BOOST COMBUSTION, CLEAN INJECTORS, FIGHT DIESEL DEPOSITS
SWEPCO 501 Premium Diesel Fuel Improver is a powerful multi-function additive designed to restore performance and protect today's diesel engines—especially when running low-quality or ultra-low sulfur diesel fuels. It increases cetane for smoother, quieter combustion, reduces emissions, and protects injectors from wear and fouling. Whether you're managing over-the-road trucks, agricultural equipment, or off-road fleets, SWEPCO 501 keeps your diesel systems cleaner, longer, and running more efficiently.
