When it comes to regular, plus, and premium gasoline, the difference lies in the level of octane. Depending on the particular vehicle you drive, your engine may require a specific type of fuel to operate efficiently and safely. Below, the gas industry experts at CMS Oil Company in Lapeer, MI, describe how these three fuel grades vary.

What Is the Difference Between Regular, Plus & Premium Gas?

Regular

Most vehicles on the market run on regular unleaded gasoline. This fuel contains 87% octane and is suitable for all kinds of automobiles, especially those with low compression engines, such as compact cars and trucks. Unless your vehicle’s service manual tells you otherwise, you can use regular unleaded gas. 

Plus

Plus gasoline is mid-grade and contains an octane level of about 89%. In conjunction with low heptane levels, this gasoline requires higher pressure to ignite. As a result, the fuel burns a bit cleaner than unleaded. If your car was manufactured more than about 20 years ago, then it probably does not have sensors to monitor and adjust the engine’s octane levels. Therefore, those in the gas industry recommend using plus fuel to maximize performance. 

Premium 

Premium gasoline has the highest octane level at about 91%. As such, it makes a great fuel for automobiles with more sensitive engines, such as classic cars, larger SUVs, and luxury vehicles. It requires tremendous pressure to combust in the reservoir, which will minimize wear and tear, preventing the need for expensive replacement parts and costly repairs.
