    So after doing all of my experiments during my trip from Georgia to North Carolina I've achieved a new fuel ecnomy record.

    (Updated, I mis-typed the calculation)

    28.07 mpg over a drive of 139.4 miles.

    I did several tests and this was the best one. There were a few times that situations interfered with my driving, so I'll estimate the max I could have gotten would have been 28.5-29 mpg.

    Alright, time for someone to one up me. Let's go!

    Specs for those who want to know:
    • 2011 Prerunner v6 4.0
    • 207,000 miles
    • 3"+ lift all the way around
    • 100+ lbs steel plate rear bumper
    • Michelin Defender Tires
    • Running boards (presume they are not aerodynamic)

    Mostly stock with a few minor mods.
    Check your calculations again. The pump says 4.966 not 4.996. You did better than you think.

    Pretty much 17 to 18 mpg average no matter what for me, only way for me to get 27 mpg is with a tailwind and downhill, never getting that mpg normally.

    Next long distance trip, put another 2 lbs. of air in the tires and go for 30. Pick a day when the wind is blowing the same direction.

    My average over the last 6 tanks is 27.7 mpg, worst 26.8, best 29.2. I4 manual prerunner, stock tires at 40psi. Best single trip per scangauge was 31.5 mpg over 32.1 miles( return trip from work). Worst trip 160 mile highway trip into a 25 mph headwind nearly the entire way for 24.3 mpg.

    I recently got this truck a few months ago, look up silvertaco on fuelly.com for each tank if anyone wishes.

    Speeds to/from work 45 to 60 depending on traffic. Highway speeds 62 to 70.

    What speeds were you driving?
    Best I've ever worked out was just under 24mpg which was all highway. Usually around 17 or so from city/highway mixed driving.

    Dang instead of buying that brand new Corolla for my wife I should have just bought a 10 yr old Tacoma. There's only a 3 to 4 mpg difference apparently.

    I got my best mileage at 25.7 with cruise control set at 70 for a whole tank. Stock truck with Michelin defenders. Yea to the OP, the defenders rule!

    That fill up would have cost me $17 where I live.
    That’s incredible MPG that you got. How fast were you going?
    I average 18 +/- 0.5 mpg on my 85% highway / 15% city 45 mile round trip commute to work. Highway speed varies from 65-75 mph.

    Just got home.
    So I was actually thinking that we should come up with some kind of official challenge to achieve 30. Haha

    I think you have already clenched that title. When I got my best mileage, I was trying to achieve the same. Granted I had 300lbs. In the back +/- but I ran over 300 miles on cruise control@70, I was very patient. You will go down as the king.

    55 mph 95% of the drive. trust me it was a bit difficult because some of the roads only had two lanes per side... There was a lot of quick maneuvering to allow big trucks to get around

    you know me and my girlfriend were talking about that, what would a Corolla be like with the Tacoma's v6? Haha

    55 mph 95% of the time. It was difficult but it's definitely doable. It would be even easier driving on interstates that have more than two lines per side.

    As far as speed and mileage goes. I found out as long as you stay around 70 with no pedal to the metal passing you should be fine.

    I’ve averaged 28 on a whole tank, but no cool pics to show it.


    2.75” lift, shell, 265s. Nothing too spicy.

    Well I always average 21-22 mpg for my daily driving. The highest I had achieved before was 24 mpg, but that trip had a lot of extra nonsense which is why it wasn't as high haha.

    It would be cool to try two different runs to compare.
