About Power Service: Diesel Expertise Since 1956

When it comes to keeping diesel engines running at their best, few names carry more authority than Power Service. Power Service is a third-generation, veteran- and family-owned company that has been at the forefront of diesel fuel additive manufacturing since 1956, built on an enduring commitment to quality, integrity, and continuous product innovation. Based in Weatherford, Texas, the brand has grown from its humble roots into America's largest manufacturer of technologically advanced diesel fuel additives.

Unlike many companies that spread their focus across dozens of product types, Power Service channels all of its energy and expertise into a single mission: treating diesel fuel. That singular focus has allowed the brand to develop one of the most comprehensive and rigorously tested diesel fuel additive lineups available anywhere, with formulas engineered to address every major challenge a diesel engine owner is likely to face — from gelled winter fuel to injector deposits to microbial contamination in the tank.

A Product Line Built Around Real-World Diesel Challenges

Power Service offers a family of purpose-built products that address distinct performance needs. Diesel Kleen +Cetane Boost is loaded with cetane, detergent, and lubricity improver to clean injectors and restore peak performance. Diesel Fuel Supplement +Cetane Boost acts as a winterizer and antigel, preventing fuel from gelling and protecting against fuel-filter icing during cold-weather months. For emergencies, Diesel 911 is a winter rescue formula designed to restore fuel flow to engines stalled by gelled fuel or frozen filters.

Beyond performance and winter protection, the brand also tackles long-term fuel tank health. Clear-Diesel Fuel & Tank Cleaner is a fuel polishing formula that removes water and slime, disperses contaminants, and stabilizes diesel during extended storage. And for operations dealing with microbial growth, Bio Kleen Diesel Fuel Biocide offers a dual-phase kill of bacteria and fungus in both the diesel fuel and water layers of a tank.

Trusted by Fleets, Farms, and Everyday Drivers Alike

Power Service products are used by some of the largest fleets in North America, as well as major construction and mining operations — industries where diesel reliability is non-negotiable. But the brand's lineup is equally relevant to the individual diesel truck driver, the farmer relying on heavy equipment through the winter, or anyone with a diesel passenger car who wants to protect their investment. Cummins Inc. has even endorsed Power Service Diesel Kleen and Diesel Fuel Supplement for their equipment lines, citing exceptional performance and improved engine longevity.

All Power Service fuel additives are formulated to be effective in biodiesel blends as well as conventional diesel, making them a versatile choice as fuel compositions continue to evolve. Whether your concern is injector cleanliness, cold-weather operability, or fuel tank hygiene, there is a Power Service formula engineered specifically for that job.
