Fuel system
Fuel specification
The fuel must at least satisfy national and internatio-
nal standards for market fuel, for example:
EN 590 (with nationally adjusted environmental and
temperature
requirements)
ASTM-D975-No. 1-D, 2-D
JIS KK 2204
Sulfur content: According to legal requirements in
each respective country. If the sulfur content ex-
ceeds 0.5 percent by weight oil change intervals
must be changed, see “Lubrication system”.
Note that low-density fuel (urban diesel in Sweden
and citydiesel in Finland) can cause a power reduc-
tion of approximately 5% and a decrease in fuel eco-
nomy of approximately 2–3%.
Only use fuel of the recommended grade according to the fuel specification below. Always make sure to maintain
a high level of cleanliness when fueling and when working with the fuel system.
All work involving the engine’s unit injectors must be performed by an authorized service location.
WARNING! Risk of fire. Work on the fuel system must be performed on a cold engine. Fuel leakage and
spillage onto hot surfaces or electrical components can cause a fire. Store fuel-soaked rags in a fire-safe
manner.
