Wynns Formula Gold Diesel System Treatment (76401) is a 500ml all-round treatment for diesel engines, for drivers who want to see less black smoke from the exhaust, use less fuel and win back some lost performance. It is the diesel partner of Wynns Formula Gold Petrol System Treatment.

Good to know

What causes black smoke? Fuel not burning fully, often from dirty or worn injectors, a blocked air filter, or a turbo or EGR fault; a treatment helps when deposits are to blame.
How do I use it? With the engine off, pour it in just before filling up with diesel, then drive normally through the tankful; the bottle label gives the dose.
Is it the right Wynns diesel product for me? For general upkeep, yes; for a car facing the MOT smoke test or a blocked DPF, Wynns' pre-emission and DPF treatments are aimed at those jobs.

Which one?

For the MOT smoke test, Wynns Diesel Pre Emission Test Treatment – 500ml (35392A); for a blocked filter, Wynns DPF Regenerator – 500ml (28392A); the petrol version is Wynns Formula Gold Petrol System Treatment – 500ml (70701A).
