142 Drivin g and OperationFuel consumptionFuel consump tion is determined und erspecific driv ing cond itions – see page 212.Special equipment increases the weight ofthe v ehicle. As a result, they can increasefuel consump tion and reduce the specifiedmax imum speed.For the first few thousand m iles /kilometres, friction between the engine andtransm ission com ponents is higher. Thisincreases fuel consumption.FuelFuel for petrol enginesNormal c om mercial high-quality fuels witha m aximum ethanol content of 5% inaccordance with DIN EN 228 are suitable(for catalytic converter see pag e 145, foroctane numbers see page 208). Thequality thereof has considerable effect onthe p erformance, running and serv ice lifeof the engine. The additives mix ed with thefuel are extremely im portant. For thisrea son you must only refuel with high-quality fuels containing additives.Fuels with ethanol content greater than 5%do not comply w ith DI N EN 228 a nd mustnot b e used unless the v ehicle ha s b eenspecifically develop ed a nd approved forthese fuels.Fuel with too low an octane number cancause pinking. Vauxhall cannot be heldlia ble for resulting dama ge.Petrol with a higher octane number canalways be used.Do not use 91 octane petrol in v ehicles withthe Z 16 LET 1) engine.The ignition tim ing is a utoma tica llyadjusted according to the grade of fuelused (octane number) – see page 208.Use of petrol w ith a n oc ta ne rating of 95will ensure economica l driving.For vehicles with Z 16 LET 1) engine, use of95 RO N fuel reduces p erform ance a ndtorque.Fuel for diesel engi nesDiesel engines m ust be operated only oncomm ercially av ailable diesel fuel meetingthe specifications of DIN EN 590.S ince Ja nuary 2004, some oil comp anieshave mix ed their diesel fuel with up to 5%Bio fuel (FAME = Fatty Acid Methyl Esters)like RME (Rape-Oil Methyl Ester). This is inacc orda nce with the current DIN EN 590and d oes not ha rm the fuel injectionsystem. The characteristics of a diesel fuelmix ed up with 5% Bio fuel (FAME) do notdiffer from conventional diesel fuel and donot influence the vehicle’s driveability.I mporta nt: Diesel fuel m ixed with 5% FAM Eacc ording to DI N EN 590 m ust not beconfused with 100% Bio Diesel, which is notto be used in Vauxhall eng ines.The flow and filterability of diesel fuel a retemperature-dependent.Diesel fuels w ith improved low temp eratureproperties are therefore a vailable on thema rk et during the winter months. Makesure that y ou fill the tank with winter fuelbefore the start of the cold weatherseason.Additives can be used with diesel fuels withwinter prop erties that are guaranteed bythe manufa cturer and when using dieselfuel filters that are heated depending onthe outside temperature.Diesel fuels must not be diluted with fuelsthat are intended for petrol eng ines.1) Sales d esigna tion – s ee p a ge 208.
