Purpose and Specifications
The 3RG 88261 Fuel Additive is a 1-liter diesel treatment designed specifically for soot and particulate filter regeneration in diesel engines. It lowers the ignition temperature of soot, helping your DPF (Diesel Particulate Filter) burn off accumulated particles more effectively during normal driving, preventing clogs and keeping exhaust emissions clean.
This mid-class additive from 3RG extends the life of your particulate filter by promoting active regeneration, reducing backpressure for smoother power delivery and better fuel efficiency. Use one 1-liter bottle to treat up to 400 liters of diesel fuel, ideal for cars, vans, and trucks operating in everyday conditions from -20°C to 40°C.
- Triggers DPF regeneration every 500-1000 km of driving
- Shelf life: 3 years unopened, 1 year after opening
- Compatible with all modern diesel engines including those with ULSD fuel
When to Use / Replace?
Add 3RG 88261 when your dashboard shows DPF warning lights, during long motorway drives (over 30 minutes at highway speeds), or every 10,000 km / 6 months for preventive maintenance. It's especially useful in city driving where short trips prevent natural regeneration.
Replace the additive treatment every 20,000 km or annually to maintain filter health and avoid costly DPF replacements that can run thousands. Safe for use year-round, but double dose in winter below 0°C for optimal soot burn-off.
