TOP TIER™ Cleans For You

Best Gas
Guarantee

Simonson sells only TOP TIER™ gasoline to help keep your car on the road.

Not All Gas is Created Equal

All gas is created at the same refineries; however, what separates Simonson gas from the rest, is that we provide you with gas that has detergent additives. These detergent additives, that actively clean your engine while you drive, is what makes Simonson fuel TOP TIER™.

Cleans Your Engine While You Drive

You’re engine was not designed to operate dirty. TOP TIER™ is a fuel quality program created and enforced by automakers for optimal vehicle performance.

Fuel

Better fuel at a better price

At Simonson, we want you to get the best gas to keep your car on the road. Fuels with lower-quality additive packages can build up deposits on fuel injectors and on intake valves. Others can build up deposits in combustion chambers and may lead to intake valve sticking. These lower levels of additives can have negative impacts on engine performance and vehicle responsiveness. That’s why choosing Simonson’s TOP TIER™ gas is the only way to go.

Benefits of TOP TIER™

Better Than Regulation

Ten top automakers have raised the bar. TOP TIER™ Detergent Gasoline helps drivers avoid gasoline which may leave deposits on critical engine parts, reducing engine performance and in some cases, engine damage. That’s something drivers and automakers can get behind.

Superior Gas

Simonson delivers TOP TIER™ gasoline in every drop that we sell. That means no matter which store you are at, or what grade you select, you are getting a better gas than you will find elsewhere. That means your car gets a tune up every time you fill up at a Simonson Station Store.
