Never tried it but sheetz has it. I read all 01 and newer cars are fine to use it. I have a 13 Corolla, 16 accord and 19 odyssey I am thinking to start using and see. About 50 cent/ gal cheaper which is about 12% with a 2% mpg loss from what I read. Thoughts or experience?
Anyone use 88 octane e15?

My old 2014 Silverado with the Ecotec3 5.3L was flex fuel rated. I tried a few different grades, E85 and E15 stuff. All of it made the fuel mileage worse. Ethanol simply has less energy per unit volume so even though you can tweak the timing on the engine to make more horse power it simply cannot deliver as much mileage as normal gasoline for most vehicles. I could always tell when I got a "good" tank of 87 as the vehicle would just drive better and return better mileage.

I'd be surprised if the MPG loss is only 2%, I'd wager-5-10 but it may not be as much as the price difference either. Then its a question of any additional issues w/ the higher ethanol.
Reference. E15 Fuel Information - Iowa Renewable Fuels Association
- In a real-world environment, the difference in mileage between Unleaded 88 and regular gasoline is virtually undetectable. Studies by Oak Ridge National Laboratory and the National Renewable Energy Laboratory have shown that with all other things being equal, in a controlled environment, ethanol’s impact on fuel economy would be equal to the loss of energy density. This translates into a loss of less than 2% for Unleaded 88 when compared to regular gasoline. For a vehicle getting 30 mpg this would equate to a drop to around 29.4 mpg, or about the loss of miles to the gallon when vehicle tires are improperly inflated.
Nice article beyond that part too
