I've seen where some (Nomad and Rick360 come to mind) are running 93 octane unleaded gas mixed with leaded race gas? From what I understand, there's little to no unleaded gas around now that doesn't contain at least 10% ETHANOL so I'm wondering what effect this would/will have on engines that run this mix. :-k

I've been running straight 93 for a year or so now. I've had no problems.

I always ran straight 92 octane unleaded in the 414. The 383 that was in the Camaro I ran a mix of 92 octane and race gas (10:1 mix), but that was back a few years and was probably before the full change to ethanol here in Missouri.

I imagine the small amount of ethanol in pump gas will be insignificant when mixing with race gas. And some marinas are starting to keep fuel without ethanol mixed in, you might check there. A little more expensive...

I run a 50/50 mix in my 11.5-1 412sbc but I use the non ethanol and it seems to work fine. The non ethanol runs about $.30 more than super.

The following website contains a list of stations that carry ethanol-free gasoline:

Other than not knowing the exact mix that you're going to have it really shouldn't be an issue, but the pure gas link above works really well. I have a number of stations by me where I get my non ethanol fuels for running in my toys.

nope, this fuel is haphazard in boats.. i have been rebuilding so many carbs that i purchased a sonic cleaner to clean carbs i have also been cleaning injectors in it.

I have a co, that steam cleans fuel tanks for me on older boats with scaled tanks that the ethanol starts descaling and clogging fuel systems..

their are many diffrent problems caused by ethanol in boats each one has to be aproached diffrently..

I have a couple of offshore boats that run to maryland to fuel up..

Great link! The place listed there up above Reading Pa has a nice explanation of how they're getting the good stuff.
Headed north in NY state there were pumps not labelled - maybe E 0.

All the pump fuel here is marked "Up to 10% Ethanol". It was my impression that is the maximum they are allowed to mix in. How is it measured, tested, regulated I don't know. Maybe with congress failing to subsidize the ethanol the percentage will go down.

So its probably not more than 10% corn. But that still doesn't helps you know exactly what you got in the tank.

I'm a bit late to this party but doesnt anyone remember that you cant mix alcohols with leaded fuel? If you guys are mixing E10 etc with leaded racing fuel then your reacting the aromatics in the leaded fuel and basically killing it. You will finish up with lower detonation resistance.
You can mix straight gasoline unleaded fuels with race fuels to lower cost if you wish but dont do it with ethanol fuels
