BARDAHL 166031 - 5-IN-1 DIESEL CLEANER 500 ML

Bardahl 5-in-1 Diesel Cleaner (code 166031) is a concentrated multifunctional additive for cleaning the fuel system of diesel engines. With a single 500 ml bottle it cleans injectors and pump, valves, turbo, EGR valve, diesel particulate filter (DPF/FAP) and catalytic converter, with no disassembly. It can be used preventively or as a cure and is compatible with all diesel engines, old and new generation. It is designed for drivers who want to restore their diesel's performance and for workshops looking for a complete cleaning treatment to offer their customers.

What it is for

The 5-in-1 Diesel Cleaner is indicated when the vehicle shows these symptoms:

• excessive fuel consumption;
• loss of power;
• the vehicle "doesn't drive as it should", but the reason is unclear.

According to Bardahl, the cause may be clogging of the turbo, EGR valve, particulate filter, valves and catalytic converter. The product works on all these components in a single treatment.

Benefits

• ✅ Injectors: cleans and protects the whole injection system (injectors and pump) and restores regular fuel atomisation.
• ✅ Catalytic converter and DPF: helps prevent particulate filter clogging, even in city driving.
• ✅ Turbo: counters turbo fouling, keeping performance and power efficient.
• ✅ Valves: deep valve cleaning for optimal compression and combustion.
• ✅ EGR valve: removes deposits and sludge, supporting correct combustion and lower emissions.
• ✅ Limits excessive fuel consumption and increases power and performance.
• ✅ Helps avoid replacing expensive components.
• ✅ Reduces polluting emissions and helps pass the emissions inspection.
• ✅ No disassembly: poured straight into the tank.

Directions for use

1. Wait until the fuel reserve warning light comes on.
2. Pour the whole 500 ml bottle into the tank and add 20 litres of diesel.
3. With the engine warm, drive for 20 minutes at a steady 2,500-3,000 rpm, then return to normal driving.
4. Repeat this 1 or 2 times until the treated fuel is used up, over one or more trips.

Frequency recommended by Bardahl: one treatment every 5,000-10,000 km (shorter interval for mainly urban use).

Frequently asked questions

What is Bardahl 5-in-1 Diesel Cleaner 166031?
It is a concentrated 500 ml additive added to diesel to clean, in a single treatment, the injectors and pump, valves, turbo, EGR valve, diesel particulate filter (DPF) and catalytic converter, with no disassembly.

What are the 5 functions of the 5-in-1 Diesel Cleaner?
According to Bardahl the product works on five areas: injectors, catalytic converter and DPF, turbo, valves and EGR valve.

How much diesel does one 500 ml bottle treat?
One 500 ml bottle is poured into the tank when it is on reserve, then 20 litres of diesel are added.

How often should I use the 5-in-1 Diesel Cleaner?
Bardahl recommends one treatment every 5,000-10,000 km, with the shorter interval for drivers who mainly drive in town.

Why drive at 2,500-3,000 rpm after adding it?

What is the difference from the Bardahl Diesel Injector Cleaner (COD 122)?
The Diesel Injector Cleaner (500 ml in 20 litres, every 5,000 km or before the emissions check) focuses on the injectors and diesel pump. The 5-in-1 Diesel Cleaner, besides injectors and pump, also works on valves, turbo, EGR valve, DPF and catalytic converter: it is the choice for a complete engine clean.
