Wynns Pre-emissions Test Treatment for Diesel Engines (31964B) is a 325ml single dose for the MOT smoke test, added to at least 30 litres of diesel. It suits all diesel and diesel hybrid engines on fuel up to B30, and cleans the injectors, the diesel oxidation catalyst and the particulate filter to bring smoke and soot down.

Good to know

• How much fuel should be in the tank? At least 30 litres of diesel for the whole bottle; it usually goes in just before filling up so the fresh fuel mixes it through, but follow the label.
• When should it go in? Plan for roughly 150 km of driving between treating the tank and the MOT, including a longer run, so the cleaner reaches the exhaust.
• What if the diesel is badly smoking? It can help one near the limit, but heavy black smoke usually means a fault such as a worn injector, a blocked air filter, or a turbo or EGR problem.

For a bigger 500ml dose that can also be used every third tank, Wynns Diesel Pre Emission Test Treatment – 500ml (35392A); for petrol, Wynns Petrol Pre Emission Test Treatment – 500ml (35792B).
