Wynns Diesel Xtreme Cleaner — 500ml

Part Number: WYN12293

Wynns Diesel Xtreme Cleaner is a professional-strength treatment designed to restore severely contaminated diesel fuel systems. Its concentrated 500ml formula delivers maximum cleaning power with advanced detergents that dissolve stubborn deposits in injectors, pumps, valves, and combustion chambers. Ideal for vehicles with power loss, rough running, excessive smoke, or hard starting, it helps bring diesel engines back to optimal performance.

Product Characteristics

  • Maximum strength formula with high detergent concentration
  • Cleans the entire fuel system from tank to combustion chamber
  • Rapidly dissolves carbon, gum, and varnish deposits
  • Restores injector spray patterns for efficient combustion
  • Recovers significant lost horsepower and torque
  • Reduces black smoke and harmful emissions
  • Improves MPG by enhancing combustion efficiency
  • Improves cold start performance
  • Safe for common rail, direct injection, and turbo diesel systems
  • Professional grade — trusted for problem-solving applications

Storage & Shelf Life: Store sealed in a cool, dry, and well-ventilated place. Keep away from direct sunlight, freezing, and heat sources. Shelf life: 5 years from date of manufacture.

How to Use

  • Add the entire 500ml bottle to approximately 40–60 litres of diesel fuel.
  • For severe contamination, use at a higher concentration (1 bottle per 30–40 litres).
  • Preferably add to a nearly empty tank before refuelling.
  • Drive normally to allow treatment to circulate through the system.
  • Results are typically noticeable after 1/4 to 1/2 tank of treated fuel.
  • For preventative care, use every 6 months or 6,000 miles.
  • For problem-solving, a second treatment may be beneficial after the first tank.
  • Safe for vehicles with DPF and catalytic converters. For ongoing protection, follow with Wynns Xtreme Diesel or Diesel Injector Cleaner.
