Premium fuel really better for your luxury vehicle?

High-octane gas isn't necessarily better than regular grade. It isn't somehow more pure and it doesn't go through a superior refining process. It doesn't even keep your engine cleaner, as some people seem to believe. Premium fuel is just gas that contains a mixture of hydrocarbons that are slightly less combustible than those found in lower octane gas. This might seem odd, since cars use internal combustion engines that rely on the combustibility of gasoline to make them go. So, why would you pay extra money for gas that doesn't ignite quite as well as less expensive gas?
