Does high octane fuel have less ethanol?
In terms of its octane rating, ethanol has a rating of 113. As mentioned above, fuels with a higher octane rating reduce engine knocking and perform better. So the higher the ethanol content, the higher the octane. The octane rating for E15 (15\% ethanol) is 88 octane and E85 (85\% ethanol) is 108 octane.

Is non-ethanol gas better for cars?
Pure gas gives drivers better mileage. This is because gas mixtures like E10 and E15 have less free energy due to the added ethanol. Compared to regular and premium gas mixtures, non-ethanol gas is better for your overall mileage.
Premium gas doesn’t provide any more power or contain better additives than regular gas, and it contains the same amount of ethanol as other grades. It just resists detonation (knock) better than lower-octane gas—nothing more, nothing less. If so, keep using 89-octane to regain some power and save your engine.
