Thank you. ------------------------------------------------------------------------ 98 is pretty high for a non-hi perf car. Somestimes, what they used to do back then was specify "research" octane, which is usually a couple of points higher than the octane you buy at the pumps. The rating you see today is the avareage of research and motor (I think that's the name) octane. My suggestion as to what kind of gas to buy is: both. I usually mix leaded and unleaded in a 1:4 or 1:2 ratio. The unleaded premium gives me octane, the lead in the leaded protects and lubricates the valves. I've heard it said that mixing gas in this manner also gives you more octane than the unleaded premium alone, but I can't attest to that. Try it! Rei Shinozuka ihnp4!cmcl2!acf4!hkr4627
