What Is the True Difference Between Regular and Premium Gas?

What Are The Differences

There’s a lot of talk among drivers about the differences between regular and premium fuel. While your car might require premium, both types of fuel are considered equally efficient, depending on the type of car you’re driving.


To make sure you know exactly what type of fuel your car needs, you have to first check your car’s manual, which is something that is taught at when taking driving lessons Denver instructors offer. That way, you have a clear picture of whether the vehicle was designed to work on regular or premium fuel.


The most obvious difference between the two is the cost. While regular gas doesn’t cost that much, premium gas – as the name would suggest – is far more expensive. So, is there any real value behind this increase in price?


Well, the most important technical difference between premium and regular fuel is that premium fuel comes with a higher octane level. This means that it basically won’t pre-ignite that easily, since it can withstand a greater degree of compression prior to ignition. Typically, high performance engines that require higher octane fuel will perform more efficiently.


Nevertheless, while higher octane fuel can increase the performance of some vehicles, that doesn’t go both ways. If you own a high performance vehicle and you want to save cash by adding lower octane fuel, it’s important to avoid that, since it could effectively damage the engine.
