Listen up, I know you pull up to the pump not really paying attention and just fill up the tank. But do you know what those numbers and fuel levels actually mean? If you’re anything like me, the answer is HECK NO! So, this week I want to help you understand what octane is, what those numbers at the pump mean, and why you should be filling up with the appropriate fuel levels! Take a look at our guide below and if you’re unsure of which level you should be using, check your owner’s manual or give us a call today!

The real difference between fuel types:

• The most obvious difference between fuel types is the price point that comes along with them. When you pull up you’ll notice that “premium” fuel is more expensive and it’s a pretty obvious difference. In fact, premium fuel usually runs about 20 cents higher than regular fuel.
• In addition to those price tags, premium fuel has a higher octane level. The numbers you see, 92, 83 and 87, indicate how much octane is in the fuel. So in order to differentiate the octane levels, premium is a higher number and regular gas has a lower number.

What is octane?

Perfect question! Octane is exactly how much compression fuel can withstand before igniting inside your engine. A higher octane fuel will not pre-ignite or explode as quickly as lower octane gas. So, it’s important to fill up with the right fuel especially if your vehicle requires premium fuel. Why? Well, let us tell you….

Every Kia model and every other model on the road is designed to take in a specific type of fuel and while it may seem like a good idea to fill up on a lower level, it’s not. Doing so could leave you with a damaged engine and a hefty repair bill in the end. If your vehicle requires premium and you choose to fill up with lower levels, that combustion we talked about earlier, will occur faster. Which in turn, could lead to issues like your engine to make knocking noises, reducing your car’s power and fuel economy, and potentially causing engine damage. Again, that means a hefty repair bill will be coming your way!

What if your vehicle requires lower levels and you choose to fill up on premium? Well, I’m here to tell you not to waste those dollars! Filling up with a higher octane fuel doesn’t have any real negative effects but it also doesn’t have any positive benefits. It’s basically neutral – so just fill up with what you’re supposed to!
