires properly inflated, etc. Otherwise, if there was, it would have happened at the factory.

It's a reliable rig that will go forever as long as you feed it.

 

Thanks!

 

Two things can help you not worry about it so much:

1. Realize that it is only about 3mpg off of an Ecoboost or 3rd gen Tundra. Seriously. Don't listen to the "I got 20+ mpg on a highway trip" stories. No one is getting that over a whole tank unless they're driving the baby Duramax. Look at Fuelly for real usage, real world numbers. People average 16.x (with some low 17s) with a twin turbo v6 full size truck, while 5.7 Tundras average 13.x (with some low 14s).

2. Treat the fuel expense of a 5.7 Toyota as dealer repellent. Just keep feeding it and performing basic maintenance, and you have the absolute best chance with this vehicle of never having to go to the dealer, sitting and waiting for them to say hours later "we couldn't recreate the problem", fight for warranty work, etc.

It's the "never let you down"-ness of the 5.7 Tundra that makes it so great. For me, it is WELL worth the few mpg less and the half ton payload constraints unless and until my needs significantly change.

 

Thank you.

 

Keep it 45-65 mph and drive it like you have a pint glass sitting on the dash. This is more important than anything else you'll do, aside from not putting >33" tires on it.

My commute is 35-55mph for 46 miles and two lights. If traffic volume is light, the truck regularly does 19-21 mpg. I find it only does better than 20 if traffic volume is heavy, but moving steadily. I think being behind another vehicle helps.

Stop and go in town, 12-14 is normal. Flat highway at 65mph, 17-18. Above 70 or grades- 16.

For what it is worth, I found that switching from 0w-20 to 5w-30 made no perceptible difference.

 

Super charge it LOL

 

Thank you all for your advice and help

 

Not that you'd know this being new, but this question has to be top 2 all time in the forum. Sticky was made as a result. See below.

First, what is your current mpg?

Drive slower and use factory size highway tires. Or drive your wife's car if you don't need the truck.

 

Drive steady, like 62/63 mph, don’t take off too fast, just chill. I am getting 18mph but I drive slow, really slow. No real mods either but I’m preparing for 8.00-10.00 a gallon gas in Ca later this year.
Seriously I think we buy these trucks for dependability, longevity and the reputation they have as steadfast beasts. They’ll tow, they’ll last and they’ll drink, always thirsty but that’s the trade off.

 

You just have to remember you are either making big car payments or bigger gas bills.
