Purpose and Specifications

Rislone Complete Fuel System Cleaner is an 8-in-1 diesel fuel additive designed to improve fuel quality and engine performance. This 500 ml bottle treats up to 22 gallons of diesel fuel, making it ideal for light to medium-duty diesel vehicles, trucks, and SUVs.

What It Does:

• Cleans fuel injectors, valves, fuel lines, intake manifolds, and combustion chambers
• Boosts cetane rating for better power and acceleration
• Lubricates the complete fuel system to reduce friction and wear
• Prevents fuel gelling and degradation, extending fuel stability
• Removes water and contaminants from diesel fuel
• Fights corrosion and protects fuel system components
• Reduces black smoke and rough idle conditions

Real-World Performance: Regular use delivers an average fuel economy increase of 7.3% and 87% power recovery from cleaning effects. Engine dynamometer tests confirm improved fuel efficiency.

Compatibility: Safe for all diesel engines with catalytic converters, diesel particulate filters (DPF), and DEF systems. Works in trucks, SUVs, and passenger car diesel applications.

When to Use / Replace?

Add one 500 ml bottle to your fuel tank every 4 to 6 weeks for optimal engine efficiency and fuel economy. For vehicles with larger fuel tanks (over 22 gallons), use one bottle per 20 gallons of fuel capacity. The product works immediately upon mixing with diesel fuel—no special installation required.

Storage: Keep in a cool, dry place. Diesel fuel treated with this additive remains stable for extended periods, preventing oxidation and varnish buildup during storage.
