The Octane Rating of E15

The Octane Rating of E15

Consumers are starting to see a new fuel available when the pull up to the pump. E15, which is gasoline with 15% ethanol is growing in popularity, especially in the Midwest. The fuel is approved for all cars 2001 and newer.

What drivers may not realize is the gasoline they currently use has 10% ethanol in it. That’s E10, the regular 87 octane you can buy today. Adding five percent more ethanol increases the E15 octane rating. This is because ethanol has the highest octane rating of any component in gasoline.

Currently most retailers are passing the value of E15 to the consumer with both a superior fuel and a less expensive price at an 88 or 89 octane.  So the consumer is enjoying better engine performance, no mileage loss, lower emissions, and more money in their wallet. The retailers are doing this by utilizing blender pumps that typically mix E85 and E10 to dispense E15. If the retailer does not have a blender pump, they will pick E15 up at the terminal and truck it to their underground tank and dispense it directly.
