Fuel for petrol engines

Only use unleaded fuel that complies with DIN EN 228. Fuels with ethanol content greater than 5 % may only be used if the vehicle has been specifically developed and approved for these fuels.

Use fuel with the recommended octane rating. Use of fuel with too low an octane rating can reduce engine power and torque and slightly increases fuel consumption.

Caution:
Use of fuel with too low an octane rating could lead to uncontrolled combustion and engine damage.

Fuel for diesel engines

Only use diesel fuel that complies with DIN EN 590. The fuel must have low sulphur content (max. 50 ppm). Equivalent standardised fuels with a biodiesel (= FAME according to EN14214) content of max. 7 % by volume (like DIN 51628 or equivalent standards) may be used. Do not use marine diesel oils, heating oils or entirely or partially plant-based diesel fuels, such as rape seed oil or bio diesel, Aquazole and similar diesel-water emulsions. Diesel fuels must not be diluted with fuels for petrol engines.

The flow and filterability of diesel fuel are temperature-dependent. When temperatures are low, refuel with diesel fuel with guaranteed winter properties.
