TOP TIER™ Licensing Program

Top Tier Program

Retailers voluntarily join the program to supply a higher standard fuel which meets the TOP TIER™ requirements focusing on the engine needs which ultimately focuses on the end customer - the vehicle owner.

The additive companies create additive formulations and conduct testing, ultimately receiving TOP TIER™ approval. The fuel retailer licensee agrees to purchase fuel treated with a TOP TIER™ additive at the correct concentration and display the logo.

Here are the six easy steps to become TOP TIER™ licensed.
