Gas thread

I'd say that your car is just starting to run shittier than it used to, and you will still see the less MPG even when summer hits.

So isn't the main problem that Ethynol provides less energy when it combusts, and also burns at a different speed than typical gasoline?

Thus that is why bikes (which require more precise air/fuel mixing and higher octane due to high rpms) don't work well with anything more than 10% ethynol?

Wouldn't running a higher-percentage ethynol blend be similar to running too low of an octane, i.e. you would get detonation and pinging?

No the ehtynol isn't effecting you. You won't find it higher than 10% in today's market. Its not truely effecting anything. Its definately not a octane thing... the ethynol itself is 103 octane so that's not it. The more you got in the higher your octane would be. Its after the ethynol is added that they add in 86 or 87 octane gas to knock the octane level back down to 93. Otherwise it would be a great deal higher when they added the ehtynol to the 93 octane gas.
