E15 2018 Titan

Every once and while I fuel up and E15 is the only choice, thanks corn county. The mileage does seem to drop but does it do damage to the truck. Thanks

Manual states to use only 87 octane and no more than E10 fuel. However, Nissan is good about over-engineering and accounting for the idiot owner factor, so you’re likely OK as long as you don’t run it regularly. At any rate, the E15 was likely diluted by the remaining E10 in your tank, so it probably was E14, at worst.

Re: E15 2018 Titan

I absolutely try to avoid the stuff. Not because of performance issues but for the reasons @GoVols! stated. I will gladly pay 20-30 cents more a gallon to keep my truck running in tip-top shape.
