Rislone® 4744-4PK DPF Clean™ Diesel DPF, Exhaust & Emissions System Cleaner, 16.9 oz, 4-Pack

Rislone DPF CLEAN Diesel DPF, Exhaust & Emissions System Cleaner has high-performing detergents and heavy duty cleaning solvents that effectively scrub and remove contaminants, soot, carbon build-up, and oily residue from the fuel injectors, combustion chambers, turbo, EGR, diesel oxidation catalyst, diesel particulate filter and the exhaust system. These along with other active chemical agents, react with the gases created in the combustion process to remove the remaining inorganic deposits. This process restores their function and with regular use maintains efficiency. As fuel is burned, contaminating byproducts are created that are circulated throughout various vehicle systems. These systems are designed to be able to handle this process during most normal engine operation. However, the use of poor quality fuel, short driving distance, cold weather, improper maintenance, and component failure can greatly increase the amount of contamination and deposits created inside these systems. Such factors can cause increased exhaust emissions, reduced fuel economy, lost power & performance, drivability issues, engine overheating, hard starts, check engine light illumination and premature engine wear. NOTE: This bottle is designed to work in ALL diesel tanks including those with misfuelling devices. INSTRUCTIONS: Light Duty Diesel (up to 40 gallon fuel tank), add entire bottle into approximately 1/4 full tank truck or large SUV, (1/2 full tank for car or small to mid-size SUV) of diesel fuel. Drive vehicle (ideally in a lower gear than you normally would) for 20 to 30 miles. Continue to drive vehicle normally and fill tank with diesel fuel. For vehicles with extremely dirty filters, a force regeneration may now be initiated. If light is still on, second application may be required, or mechanical attention is needed. Medium and Heavy Duty Diesel (40 to 80 gallon tank) use 1.5 bottles. 81 gallons and larger use 2 bottles.

• Increases power, performance, mileage and saves fuel by not only cleaning the entire emissions & exhaust system, but the fuel system too.
• Regular use every 5,000 miles tunes-up the fuel, emissions and exhaust system keeping clean and prevents excessive exhaust regeneration and the CEL light from returning. Clears P242F & Other OBD Codes.
• Will not void manufacturer’s new vehicle warranty. Specifically designed and safe to use on vehicles with DOC catalytic converters, DPF particulate filters, SCR selective catalytic reduction devices, or DEF systems.
• Works with all ULSD (Ultra Low Sulfur Diesel), regular diesel–off road for USA, biodiesel blends B2, B5, B20, DI (Direct Injected), common rail – another name for DI, IDI (Indirect Injected), TDI (Turbo Direct Injected), and turbocharged engines.
• Lowers ignition temperature inside DPF to burn soot and particulate matter, ideal for infrequent highway regeneration intervals.
