Regular Vs. Premium Fuel: What’s the Difference?

 

Whether or not you need to use premium fuel in your Mazda car is dependent on a lot of different factors. Many drivers near Columbia, MD are confused when it comes to differences in types of gasoline and wonder if using a different one than their vehicle recommends will increase performance or cause harm to your car. Here at Heritage Mazda Catonsville, our team of Mazda dealers are here to help advise you on when it’s right to use each type of fuel.

When you’re at the gas station in your 2018 Mazda CX-9 or other new Mazda car, you’ll likely see three different types of fuel: regular, mid-grade, and premium. The difference between these types of gasoline has to do with the octane level (87 for regular, 89 for mid-grade, and 91 to 93 for premium). The octane level of gasoline determines how likely it is for engine combustion to occur at the wrong time. Gasoline with a higher octane level is less likely to combust at the wrong time. These mistimed combustion events are known as knocks or pings, and if your engine suffers too many of these, it can cause long-term damage.

If you’re not sure whether your vehicle requires premium fuel, the best way to check is to look in the instruction manual or underneath the gas cap. If your car requires premium fuel, then it’s necessary to put premium in it in order to avoid engine knocks and the subsequent engine damage. However, if your vehicle recommends it rather than requires it, regular fuel should suffice. You may notice small differences in fuel economy and horsepower, though.
