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.
Key Features:
- Raises Cetane Numbers: Boosts ignition quality for quicker starts, smoother acceleration, and more complete combustion—especially in cold weather.
- Cleans & Protects Injectors: Keeps injectors clean and removes existing deposits for better spray patterns and fuel efficiency.
- Reduces Emissions Up to 42%: Independently tested using opacity methods—cleaner fuel burns mean cleaner air.
- Minimizes Wear from ULSD: Reduces abrasive injector and pump wear by up to 26%, countering the low-lubricity of ultra-low sulfur diesel fuel.
- Winter Formula Available: Improves cold flow and prevents gelling during cold starts and sub-freezing operation.
