Xenum In & Out Diesel Power Cleaner

Xenum In & Out Diesel is a 1.5-litre professional-grade treatment for the fuel and exhaust system of diesel engines.

The product is based on Xenum's Nexgen™ technology, which acts as a fuel-borne catalyst and cleans the engine with a dual action (Double Field of Action) – on both the fuel and exhaust side at the same time.

Features

• Cleans the entire fuel and injection system from the tank to the combustion chamber
• Cleans the diesel particulate filter (DPF), catalytic converter and turbocharger vanes (VNT)
• No disassembly required – added directly to the fuel tank
• Suitable for both preventive use and problem-solving
• Suitable for all diesel engines, including those fitted with DPF and catalytic converter systems

How does In & Out Diesel work?

• IN (Fuel system): Cleans the tank, high-pressure pump, injectors and fuel lines of accumulated deposits.
• OUT (Exhaust system & DPF): Acts as a fuel-borne catalyst that lowers the soot combustion temperature from around 600 °C to around 400 °C. This helps the diesel particulate filter (DPF), catalytic converter and turbocharger vanes clean themselves while driving.

Why choose this product?

• Supports DPF function: A lower combustion temperature helps regeneration even in situations where short trips or cold weather would otherwise prevent the exhaust from reaching a high enough temperature.
• Cleans the turbocharger: Removes soot build-up from the turbo vanes.
• May improve fuel economy: A clean injection system and open exhaust support the engine's efficiency. Running often becomes smoother and smoke is reduced.
• Reduces emissions: Helps keep the exhaust system clean, which lowers harmful emissions.

Instructions for use (intensive treatment)

1. Pour the full contents of the 1.5-litre bottle into a fuel tank that is as empty as possible.
2. Fill the tank with 20–40 litres of diesel.
3. Drive under heavy load and at more than 3000 rpm for several kilometres, so the exhaust system and turbo heat up enough to start the cleaning reaction.
4. Repeat the previous step several times if needed.

Suitable for all diesel engines, including the latest generation fitted with a diesel particulate filter (DPF) and catalytic converter.
