    Does .75mpg increase even cover the additional cost of ethanol free fuel? I know you said it was cheaper in Utah but it doesn't even come close for me here in TN. It's nearly .75 more per gallon.

    No I didn't count that. Locally I'm getting ethanol free for the same price as premium so I don't even consider the cost.

    Yeah doesn't seem worth it. Premium is a dollar more than regular here. Only $2.19 for 87 right now.

    Maybe it isn't worth it for you. I think my truck calls for at least 87 octane (our mid grade) and premium (our 89) is generally .10-.15 more. I'm getting ethanol free for $2-3 more per tank than mid grade. The fact that it runs better is enough for me to justify that. The extra mpg just gives me some money back from that $2-3 extra cost.

    Our mid grade is around $2.55 and our premium is around $2.70

    Ah that makes sense. Crazy that the difference between grades is so little. If that were the case here I would opt for premium.

    I took my 2016 Tundra 1794 edition in for the 30K mile service, only did half because of the Cost. Well, I was getting 15 in town, but now I'm getting 13, they did something to my computer to probably make me come back where I won't. Getting a programmer that hopefully I can get my old truck back.

    Yeah I'm not sure why. I'm wondering if it has to do with our local production being geared that way or something. We have a ton of off highway stuff so maybe all that higher octane is demanded there. For as long as I remember it's been about 15 cents between grades or something like that.

    93 octane ethanol free gas will give youI a better gas mileage. I went from 325 miles (using 89 octane Ethan free gas) to 365 on a full thank (26 gallon), 2 mpg increase. '17 5.7 FFV CREW MAX SR5. My stock tires are 275/65R18. I've a TRD dual exhaus.
    If you look at your owner's manual it will tell you that it's ok to use 87 octane (because of advance timing) but to research for 91 octane or higher.

    Marine industry strictly provide non ethanol fuel at docks to customers for good reason. It's non debatable as to why, they know what fuel provides engine longevity and getting your rear end back to shore.

    However, if your sputtering around in town and to another town in a vehicle not cared about, cheap fuel in a POS vehicle match...Any ethanol % fuel works for you hands down!

    Jet maf, hi flow drop in dry filter, DD 12 hole injectors. That combination will improve fuel economy but not by much

    Definitely not worth it here. I run in my boat because of the 95 gallon tank and it can sit for a while.

    That is because lots of boats are not designed for ethanol. Vehicles are. Plus as I stated in previous post gas can sit in a boat for a while. Ethanol in fuel can attract moisture and separate sitting. In a modern vehicle that is run regularly there are no issues

    I get the same mileage with my 07 4.7L DC 4X4 as my 02 Ford Excursion 2WD with 7.3L diesel and only if I drive the Tundra like a granny.

    I believe swapping out the clutch fan for a electric unit would help

    After driving a Tacoma for the past 15+ years, I really can't complain about my Tundra's fuel mileage. Honest to say 90% of my driving is around town, short trips between 15-20 miles to and from. And every time I park my truck it shows me getting anywhere from 16.5 to 19.2 MPG. I haven't really checked it at the pump yet with a calculator, and don't really care to. I'm pretty well content with what I get from this Beast of a truck.

    The boat motors that can't burn ethanol fuel are as ancient as vehicles that can't burn ethanol fuel.
    I didn't read what you stated in previous post, but bottom line is non ethanol gas burns cleaner than ethanol fuel. Thus, less carbon build up. I seen the difference between usage of the two fuels at a friends shop who does nothing but outboard rebuilds. That's why those that know use non ethanol in their outboards, and why I add same into this ole trucks tank all the time.

    That set up gets good hay mileage. Don't need to have extra hay.

    Well, I usually get 18-20 mpg on long trips and around 15 around town.

    Things done include changing the input ( thing that is in the fender) to the stock airbox to TRD, new muffler and exhaust, trd air filter, beast mode, and nominally 36 psi in the tires. I did put in ethanol free gas when. Found it and was getting 18.7 ish MPG in 4 we on the highway. I thought that was pretty good.

    Ps. 2018 Sequoia.
