What Are All the Gas Types at the Fuel Pump?

Updated: Aug 6, 2021

When you pull up at the gas station to fill up your tank, you’ve probably noticed that there are several different types for you to choose from. Like most people, you probably just go with regular, unleaded gas, but should you be using premium? What are the benefits? What does it all mean? Today we’re going to take a look at the different types of gas and what they can do for your vehicle.

What Are Your Options?

At any typical gas station, you’ll see “regular”, a med-grade “plus”, and “premium” gas options with three different price tags. Along with their descriptors, you will also see numbers that indicate their octane rating. Regular is usually around 87, plus is approaching 90, and premium is in the low 90’s. The octane rating of the gasoline informs its resistance to withstand compression without spontaneously combusting. This is an important resistance, as it will keep your engine from “knocking”.

What Does it Mean to Have “Knocking” in Your Engine?

When you have “knocking” in your engine, there are multiple detonation points within your engine’s cylinder and these multiple explosions will create an audible sound, hence the name. As the fuel burns unevenly, your car will emit unfortunate noises and even suffer potential damages if left unattended. If you’ve been hearing a knocking sound from your car, bring it into our Automotive Repair Shop in Gaithersburg, Maryland.

It All Depends on the Car You Drive

Though there are several different factors and problems that can lead to engine knocking, one of them is the type of fuel you’re using. Some vehicles were designed to be fed with high octane fuel, so check your owner’s manual and see what the manufacturer recommends. However, if your knocking problem persists longer than a few gas station visits, then it may be a different issue, so make sure to get it checked out by professionals.

Should I Upgrade to Premium Fuel?

Unless your vehicle needs it, there is no real reason to upgrade. Though higher-grade gas has a better fuel economy, its high cost offsets any real value for the average driver. However, if your owner’s manual recommends or requires you to use a higher octane fuel, then you should make the switch if you haven’t already. Your engine will thank you.
