You will be perfectly fine between 94 and 93 octane, so don't worry. The only problem that may occur is the fact that octane ratings of gasoline marked "premium" or "regular" is not consistent across the country.<P>One state may require a minimum octane rating of 92 for all premium gasoline, while another may allow 90 octane to be called premium. To make sure you know what you’re buying, check the octane rating on the yellow sticker on the gas pump instead of relying on the "premium" or "regular", names.<P>-Drew
