I hope this question is in the correct sub forum, if not sorry. I heard that the Government is going to or has approved E-15 Gas Blend to help “Ease” gas prices and set to be delivered starting June 1st. My question is, will this blend damage our engine? I know currently most gas contains up to 10% ethanol and considering our engine is not Flex Fuel rated just wanted to ask y’all.

E-15 Gasoline?
- Thread starter Big Dummy
- Start date
My local Kum & Go has 83, 87, 91, E15 and E85 all at the same pump/every pump. You should tune if you want to run higher than E15. I currently run the 91 octane tune from ZFG, which allows you to run up to E30, which I usually do by mixing 12 gallons of 91 with 6 gallons of E85 (70% Ethanol).

Absolutely but stop thinking about things logically and focus on what they want you to.
Ethanol has lower energy content than gasoline. The reason people run e85 is that lower energy content is less likely to detonate, allowing more timing, etc. This also allows you to dump more fuel in, cooling the system, and providing more bang for your air. On the flip side, your fuel economy takes a MAJOR hit.

E15 means more ethanol and less gasoline.
Technically since ethanol has lower energy density, it raises the octane rating of the fuel, so an E15 93 is actually a lower quality fuel than an E10 93 or an E0 93.
Youll really only notice the difference in fuel economy though, as the knock resistance is what matters for power. As long as you can flow enough fuel, preventing knock is the name of the game for power. You will however, make more power for the amount of fuel used with lower ethanol content.
Long story short, E15 and 93 octane are not necessarily mutually exclusive.
