All-Purpose Diesel
Performance Additive
Reduce manual regeneration (regens), maximize power, decrease maintenance and downtime, and extend the life of your equipment with our flagship Optimum Performance Technology-Advanced Detergent (OPT-AD ) fuel additive. It offers year-round performance, keeping your fuel injectors clean and maintaining seamless flow through all critical fuel delivery systems.
Cold Weather Fuel
Performance Additive
Don’t let freezing temperatures bring your operations to a halt. Our Optimum Performance Technology Cold Flow Improver (OPT-CFI) offers the full benefits of our all-purpose additive while preventing gelling, keeping your filters clean, and setting a new standard in cold-weather performance.
Gasoline Engine
Performance Additive
Our Optimum Performance Technology Gasoline Engine Additive (OPT GA) meets the demands of modern direct-injection gasoline engines while delivering exceptional performance in traditional port-fuel-injection systems. OPT GA is designed to protect gasoline, particularly ethanol blends, from phase separation, gum formation, and other fuel instability issues that can occur when gasoline comes into contact with moisture during storage.

Our strategically located analytical labs will test your fuel to identify potential issues such as contamination, water, microbial growth, or degradation, which can lead to costly downtime, performance and efficiency issues, and regulatory compliance challenges.

“With our heating oil additive, HeatDoc™, we are able to stabilize the fuel over a long period of time—that’s the time of year when the heating system isn’t being used—call it April to October. During this time, moisture can come from the outside into the tank. By stabilizing the fuel with HeatDoc™, we’re able to ensure when the burner finally calls for oil, they have a good quality fuel. Fuel quality is not an issue for us anymore.”
— Mark Brideau – President, Brideau Energy
“We are excited to expand our relationship with AFS from the construction fueling industry to the waterways. Delivering our customers the highest quality marine diesel and gasoline possible is our joint goal.”
— Rick Workman – President, Taylor Oil
“AFS continues to be a critical partner in the success of my business. Back in 1990, when we first experienced fuel-related challenges with outside tanks, they personally stepped forward to help solve the problem and educate me on the critical issue of fuel quality.”
— Charlie Ugiletto – President, Cubby Oil Company.
“With AFS fuel conditioners, we keep our fleet on the road profitably. It’s important to have 24/7 access to high-quality fuel conditioners, testing, and lab services.”
— Kris Lee, Weaver Energy, Lilitz, PA
“We have had very good results using the AFS fuel additives at several locations now. We have been able to double the life of fuel filters, which pays for the product. In addition, we are conservatively seeing a .5% improvement in better fuel mileage. With AFS working with our local fuel suppliers, the results are good. In addition, while it is still early, we seem to have a reduction in fuel-related issues on the newer EPA engines.”
— Fleet Maintenance Manager of a 500+ Power Unit Agricultural Organization
“We’ve been working with AFS for three decades. Paul and his team are extremely knowledgeable about additives—they’re always educating and innovating—but really it’s the energy, enthusiasm, and proactive approach to service that set this strategic partner apart from all others. We feel we couldn’t do better with any other company.”
