Best Gas Mileage - You Can Save Over $200 Per Year By Switching Grades of Gas!

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?

It will cost you $208.00 annually if you fill your car with premium gas instead of regular. The difference between regular fuel and premium fuel is about twenty cents per gallon. Therefore it will cost you $4.00 more per tank if you use premium gasoline instead of regular gasoline. This assumes you have a 20 gallon tank and you fill up about once per week.

Looking at the higher octane question of increased fuel economy, does it help? The bottom line answer is emphatically no!! High octane premium gas does not increase fuel economy one bit. The octane rating is a number that has nothing to do with how efficient it is in creating energy to run your engine.

The octane rating is a measurement of the proportion of isooctane to heptane in fuel. In non technical terms it is a rating that grades how much energy it takes to ignite that fuel. The rating has nothing to do with how much energy the gas puts out.It has absolutely nothing to do with fuel economy.

The next question, does premium gas make your car gain performance, does it run better? The answer is the same as the fuel economy answer, no!! It has been shown that there is no significant difference in the way your car runs if you use premium gasoline.

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.

Car manufacturers utilize this slight horsepower gain to market their cars claiming more horsepower by optimizing and designing their cars to take advantage of higher octane premium gasoline's anti-knock properties. Engineers and car experts agree that if you opt to use regular gasoline in your car designed for premium gasoline, the loss of horsepower is so small, you will not be able to detect any difference.

Will you harm your car or void your warranty if your car manufacturer recommends that you use high octane gas? Most automakers say using regular gas even when your owner's guide says to use premium gas won't void the warranty. Most automakers also say that using regular will not damage the engine.

Next time you go to fill up try regular instead of premium. You will immediately save $4.00. See how your car performs with the regular. If it runs fine and you don't hear any knocking continue to use regular. You could save $200.00 per year!
