Purpose and Specifications

Rislone Diesel DPF Exhaust & Emission System Cleaner is a powerful 425 ml treatment that scrubs soot, carbon, and oily buildup from your diesel engine's fuel injectors, combustion chambers, turbo, EGR valve, DPF filter, and exhaust system. It restores lost power and performance, reduces frequent DPF regeneration cycles, improves fuel economy, and clears check engine lights like P242F codes. Use it in all modern diesels including trucks, SUVs, and cars with DOC, DPF, SCR, or DEF systems - safe and won't void your warranty.

• One bottle cleans the entire fuel, exhaust, and emissions system for better mileage and smoother running.
• Active regeneration accelerator lowers DPF soot burn temperature for easier cleaning without long highway drives.
• Proven in ULSD, biodiesel, common rail, turbo, and direct-injected engines.
• Regular use every 5,000 miles (8,000 km) prevents clogs and extends DPF life up to years longer.

When to Use / Replace?

Add this cleaner when you notice reduced power, poor fuel economy, frequent DPF regens, or check engine lights from exhaust issues - especially if you drive short low-speed trips without highway runs. Pour the full 425 ml bottle into a nearly full tank before refueling; drive normally to let it work. No replacement needed - it's a maintenance treatment with a shelf life of 3-5 years unopened. Use every 5,000 miles to keep systems clean and avoid costly DPF repairs over $2,000.

FAQ

Will it fix a blocked DPF without a mechanic?
Yes, its heavy-duty solvents and regen catalyst unclog blocked DPFs, clear codes, and pass emissions tests - many users report check engine lights off after one use.

Is it safe for my DEF-equipped diesel truck?
Absolutely, designed specifically for SCR/DEF systems, turbo diesels, and modern emissions setups - no warranty worries.

How often should I use it?
Every 5,000 miles for prevention, or anytime symptoms like regen warnings or power loss appear.
