Using an incorrect specification of fuel causes serious damage to the engine and the exhaust after-treatment system. The vehicle's warranty does not cover this. If in doubt, contact a retailer/authorised repairer for advice.
Most vehicles have a Diesel Particulate Filter (DPF) exhaust after-treatment system. The maximum sulphur content of the diesel fuel must not exceed 0.005% (50 parts per million). The sulphur content is in compliance with the EN590-EU4 and the World Wide Fuel Charter (WWFC Category 3 or above) standards. Failure to comply with the standards may damage engine components and the exhaust after-treatment system.
The sulphur content of diesel fuel used in vehicles without a DPF should not exceed 0.2% (2 000 parts per million) in accordance with WWFC Category 1. Fuels with higher sulphur content may damage engine components and the exhaust after-treatment system.
In some countries, diesel fuel may contain higher levels of sulphur. If used, more frequent vehicle servicing is required, to help reduce the effects on the engine and the exhaust after-treatment components. If in doubt, contact a retailer/authorised repairer for advice.
