Diesel Fuel Conditioner - RE19

KCK RE19 Diesel System Conditioner

Ultimate Diesel Injector Cleaner. Cetane Booster. Biocide. Fuel Stabilizer. One bottle. Infinite benefits.

Top Benefits — Front and Centre:

Cleans Injectors FAST
Advanced detergent chemistry blasts away carbon and internal diesel injector deposits (IDID) in as little as one tank. Restores lost power, smooths idle, and boosts throttle response—without risking damage to modern systems.

Euro 5 & Euro 6 Compatible – No Compromise
Modern high-pressure common rail systems are ultra-sensitive. RE19 is specifically formulated to clean and protect next-gen Euro 5 and Euro 6 injectors—where other additives fail or do more harm than good.

Boosts Cetane by up to 8 Points
More efficient combustion. Easier cold starts. Lower emissions. Less knock. More torque. Better driveability. Enough said.

Eliminates Diesel Bug
RE19 includes a high-potency biocide to kill microbial growth like Hormoconis resinae ("diesel bug")—a leading cause of fuel tank sludge, filter clogging, and fuel degradation.

Disperses Water 
Water in diesel = injector damage. Our dispersant chemistry breaks water into micro-droplets that are safely burned off in combustion.

Reduces Emissions, Increases Efficiency
Cleaner fuel systems + better atomization = reduced particulates, lower NOx, and significantly improved fuel economy.

Safe for All Diesel Engines
Perfect for cars, trucks, 4WDs, commercial fleets, agricultural and mining machinery, marine diesels—even long-term fuel storage tanks. One solution. Every application.

World-Class Testing. Proven Performance. No Gimmicks.

RE19 passes the same brutal industry-standard tests the OEMs use to qualify their own fuels:

• ✅ Peugeot DW10 & XUD9 Clean-Up and Keep-Clean

• ✅ Cummins L10 Injector Deposit Clean-Up & Prevention

• ✅ BMW 10,000-Mile IVD Test

• ✅ Meets EPA Section 211L (Clean Air Act)

Most additives say they clean. RE19 proves it—restoring injector flow to >95% in one tank.

The KCK Difference — Performance, Backed by Chemistry

Most diesel additives are weak, outdated, or designed for older engine tech. RE19 is a  Australian-formulated powerhouse, engineered with hybrid detergent–dispersant–fluidizer chemistry to:

• Fully clean and prevent internal diesel injector deposits (IDID)

• Restore peak fuel economy and engine response

• Prevent power loss in ultra-high-pressure injection systems

• Protect modern Euro 5 & 6 emission equipment like DPFs and EGRs

• Work in real-world conditions, with real-world results

This is not another diluted bottle of snake oil. This is precision chemistry that outperforms anything else in its class—especially in today's demanding engine platforms.

How to Use It

🛢 One-Tank Clean-Up:
Add 500mL of RE19 to 60L of diesel (1:100 ratio) to clean even heavily fouled systems.

♻️ Ongoing Maintenance:
Add 50mL per 60L (1:1000) every fill to keep injectors, fuel pumps, and emissions systems running clean.
