Purpose and Specifications

STP Diesel Injector Cleaner is a powerful fuel additive designed specifically for diesel engines. This 200ml bottle cleans dirty fuel injectors by dissolving harmful deposits like carbon, gum, and varnish that build up over time. Add one bottle to your fuel tank for a full clean with just one tankful, restoring lost power, smoothing rough idling, and improving acceleration. You'll often notice better performance after just 80 km of driving, with reduced fuel use and lower exhaust emissions for a more efficient engine.

Safe for all diesel fuel systems, it protects injectors and helps extend engine life. Use every 6,000 km or at oil changes to keep your diesel running strong, especially in modern common-rail engines sensitive to deposits.

When to Use / Replace?

• Use if you notice rough idling, sluggish acceleration, hard starts, or higher fuel consumption – common signs of dirty injectors after 75,000+ km.
• Ideal for preventative maintenance every 6,000 km or 6 months to avoid buildup and reduce DPF regens.
• Shelf life is typically 3-5 years when stored in a cool, dry place away from extreme temps (best between 0°C and 30°C).
