And although you probably know this if you're serious about purchasing any of this stuff, for those who don't, with regular (non-ethanol/methanol/alcohol) fuels, the octane rating is the number given (e,g, 108, 114, etc.) whereas with Ethanol the number is the percent of ethanol in the blend. So E85 is 85% ethanol whereas E98 is 98% ethanol. The octane rating of E85 is usually given to be between 100-110 and for E98, between 120-130.

The beauty of buying ethanol-based fuels this way (vs. at a pump) besides the price discount is that you know you're getting 85% (or 98%) ethanol fuel EVERY time. We don't deal with it here since we can't get E85 at the pumps, but they can call it E85 with as little as 70% ethanol in it, which is typically what it dips down to for 'winter blends' at gas stations in the States, due to ethanols poor cold-startability. This can be enough of a variance to cause blown motors if not accounted for. Don't need to worry about that with this stuff
