What’s the Difference Between Regular and Premium Gas Anyway?

For most people, the initial choice would be to put regular gas into their vehicles because it costs less, but you can’t help asking if premium gas is really worth it.  

The main difference between regular, mid-grade, and premium gasoline is the octane level.  A higher octane level contributes a more efficient burn in the combustion chamber.  When you are making your selection at the pump, you’ll notice that most gas stations offer three levels of octane which will be the large number indicated on the button:  Unleaded 87, Plus Unleaded 89, and Premium Unleaded 91-93.  The higher the octane level, the higher the price.  Premium gas does give a slightly better fuel economy however, some may argue that it’s not worth the big price gap from regular gas which typically costs about 15 to 20 cents less per gallon than premium.

When to consider premium gas

Although regular octane gas is recommended for most vehicles, your best bet is to check your owner’s manual.  There are a handful of cars with high compression engines, like sports cars and certain luxury cars, need mid-grade or premium gasoline to prevent knocking.  This would be the only time you would need to consider filling up with premium gas.

It may seem that filling up with premium gas is like giving your car a treat, but if your car doesn’t require it then it really doesn’t offer any benefit, it will only end up costing you more.  The only way to ensure your car is performing at it’s best is to keep on top of a regular car maintenance schedule.
