If anyone is going on an ethanol run for the upcoming season let me know. I'd be in for barrel.

I will be running e85 this year. Where do you buy a barrel in town?

Sorry if this was answered in the 15 pages previous! ha

This.

Hopefully I'll be converted to e85 by this weekend. My injectors get here today, then data logging tunes. Hopefully be ready for SCT this weekend.

I know this site is pretty dead, but this may help out some that are still linked to it.

Informative thread where a chemist tests the E85 “Goo” and explains what he thinks it is.

In a nut shell it’s in the fuel, not the lines tanks etc like so many believe. It’s basically an additive that’s gas station specific and or old additives ”gum” that has accumulated in old tanks that they filled with ethanol. This also explains why some areas have “goo” while others do not.

It will not clog fuel pumps, injectors, filters etc as it is soluble in its liquid E85 state. As the ethanol/gas mixture exits the injector the additive crashes out of the mixture and builds up in the intake/injector tips etc. After a hot engine is shut down and fuel slowly dribbles out of the injectors due to the system being pressurized the gas and ethanol evaporate and the “goo” crashes out of the mixture and builds up on injector tips. This may also explain why I haven’t seen much in the way of goo on my current car. I run no check valve in the fuel system. When I shut the car down pressure instantly drops to zero and I get no leakage past the inj tips. I also believe injector design/atomization and leakage all play a big roll.

The chemist in the thread suggests a 15% addition of race fuel and or toluene/xylene should be enough to break down the sticky gum formation and “clean” the goo away. So about 2 gallons of race fuel per 12 gallon tank should solve the problem. He suggested 100 octane unleaded race fuel. Seems like this would be a pretty cheap and easy solution to me.

That's interesting. I have yet to see this goo on my setup.

Interesting. I've been planning on running the carb defender additive in mine to try to fight this.

Agreed, I have only used pump e85 from quik shop in maize and after this stuff sitting in my fuel system for 3 years everything worked properly. No clogged or stuck injectors either.. BTW maize e85 has been dead on every time I have tested

It won't get stuck in the injectors or anywhere in the fuel system pre-injector. It crashes out of the mixture post injector. Still think alot has to do with injector design and if your injectors leak after shut down.

So maize is at 85% ethanol? Thats great to hear, last year I tested them many times and they were about 75%. Same as the petro america I go to. I haven't been out to maize this year.
