Some cars need premium gas, but most don't. Yes putting in high grade gas can give you a little extra boost but it comes at a cost. Many gas stations discount the regular gas and up the price of the mid and premium grade gas.
Next you can benefit by filling up your car at the coolest part of the day. Gas expands in heat so when it is colder you get more gas for the same price.
Last, Premium gas still has a good use for most of us. I fill my tank with premium every 3000 or so miles. The higher grade gas burns hotter and can help clean out your fuel system. I have seen this work with catalytic converters that are starting to go bad. Filling with premium can clean them out a little and extend the life for a little.
Hope everyone has a great weekend!
