    Yes, warm weather and regular gas is helping to restore reasonable FE. The overall average MPG is rising and around 22.5/22.6 and my recent commutes have been closer to 24 in/25 out. I've been using a different route into work which shaves about 11 miles a day off the commute, avoids highways, and allows me to reduce consumption. The tradeoff is about 20 minutes longer in the truck (10 in/10 out). But the ride is also more enjoyable - goes through a few nice affluent townships with joggers...pretty ones. :)

    I wonder what they have improved over the years, the highway mpg stays at 25 but the city is up from 18 on my 2005 to 21 on the 2013? In 2007 city went to 20, then 21 in 2011. A few years along the way the highway has gone to 26 and then back again?

    Lower fuel consumption at idle? Lower viscosity oil? Different low rpm tuning? EPA gamesmanship?

    A recent run from Seattle to Vancouver and back netted me 19.5 mpg - almost all highway (93% or so of the driving was highway). Stuck to the speed limits, though 70mph stretches do hurt things a bit...

    No A/C.

    ...and while I'd love to do better, I think that's pretty good given it's a 4wd with 265/75/16s on it.

    While I agree 100% with what you say, there were more practical reasons... ;)

    1 - torrential rainfall
    2 - cool temps

    Just no need for the AC on that drive. Give it another month, though, and I'll be tipping into the AC more for the summer... ;)

    That's why I didn't say "Windows up > down"

    They probably took notice of the numbers you were posting (along with others in this thread) and figured, "What the heck!!" :)

    I've noticed across all makers that run an engine configuration for extended periods (several years) that they generally can tweak it for better MPGs and often times an HP here or there. Definitely gamesmanship in play here as you can see by the rankings, most trucks are within a digit or two so to claim top spot, not much needs to be done. Subtle refinements in the truck to smooth the lines, oil, different software for the idle/transmission shift points. I suppose the game can be played a number of ways.

    I've got an 88 22re 5 lug auto that'll do about 260-265 per tank. But it only takes 11 gallons to fill it up. So aprox 24mpg. This is just back and forth to work and general driving. And I never hesitate to let that 22re spin up. I wish my 99 prerunner would do that.

    For a automatic with a moderate load, and lots of short trips, that is not too bad. The main things to remember, is speed kills MPG, hard acceleration kills MPG. Drive like you have a raw egg under the throttle pedal, and see if that helps.

    Welcome to the forum.

    Towing anything and getting ~19 on the freeway is decent in my book.

    I indulged on my last tank and used A/C in the heat wave which dropped that one to 25.2 mpg. I gotta say the 2TR is one sweet little mill.

    No one at work believes a 4x4 can get 20, let alone 25+. Then again they mostly drive domestics with rust-enhanced weight reduction.

    Because my base model 2012 standard cab 2.7 5 speed manual is used as a work truck, I'm totally into economy and have been setting up my truck to get good gas mileage.

    [​IMG]

    I removed the air conditioning and power steering systems. Removed of the parasitic drag of the extra pulleys and idlers. Installed a way shorter simpler running fan belt.

    [​IMG]


    Put on smooth quiet Yokohama 235/60/16 low rolling resistance eco friendly gas mileage passenger car tires. Installed a LC Engineering exhaust header while retaining the stock exhaust so as to enhance low end torque.

    The truck always gets a fillup at around a half tank with regular 87 octane gas. So far I'm getting an overall average of 24.3 mpg town/rural driving with no freeway driving. The truck is always fully loaded with about 800 pounds of materials and tools. Translating that overall average to theoretically running a 21 gallon tank dry would yield a little over 500 miles.

    I've read that you should never a fuel injected vehicle run dry as the fuel pump can get damaged.

    I think this might be a little extreme. A/C doesn't really affect mileage unless it's being used. And your steering rack is not designed for long term useage with no hydraulic assist. I think not running p/s will end up costing more money in the long run than your saving in fuel. The best up grade for fuel savings under the hood is probably electric fans.
    But I digress. It's your truck.

    Yes it is. :)
    I enjoy driving a simple basic no-frills vehicle, and since these days it's all but impossible to buy one that comes that way, I make it the way I like it.

    Even with the hydraulic assist, exactly the same forces are acting on the steering rack. You just don't feel it because the hydraulics prevent any road feedback from returning to the steering wheel. I like to feel the road I'm driving on because it makes me a better driver.

    I removed the power steering on my gen 1 Tacoma the day I bought it, and drove it for 17 years with absolutely no front end issues, uneven tire wear, or steering component failure.

    !'ll continue to use the many years of my own personal experience as guidance. :)

    Another gas mileage consideration is wheel weight:

    1lb. rotating weight = 10lbs. static weight.

    When I was running big heavy clunky 245/75/16 truck tires, I could barely break 20 mpg even with odometer correcting for the 13% larger wheel diameter than stock. With relatively light low rolling resistance 235/60/16 stock diameter passenger car tires, my truck consistently tops 24mpg even with no freeway driving.
