What’s the difference?

The main differences are the cost as well as the octane levels within the gasoline. Premium gasoline has higher levels of octane which produce a better, cleaner burn for your engine. Some types of higher octane gasoline are required in specific vehicles due to, engine performance, fuel economy and engine maintenance. There is also a mid level gasoline that has a octane level of 89, not many vehicles need to use this grade of gas, if anything, just a handful of vehicles. The lowest grade is the regular gasoline which is most used in the majority of average cars. The owner’s manual of a vehicle also actually lists the types of gas it is required to have, making it easy for you to see which is the correct type of fuel required for your vehicle.

What is “Regular”? 

Regular gasoline has an octane rating of 87. Most vehicles use this as a standard gasoline where it would be an average gas for the average vehicle. Since it is the most used and has a lesser quality than other higher levels, it is also the cheapest in comparison to the higher levels. It’s usually 10 – 15 cents cheaper than premium gas. Regular gas is also easier to locate around the world in more remote areas compared to its higher priced comparisons.

What is “Premium”?

Premium gasoline is a higher octane level than regular gasoline, resting at either 91 or 93 depending on if there is “super premium” available. With a high octane level in your gasoline, you get a clean burn from your gas to your engine which makes your engine burn fuel more efficiently. The higher level provides the engine with better performance and much better wear compared to regular gasoline. Although, most engines do not require the high octane and priced gasoline to perform. It is only specific vehicles that need premium gas to run how it was designed to.

Which to you get?

The main factors to consider is the price gap and the type of engine. The price of premium fuel is significantly higher than regular fuel and provides only some better fuel efficiency in some vehicles engines. In most cases there is no real advantage to get premium gas for an average vehicle that does not require it. While on the other hand, for a vehicle that requires the higher grade, it is better to give it what it needs than fueling up with a lower grade that can damage the performance ,fuel economy of engine and even have it make a knocking noise.


Can you switch?

It’s better to have a lower performing engine use a higher octane gas level instead of a higher performing engine with regular gas. When the high performing engine is given regular gas, the quality goes down. Think of it like a horse, an average horse can be fed regular and better carrots. But, when a high quality horse is fed just regular carrots, the high quality of horse goes down.
