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

 


One of the best things about the new 2018 lineup of Toyota vehicles is how fuel-efficient they are. Whether you’re buying a 2018 Toyota Camry sedan or a 2018 Toyota RAV4 SUV, you can be sure that you won’t be needing to make many trips to the gas station. But at the end of the days, you still will need to gas every so often, and many drivers near Ellicott City, MD are left wondering about the differences between regular and premium fuel. Here’s a quick primer about when you need to get regular and when you need premium.



The simple explanation of the difference between regular and premium gasoline is that premium gasoline has a higher octane level than regular gasoline. The typical octane level for regular is 87, while the typical octane for premium ranges from 91 to 93. The octane level of gasoline determines how likely it is for engine combustion to occur at the wrong time. Higher levels of octane make it less likely that combustion will occur any time besides when it is supposed to occur. This mis-timed combustion is known as engine knock, because the sound it makes resembles a ping or a knock.



Now, just because premium fuel is higher octane doesn’t necessarily mean it will deliver better performance. In fact, unless your car’s manual specifically states for high-octane premium fuel to be used, there won’t be any performance differences between premium and regular fuel. Some vehicles will recommend premium gasoline rather than requiring it. In this case, the best thing to do is test out both types of fuel to determine if there are differences in performance of fuel-efficiency.
