Does Using A Higher Octane Gas Improve Fuel Economy

 

Is higher octane gas worth the $208.00 increase in gas costs per year? Does the higher octane premium gas result in better mileage? Is better fuel economy attained by using premium gas? Does higher octane gas enable your car run better?

The cost difference between regular gas and premium is generally about twenty cents per gallon. That means filling up a 20 gallon tank will cost $4.00 more if you fill with premium instead of regular.

This octane measurement North Face Jackets For Kids does not indicate the amount of energy the gasoline produces, which would be an indicator of fuel economy. The final answer is:octane rating and increased fuel economy have no relationship whatsoever!

That said, I must throw in this one caveat, your car might perform with slightly more horsepower with premium than with regular but you would be hard pressed to notice the difference. Premium just allows car makers an extra advertising ploy.
