the no ethanol price is about 50% more than the regular, but the octane is up,, Oh! E85 (85% ethanol) is 108 octane.
3 gal of e85 +7 gal 93 =97.5 octane or maybe 98.1,,,,counting the 10%
3 gal of e85 + 7 gal of 91 = 96.1,,, or maybe 96.5 counting the 10%
3gal of e85 + 7 gal 89 =94.7 or maybe 95 counting the 10%
maybe you can do your own math and put in the octane you want.
The more ethanol you have in your Crossfire engine the less MPG you get, the octane rating may be higher but that is of little use when the compression ratio is fixed.
If you wanted to save money on gas costs you should have purchased a smaller car with a smaller engine. Maybe you would be better of on the Prius forum. 😜 Surely the highest MPG can be got using 100% gasoline.
The more ethanol in the fuel the more damage can be done to components not designed for high ethanol blends.
What ratio of ethanol to gas is the most efficient for our cars? I for one prefer no ethanol, burning a fuel lower in latent power seems a waste of time to me.
Ethanol use is good for farmers income and bad for countries where corn is a staple in their diet, due to the higher prices.
