I run no ethanol Car Gas in my O-200A Citabria. I add 4 Oz of marvil mystery oil per 10 gallons. The cost savings is significant. The smell is bad. It also stains the fabric worse than AvGas. My plane is mostly white. No ethanol gas is available about 3 miles from the airport. I have a truck bed mounted tank and pump which I also use for my boat so it's easy. Else if it were a lot of trouble I would just use 100LL.
Hello All,
I'm shopping for a 7GCBC and have one picked out I think will work. My last airplane, a Super Cub, had a 150hp O-320 that had a mogas STC. The Citabria at which I'm looking has a 160hp O-320 (higher compression cylinders). Is there a mogas STC available for this engine?

Take a look at the web site: pure-gas.org and select your state to find a list of locations to buy "off-road" gas which does not contain ethanol. This gas is less expensive because it is free of all highway tax.
Some airports have "Auto Gas" or "Mogas" pumps with off-road gas available to pump directly into your STC approved aircraft. I find these airports are often crop duster strips where the operator is using off-road gas for his airplanes. No credit card machine, just pay in cash to the owner.
Also look for locations that sell "off-road" gas to the construction industry, racers, farmers, and boaters. When I had my Citabria, I would take several 5 gallon cans to a local farm supply store and buy 88 E0 gasoline. Then use a small electric pump to transfer the fuel into the wing tanks. Thus no lifting or balancing the 5 gallon cans above the wing on a step ladder.
One of our airport residents has a 1000 gallon tank and gets 89 octane "off-road" gasoline delivered by truck for $3.14 a gallon. He lets his friends fill up their airplanes, or gas cans, for $3.25 a gallon which pays for the electricity to run the pump and maintenance to the pump, filter, meter, etc.
