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.

Performance Benefits:

  • Improves ignition quality in any diesel fuel
  • Improves fuel economy and reduces fuel-related maintenance
  • Reduces smoking, misfiring, knocking, and starting issues
  • Extends injector and pump life significantly
  • Enhances fuel storage stability and system cleanliness

For 99 Integra
Size: 12 Fl Oz (Pack of 1)
I have not seen this one that was sent in a black bottle, anywhere else. It does state for Honda & Acura. I have a 1999 Acura Integra and was using the (Honda) genuine power steering fluid in the silver bottle with a blue cap. So, just taking off one star because i haven't used it yet. Seals seeping on rack & pinion, so using just to top it off every now & then.
