Fuel - petrol
Petrol is used as fuel. Petrol must fulfil the EN 228 standard. Most engines can be run with octane ratings of 95and 98 RON. Only in exceptional casesshould 91 RON be used.
• 95 RON can be used for normal driving.
• 98 RON is recommended for optimum performance and minimum fuel consump-tion.
When driving in temperatures above +38 °C, fuel with the highest possible octane rating isrecommended for optimum performance andfuel economy.
IMPORTANT
• Always refuel with unleaded petrol so as not to damage the catalytic con-verter.
• Do not use additives not recom-mended by Volvo.

Fuel - diesel
Diesel is used as fuel. Only use diesel fuel from well-known produc- ers. Never use diesel of dubious quality. Die-sel should fulfil the EN 590 or JIS K2204standards. Diesel engines are sensitive tocontaminants in the fuel, such as excessivelyhigh volumes of sulphur particles for exam-ple. At low temperatures (-6 °C to -40 °C), a par- affin precipitate may form in the diesel fuel,which may lead to ignition problems. Specialdiesel fuel designed for low temperaturesaround freezing point is available from themajor oil companies. This fuel is less viscousat low temperatures and reduces the risk ofparaffin precipitate. The risk of condensation in the fuel tank is reduced if the tank is kept well filled. Whenrefuelling, check that the area around the fuelfiller pipe is clean. Avoid spilling fuel onto thepaintwork. Wash off any spillage with deter-gent and water.
IMPORTANT
Only ever use fuel that fulfils the European diesel standard. The sulphur content must be a maximum of 50 ppm.
IMPORTANT
Diesel type fuels that must not be used:
• Special additives
• Marine diesel fuel
• Heating oil
• FAME 15
(Fatty Acid Methyl Ester) and
vegetable oil.
These fuels do not fulfil the requirements in accordance with Volvo recommendationsand generate increased wear and enginedamage that is not covered by the Volvowarranty.
Empty tankThe design of the fuel system in a diesel engine means that if the vehicle runs out offuel, the tank may need to be vented in theworkshop in order to restart the engine afterfuelling. Once the engine has stopped due to fuel starvation, the fuel system needs a fewmoments to carry out a check. Do this beforestarting the engine, once the fuel tank hasbeen filled with diesel:
1. Insert the remote control key in the igni- tion switch and push it in to the end posi-
15Diesel fuel may contain a certain amount of FAME, but further amounts must not be added.
