15% Ethanol

[Jaeger]

I wish I could get ethanol-free regular gas, but locally about the only way to avoid corn juice is to go premium.

E85 (85% Ethanol) requires special fuel system components. It absolutely will damage most cars that are not FLEX FUEL certified.

E15 (15% Ethanol) is the new blend under discussion. EPA is touting this as safe for all cars, but several manufacturers are saying that using E15 may harm the car, and may void the warranty in the event it causes harm.

as long as you have a more powerful fuel pump with larger injectors and the car is retuned, there is absolutely no damage caused by running the fuel.
