The U.S. Environmental Protection Agency said the emergency waiver allows summer sales of E15, which renewable fuel groups say can cost 27 cents less a gallon than gasoline with 10% ethanol, called E10.The EPA says E15 can be used in flexible-fuel vehicles, as well as 2001 and newer cars, light-du…

What percent is 87 octane? 87 is 10%e and 88 is 15%e?

I looked up e88 and the source said that is is called that because 84 octane unleaded gasoline is mixed with 15% ethanol to produce 88 octane. The terminology is a little confusing because it doesn’t refer to ethanol content. Still, several gas stations around me use that terminology. [imag…

Boy is it ever getting confusing. E15 is 85% gas. E10 is 90%gas, but e85 or 88 is 85% ethanol. When I’m on a trip I have to study the pumps pretty good to figure out what it actually is. We have enough trouble with diesel in gas. This is just ridiculous for the general public. My wife was at a…

[image] bing: Boy is it ever getting confusing. E15 is 85% gas. E10 is 90%gas, but e85 or 88 is 85% ethanol. Ethanol percentage and octane are two different numbers. Both are clearly labeled in my experience. I’m afraid I don’t see why that’s particularly confusing.

[image] bing: Boy is it ever getting confusing. E15 is 85% gas. E10 is 90%gas, but e85 or 88 is 85% ethanol. What’s so hard ? E10 = 10% ethanol E15 = 15% ethanol E85 = 85% ethanol

[image] texases: The confusing thing is if any companies call E15 “e88”. Stupid thing to do. I can’t find anyone calling it E88, Lots of places calling it “Unleaded 88” which is E85 with an octane rating of 88

I have been running alcohol free gas in all my small engines and it is a game changer. I wouldn’t do it any other way. Sealed tanks on cars are probably fine with E15, especially if run on a frequent basis. I wouldn’t want it in something that doesn’t get used for a winter or whatever.

[image] Nevada_545: E10 has been the standard gasoline blend in California for the last 25 years. Not disputing your claim, but there’s no mention of this on the gas pumps. Excepting one station, there is a sticker on the gas pumps there which says appx 10% ethanol. Prices a little lower th…
