Pretty noticeable difference between 93 and e85 for me as well.

Yup, 75 more hp and on less boost= less heat. Good stuff.

I don't understand why Missouri is stuck on 91, as is Oklahoma. Go a few miles south of us and plenty of 93 in Arkansas.

When you're in Springfield, you can buy 93(both E10 and E0), but at only a few stations. It's trucked in from Arkansas(instead of by pipeline to the Brookline terminal) so It's more expensive.

Don't try it, not worth it.

Pure-gas.org says that all Chevron 94 is ethanol free in BC. Is this correct?

I'm planning on a trip to the Canadian Rockies next summer, so I'm mapping out gas stations.

Ditto but I saw 91 jump way up in price. It was slightly more than ethanol 91 and now it's a buck more. Last fill was 93. 91 definitely for the 04 Harley, the KTM and the lawn mowers.

I am able to get Sunoco 110 and 100 with lead from the pump at near my house. I just filled 15 gallons of 110 on Sunday.

If you put leaded fuel in your corvette, you just killed the catalytic converters and voided the warranty on them.

Lead will make quick work of poisoning the catalytic converter. In addition more octane than required to stop detonation will do nothing for the engine or power. Now if the poster has headers without the cats, higher compression or added a blower the 110 octane may be needed!

Not to mention the warranty will be void. What a hot mess using leaded fuel.

I also run 91 and 93 octane ethanol free gasoline in my 56 and my 64(and my lawn mower). Don't put the ethanol crap in your 61(or your mower).

91 ethanol free in my supercharged Mercedes and 93 ethanol free in my C6 Z06.

Was reading an article on local news website and read this:

"Van Winkle says no matter where you get your gasoline, don't fill your tank when the station is getting its gas delivered.

"It is stirring up anything that's in the bottom of the tank and you could be picking it up and putting it in your tank," he said"

I have never thought of this but it makes sense. I always assumed the filters they use would stop this from happening.

Many years ago I read an article that discussed that problem. The article said that it takes 48 hours after the filling, for all the crap to settle back to the bottom of the tank.
