    I'm new to the forum and Iv only had my 2015 Tundra SR5 for about 3 weeks. Love the truck. Had a SC 2008 Tacoma before the tundra. I want to SC the Tundra one of these days and need to make sure I'm not FFV. I don't have a yellow fuel cap and can't find anything saying FFV. Is there any other for sure way to find out. The salesman at the dealership didn't know either.

    Usually it is printed on the fuel cap. Color doesn't matter. Mine is black and says E85/gasoline.
    The fact your sales guy didn't know and more importantly didn't find out for you... time for a new guy next time around.

    A little of this and a little of that.
    Agree with Utah, get a new sales guy! Sean is right though, just run the VIN #

    Yeah the sales guy also didn't know what TSS on the back of the truck meant either. I really didn't care cuz I new I could figure this out later. The truck was low miles, 25k. Leather seats, nav, 20 inch wheels with 185/55-20 tires, Very clean. My fuel cap doesn't say FFV nor can I find it anywhere else. I'll run the vin

    From what I've found out regular unleaded gets the best gas mileage but the e85 burns cleaner and is much cheaper. I just dont like being dependent on foreign oil all the time. And the e85 ethenol and all blends is made here in the us.i run e85 about half the time.

    Actually the gas sold here is good old USA dino. We export oil now. #1producer of oil. Not dependent on foreign any more for the time being anyway.

    Cool... come on back..

    Corn is for food. For every gallon of ethanol produced there is a net loss of 54,000 BTU's. Not a very efficient process. That's why ethanol production is heavily subsidized with tax payer $$$

    Government propping up the market for corn growers with subsidies when we should be growing food if were starting trade wars.
