You Might Be Asking...

Where do I get Dieselex Gold?

The product is available in bulk and at cardlock through select UFA Petroleum Agencies.

When will I notice a difference in performance?

The time to notice a difference varies depending on the mileage of your vehicle. Generally you will start to see a difference after 2-3 tanks, once the detergent properties have time to start cleaning up injectors and restoring horsepower. For newer engines, the difference will be less significant as the product will work to keep your engine clean and maintain the performance.

What happens if I have an old fuel tank?

Dieselex Gold’s detergents will begin to clean up your fuel over time. If you have an older tank that has experienced some corrosion you may find a need to replace the filter on your fuel tank as Dieselex Gold cleans up the tank and removes contaminants preventing them from getting into your engine.

How does Dieselex Gold work with biodiesel.

Dieselex Gold has been developed and thoroughly tested to up to B20.

Does Dieselex Gold affect the shelf life of the fuel?

We understand that in Agriculture fuel often sits in equipment between seasons, Dieselex Gold was designed with this in mind. The oxidation inhibitor in the product slows the oxidation process to decrease gum and deposit formation to extend fuel storage life. In addition, the stabilizing agents in the product help maintain fuel integrity.
