Land Rover Discovery Owners & Service Manuals

Land Rover Discovery: Diesel engined vehicles

Use only high quality diesel fuel, according to EN590 or equivalent.

These vehicles are capable of running with up to a 7% blend of bio-diesel, in accordance with the European Standard EN590. It is not recommended to use a higher blend of bio-diesel.

The quality and specification of diesel fuel varies significantly, depending on geographical location. It is recommended to use a premium fuel, or the highest quality of fuel available.

High quality fuel promotes a longer life for your engine components. Lower grade fuel contains higher levels of sulphur, which is detrimental to engine components. If low quality fuel is used, light coloured smoke may be evident at the exhaust.

Prolonged use of additives is not recommended. Do not add paraffin or petrol to diesel fuels.

  • If you inadvertently fill the fuel tank with petrol instead of diesel, do not attempt to start the engine. Contact a Retailer/Authorised Repairer immediately.
  • Any damage caused by running the vehicle with fuel other than those stipulated, will not be covered by the vehicle's warranty.

SULPHUR CONTENT

  • If this vehicle is equipped with a Diesel Particulate Filter (DPF) exhaust after treatment system, the maximum sulphur content of the fuel must not exceed 0.005% (50 parts per million), in accordance with EN590-EU4, or World Wide Fuel Charter (WWFC) Cat 3.
  • The sulphur content of diesel fuel used in vehicles not fitted with a DPF, should not exceed 0.3% (3 000 parts per million).

In some countries, diesel fuel may contain higher levels of sulphur, which will require reduced service intervals to reduce the effects on the engine, and the exhaust after treatment components. If in doubt, contact a Retailer/Authorised Repairer for advice.

Using an incorrect specification of fuel will cause serious damage to the engine and/or the exhaust after treatment system, which may not be covered by the vehicle's warranty. If in doubt, contact a Retailer/Authorised Repairer for advice.
