Biofuels are redefining the way we think about our cars and our environment and with higher ethanol-blended fuel more frequently becoming an option at the pump, we think it’s time for Merriam-Webster to update the dictionary and recognize E15 as a word!


We know what you’re thinking: how can we get a word like E15 added to the dictionary?

Well, just for perspective – here are just a few words that have been added to Merriam-Webster’s dictionary so far this year:

  • Woo-woo
  • Word-salad
  • Bingewatch
  • Humblebrag
  • Weaksauce
  • Froyo
  • Face palm
  • IPA
  • Photobomb
  • And so many more

If these words can earn a spot in the dictionary, E15 certainly deserves one!

And making the request is easier than you think. You can help make it happen by signing our petition to submit E15 as an addition here, and by posting to Facebook and Twitter to make sure Merriam-Webster knows we mean business.


E15 is changing our air, improving our engines and driving a better future. It’s time to define it.

Let’s make a difference and officially add E15 to Merriam-Webster!
