Product description

BY MECACYL 300ml diesel engine decontamination additive is a top-of-the-range treatment specially designed for roadworthiness testing , to avoid costly retesting due to a failed anti-pollution test.
It completely cleans and decontaminates theair circuit (turbo, EGR valve, FAP, catalytic converters) and the fuel circuit( combustionchambers, valves, pumps, injectors) by removing gum, varnish, scale and carbon deposits. It is particularly effective on the opening vanes of variable-geometry turbos.
As a result, it reduces pollutant emissions and restores optimal operation of the engine. What's more, its properties, derived from Mecacyl hyper-lubricant technology, enable it to lubricate and protect mechanical parts fromfouling.

Dosage : 1 bottle of 300ml for a 40 to 70L tank.
Frequency of use: every 30000km or before MOT.

Advantages:
- Eliminates clogging of the air circuit (turbo, EGR, FAP, catalytic converters).
- Removes soot, unburnt particles and gum from the fuel system (chambers, valves, pumps, injectors).
- Restores optimum engine performance.
- Reduces pollutant emissions.
- Makes it easier to pass anti-pollution roadworthiness tests.
- Avoids costly retesting.
- Reduces fuel consumption.
- Safe for DPFS and catalytic converters.
- Compatible with all dieselinjection systems, with or without turbo.

Directions for use :
- Pour the bottle into the fuel tank via the filler neck before filling up with diesel.
- Drive until you run out of fuel.
- Refuel as usual.
- For exclusive injector cleaning, use Mecacyl HJD2 hyper-lubricant diesel injector cleaner for roadworthiness testing (reference UD10233).

As a preventive measure before roadworthiness tests:
- Pour the bottle into the fuel tank via the filler neck before filling up with diesel.
- Run the engine at idle for 30 minutes.
- Drive for 20-30km at high engine speed (3500rpm minimum).
- Then drive normally until the fuel is completely consumed.
- Refuel before passing the technical inspection.

Please observe the usual precautions.
