Where can you get gas for your classic car?

Answer 1

Well, that would depend on which classic car we are talking about. More specifically, which engine we are talking about. Compression ratio, is the key, here. There are many options. First, there is aviation fuel. This is not really advised for street driving. However, most of your smaller airfields will put it into a can for you. Or, you would have to trailer the car in. Reason being, there is no road tax on their gas, so, off road use only. There are two types. Use the lower octane rating, and about 20%, ONLY. The octane rating on this fuel varies by altitude, so if in Denver, it will be higher, than say, Seattle. Now, this ios for something built in the mid, to late 60's, with 11:1 compression, or higher. Most towns will have a gas station somewhere in the shadows, that sells a race fuel, of some sort. Be carefull. More octane than you need will foul your plugs, load up at stop lights, and just run bad, all the way around. Now, this brings us to pump fuel issues. The problem here, is simply hardened valva seats. Pump fuel is unleaded. The purpose for lead in the fuel is to lubricate the valves. A quick valve job, removing the cylinder heads, and installing "false," or hardened valve seats, is the best answer. It will not de-value your hot rod, at all. Then, if you mix regular, and premium together, larger portion being regular, believe it or not, will up the octane rating a small amount. This is a trick we found in the later 70's, and it works. I cannot explain how, or why, but it would always allow 2, to 4 degrees more advance, in the timing, without "ping," or detonation. Remember your state smog laws, as if you run H&H, or Moroso race fuel, or aviation fuel, they have lead. Lead will destroy your catalytic converter, thus killing performance, and, costing you a huge fine.......Chuck.....
