Fuel

[martyb]

So I have no gas stations near me that sell high octane, and out here in AZ our best fuel is 91 octane. What’s everyone doing for these older cars that need leaded high octane fuel? It’s an original LS6 with 11:25 compression. I don’t race it or drive it hard, but when I do jump on it every once in a while I can hear a little knock. Currently use lead additive and Torco, but not sold on that solution.

If you have a small airport by you, you could possibly buy it from them. That's what i do here in illinois.

You just fill 5 gallon cans or do you fill the car at the airport?

See if there are any drag racers living around you. Maybe you can ask them or order your fuel through them?

The way to do it is to bring 5-gallon gas can and use that. Never try to fill a car directly at an airport. The self serve pump is usually by the edge of the tarmac and you can just walk up and use your credit card right at the machine. We have a couple local commuter airports within 10 miles of my house. They have the 100 octane "low lead' which the old cars seem to love. A lot of guys also use it for gas-powered landscaping tools since the ethanol mixed fuel is really bad on them.

As for price, it is usually only around a buck more a gallon than whatever 93 octane fuel is going for at the local gas station that day.

Can you mix with normal 91 unleaded that contains ethanol?

You can, but it's the ethanol you want to avoid. You don't have non-oxy gas where you are ? Stations around me discovered there is a BIG market for it and have added pumps over the past several years.

----Get yourself a couple of 5 gallon cans of 110 octane racing fuel. When the tank is down about 5 gallons go ahead and give it 5. That should be enough. Then when you are down 10 gallons pour in the second 5 and take it back to full with 91. Unless you are driving every day this should hold you a good long time. Then repeat!
----I don't know about you but depending on where you live there can be all kinds of additives added to av-gas. Personally, I have had bad reactions with it, but others haven't. Your choice!......Bill S

Never fill a licensed road vehicle at the airport. If authorities see you they could fine you for avoiding highway taxes. Much like dyed diesel being found in licensed trucks. Always give priority to the airplanes if you have a gas can. Cloudy rainy days are always low traffic days at airports.
