I live in California and we have already approved e15 sales. Thankfully, most stations are not outfitted to pump it yet, but in about a year's time we will be seeing e15 at our pumps. What do I do/add to the fuel for my 1990 CRX to prevent damage? Even though I pump 91 octane I'm still not safe/future proof. I fear they'll use higher ethanol content to reach that same octane level and I'm basically f*****. Replacing all the relevant seals and rubber components is somewhat of a tall task at the moment.
