Tundra Gas Mileage Video
 

Thought I would make a video driving from NOLA to Fourchon yesterday. I reset the gas Mileage and let it run. This included a stop at McDonald's drive thru...

You drove from New Orleans to Fourchon and never went over 70mph. Very impressed

I had a 2010 Tundra and never made over 15.

my tacoma gets about 17.... average.... thats impressive

I can confirm that with my 07

It's tough, but when I'm not in a hurry, it can be done.

I can't say for sure, but I think the supercharger helps.

It may. Is there any chance that the odometer and speedometer could be off due to your larger tires giving the computer a false reading? If not good for you. That's a strong mpg number.

Wow, that's very impressive for a Tundra, the mpg goes downhill quickly after 75mph but that's most any trucks.

Man how do you like that supercharger I bet that's a whole lot of fun? I can see the supercharger helping mpg when accelerating or passing.

Bigger tires and Speedos
 

Yes but lager tires will give you a false lower speedometer reading, based off past experience my guess would be about 5mph off.

Ex. Speedo shows 70 but really doing 75.

My old Isuzu Trooper with 31" Swampers (tires were actually 33")
was really going 78 when the speedo read 70. I confirmed those numbers with handled GPS and a speeding ticket going down 210 bridge.

Odometer matches the GPS pretty well. I should also add though, that because of the supercharger, I am required to run 93 Octane. I know that is helping out as well.

The Supercharger is amazing. I really love playing with cars and diesel trucks that think they're fast.

Im getting 20mpg in my 5.7 if i stay at 70mph and this is hand calculated. I had a 2013 but this 2015 is getting better mpg.

lets see pictures of your truck, 38" tires wowzer, i have a '13 4x4 5.7flex, i get 11-12 in town, and around 15-16.5 on highway with factory size 20s, that is me calculating, no fancy computer to tell me

Got 13mpg from Hammond to Grand Isle this weekend pulling my Tracker Grizzly 2072 MVX CC with 115 Merc.
