Padgett - Thanks for the information. I do remember people adding alcohol to their cars back in the late 40's. Some also put the alcohol in the radiator for anti-freeze, but that's a whole other issue. We must be around the same age to remember some of this stuff! I've been using Shell 93 octane and hoping it will not rust my gas tank. I live in Northern Kentucky and we are having a cold winter so far. As a result, my Crossfire is sitting outside, under a cover, in the cold. Unfortunately, I do not have a garage. That's why I'm seeking all the information on fuels that I can gather to protect the engine as well as the gas tank.

Thanks again for the information. If there is more, please feel free to enlighten me, and probably others as well.

Jim
