    If you have done the math correctly, ethanol free gas is the key. I could have pushed 21+ in my 4wd with ethanol free a few times. Unfortunately it is $.50 more per gallon, and not worth it imo.

    Yeah, math is correct. I get significantly lower mpg when I don't run it, however it is cheaper according to this: http://www.roadtripamerica.com/fuel-cost-calculator.php not even considering the damage that ethanol does to your engine over time.

    Topic was discussed here in a older thread http://www.tacomaworld.com/forum/2nd-gen-tacomas/217978-ethanol-free-gas-2-weeks.html

    Luckily the price difference here isn't as drastic, last fill up I believe it was only a twenty nine cent difference

    Running regular gas I was getting closer to 17mpg around town and 20mpg was the best highway pull I was able to manage usually right around 19

    I can't justify the price. Ours is 91 octane too, so they get you on that also. I have faithfully started running it in all my tools and toys though.

    19.1 MPG in summer. :woot:
    16.2 MPG in winter. :censored:

    Combined, roughly 60% highway and 40% city.

    I've read the last couple pages of this thread and haven't noticed anyone mention speedometer correction when calculating fuel mileage. If someone already did I'm going to reiterate.

    For anyone running over or undersized wheels/tires, remember unless you've had your speedos corrected either by calibration or with a module it is wrong, and that affects your odometer, and your odometer affects your fuel mileage calculations.

    Under sized tires or wheels have to turn more rotations to get you the same distance and will give you an overly rosey reading on mpg. Oversized tires travel farther with each rotation and will give you an incorrectly low reading. There are correction multipliers you can use if you know your original tire size and new size.

    My mostly stock Prerunner Tacoma with stock tire outside diameter and mostly highway driving 65-75 mph with a little bit of city driving gets 18.5-19.2 mpg reliably. If I idle a lot or push it it drops to no less than 17. I currently have 180,000k miles on her.

    Pulling trailers it drops like a stone. 400 miles pulling a 6x12 enclosed uhaul trailer netted 11.2 mpg, and I average about the same pulling a pontoon boat or my company's Bobcat on a tandem axle trailer.

    To add to what Pete said - it even happens with oem tires. As they wear, they become undersized, and give less accurate mpg. My dunlops were a full inch less in diameter when replaced at 37,000. If you don't use GPS, check your odometer against 50 miles by mile marker at least every 10k miles to determine odometer error.

    Most of Florida has high humidity which, like high altitude, reduces the amount of available oxygen per cubic foot of air. The humid air is denser than high altitude air so there would be some extra aerodynamic drag. The barometric pressure sensor knows there's less air pressure at high altitude, there's no humidity sensor so adjustments rely on the O2 sampling. In the warm humid climate most people will run their A/C all the time, not so much in the mountains. When my Taco was in Miami it averaged 18MPG, in L.A. I'm getting 20+. If I didn't drive 80+MPH every time I get on the highway I'm sure it'd do better. In Miami it was my dad's truck so different driver, but he didn't hot-rod it or haul cargo. The only things he did that would negatively impact the mileage is running the A/C and running the tires at lower pressure for the softer ride. I run the tires high and the A/C only when it's stupid hot. We both ran the cheapest gas available and I probably average 5-10 MPH faster average driving than he did and have more hilly terrain. His traffic on average was probably only a little shittier than mine. His cold starts were usually 80+ degrees, mine much lower, and I've seen a big mileage difference in driving a cold engine vs. warm.

    Living in Florida as well as mountains are two extremes compared to most of the country. I'm guessing that if someone took the time to analyze MPG differences across the country we'd find that driving in either extreme reduces fuel efficiency.

    And speedos are rarely accurate at any point within a tire's life. Around here we have a few radar speed indicators that show your speed as you drive by and none of my speedos have been right. Most read on the high side and some by up to about 10% on completely stock vehicles.

    here is the key - ethanol free gas - it's pretty much impossibly to find that around here, would be great.

    A lot of those are wrong too.

    The set coming back from the Barstow area on I-15 read 5+ higher than actual.

    Likely intentional, trying to slow down the Vegas traffic returning. I've never seen a Caltrans speed sign THAT far off before.

    Haha, I wish.. Maybe then my supra would do better than 18mpg.

    And maybe my LT4 would get more than 4mpg.

    Everyone should mention if its a 2WD or 4WD, I think thats the huge difference. No way my 4wd double cab can see 20mpg
