Fuel consumption, fuel, refuelling90Fuel consumption,fuel, refuellingFuel consumptionFuel consumption is determined underspecific driving conditions.Fitting special equipment will increase theweight of the vehicle. This in turn increasesfuel consumption and reduces thespecified maximum speed of the vehicle.For the first few thousand miles /kilometres, friction between the engine andtransmission components is higher. Thisincreases fuel consumption.Fuel for diesel enginesDiesel engines must be operated only oncommercially available diesel fuel meetingthe specifications of DIN EN 590.Since January 2004, some oil companieshave mixed their diesel fuel with up to 5%Bio fuel (FAME = Fatty Acid Methyl Esters)like RME (Rape-Oil Methyl Ester). This is inaccordance with the current DIN EN 590and does not harm the fuel injectionsystem. The characteristics of a diesel fuelmixed up with 5% Bio fuel (FAME) do notdiffer from conventional diesel fuel and donot influence the vehicle’s driveability.Important: Diesel fuel mixed with 5% FAMEaccording to DIN EN 590 must not beconfused with 100% Bio Diesel, which is notto be used in Vauxhall engines.The flow and filterability of diesel fuel aretemperature-dependent.Diesel fuels with improved low temperatureproperties are therefore available on themarket during the winter months. Makesure that you fill the tank with winter fuelbefore the start of the cold weatherseason.Additives can be used with diesel fuels withwinter properties that are guaranteed bythe manufacturer and when using dieselfuel filters that are heated depending onthe outside temperature.Diesel fuels must not be diluted with fuelsthat are intended for petrol engines.Fuel consumption ............................... 90Fuel for diesel engines........................ 90Refuelling............................................. 91Fuel cut-off device 3 .......................... 91
