Wynns Catalytic Converter & Oxygen Sensor Cleaner (25692) is a 500ml treatment for petrol and petrol hybrid engines that works on two parts at once: the catalytic converter and the lambda, or oxygen, sensors. Keeping both clean holds the air-fuel ratio where it should be, cuts emissions and helps head off engine warning lights, especially on cars used around town.

Good to know

• Why does a dirty oxygen sensor matter? The sensor reads the exhaust so the engine management can correct the fuel mixture; when it is contaminated the mixture drifts, fuel use and emissions rise, and a warning light can follow.
• Is it for my hybrid? Yes, if it is a petrol hybrid: it is listed for petrol and petrol hybrid engines, and it is not one for diesels.
• Will it clear a warning light that is already on? Read the fault code first; if it points to a failed sensor or a damaged converter, the part needs replacing, as no additive will repair it.
