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.
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.
