    I've got a 2011 Tundra with the flex fuel badge. I've always heard not to run E85, but now I see a lot of E88 gas out there. Can anyone tell me if this is OK to run in my truck? Thanks

    Won’t hurt your engine, if that’s what you are asking.

    Lower gas mileage, so shorter range. Decreased mileage may or may not be offset by lower price of the higher ethanol blends. Have not seen any real-time tests or calculations to see where break even point between mileage & price is. Plus, with the constant fluctuations in prices, would need a calculator or spreadsheet to figure it out each time.

    Constant use requires more frequent oil changes but check your owners manual for specifics for your year.

    I’m running e85 in my 03 Tundra. It works well and makes a lot more power.

    I think I read it’s like 20-30% reduction in fuel economy... so if it’s >20-30% cheaper, it’s a better deal tank for tank... but then you calculate in the more frequent oil changes... and if there are any other trade offs...

    I’ll stick to costco’s top tier blend of mid grade for now :)

    I have the same badge and I ran the mid-grade for a while and didn't really notice anything other than a delay when stomping on it. Then I switched to NO Ethanol based full and I liked the power, but I still had the delay off the line. Switched to e85 gas and over the next few tanks I noticed the delay was gone. Performed a Gumout intake treatment and now she flies off the line. I do have to change the oil more often, but it's worth it when you want to get on it.

    I know it's an old thread, but I was looking for anyone else running Sheetz brand e88. I use it in my FFV 12 CM. I also run it in my 18 3500 Chevy work van. I swear it runs better than standard 87 octane. I really have no hard evidence to prove it. I'm about to pull my 6k lb trailer through the mountains and I've got 46 gallons of 88 in the tank. I guess we will see!

    Does the check engine light go off sooner or do you just track your mileage? I ran E85 for 2 months straight just to seen how the truck ran and what kind of mileage I got.
