Premium Gasoline

While the difference between premium and regular gas matters when it comes to filling up at Addison gas stations, both share similar qualities like the fact that they are produced from crude oil and are combustible.

Regular Unleaded Gasoline

Unleaded gasoline is safer for the environment and the drivers’ health than gas containing lead.

Comparing Premium and Regular Gas

• Engine Suitability: Engines that have lower compression ratios are better equipped for regular unleaded gas as it burns faster than premium gas. Vehicles with a higher compression ratio in their engine will benefit from premium gasoline. 
• Price: You’re sure to notice the price difference of premium gas vs. regular unleaded gas at the pumps around Glendale Heights. There can be as much as a 20 to 40 cent difference between the two with premium being the more expensive option.

When debating whether to fill up with premium or regular gasoline, take note of some to these tips:

• Fueling up with premium gas when your vehicle doesn’t require it doesn’t improve vehicle performance or longevity.
• Typically, vehicles that require premium gas won’t be harmed by using regular gas, however, it’s best to use premium gas if engine knocking is heard. 
• Vehicles that utilize turbochargers may find it necessary to use premium gas.
