A fuel system and engine cleaning agent that is poured straight into the fuel tank; nothing has to be removed from the engine. The supplier describes it as a three-way catalytic cleaner containing cleaning agents, corrosion inhibitors and propellants, intended to remove carbon deposits from the fuel system and help the engine run more cleanly.
Options: 1, 2 or 3 bottles
Use: unscrew the lid, tear off the seal and pour the bottle into the fuel tank
The listing does not state the bottle size, the dose per tank or whether it suits petrol, diesel or both, so check the listing details and the label before using it in your car.
Practical tip: add the cleaner just before you fill up so it mixes with a full tank of fuel, then drive the car normally for a longer run rather than short trips. Smoky or rough running is one of the emissions checks at the MOT, so clean the system well before the test; see our pre-MOT checklist.
