Gas companies and auto makers love it when you buy premium gas.  They like it so much that they try to perpetuate myths about high octane fuel. Myths like premium gasoline will lead to better fuel economy.  Myths like premium gas will make your car perform better.  Why do the oil companies and auto makers like high octane so much?

Gasoline refiners and retailers like high octane fuel because it’s a lot more profitable for them than regular. You pay 20 cents more for premium gas while the retailer only pays about 8 cents more for that same gallon. That means the retailer makes an extra 12 cents on every gallon of high octane fuel he sells.

The refineries  take in a few cents per gallon more on premium than on regular when they sell to distributors. When you realize that the few cents per gallon is multiplied by the tens of thousand of gallons of gas that refineries sell, you can see that it adds up to a lot of extra profit.

The gasoline refineries and retailers are not the only ones that make more money from high octane fuel.  Auto makers use premium gas to add to their profits too.  One way they do that is by creating a higher perceived value for their cars. 

If a car has to have high octane gasoline it must have a more expensive engine therefore the car must cost more.  Using that logic the car companies can get higher prices on some models by recommending only high octane fuel can be used in those models. This adds credibility to their contention that the car is worth more money.

Another benefit of premium fuel that auto makers capitalize on is to take advantage of the anti-knock properties of high octane gas.  By designing engines to be optimized for that property of high octane fuel they can create engines that in fact do get more horsepower out of high octane gasoline then out of regular.

Since there is some horsepower gain it allows the car makers to advertise higher horsepower ratings for their engines. Again, higher horsepower ratings means more expensive car which means more profit for the auto makers. 

These optimized for premium engines actually do put out a little more horsepower on high octane gasoline than with regular.  But most car experts and engineers seem to agree that if you use regular in a premium engine, the difference in horsepower is so small, you probably can’t tell.

High octane gas does not increase fuel economy.  Regular fuel can be run in a so called premium engine without any noticeable effect.  In the end it all comes down to money.  By convincing you that you need to use premium gasoline they are able to take more money out of your pocket and put it in theirs.
