Fuel specification
The fuel must comply with national and international standards for commercially supplied fuels, such as:
EN 590 (with nationally adapted environmental and cold requirements)
ASTM D 975 No 1-D and 2-D.
JIS KK 2204
Sulfur content: Complying with legal requirements in each country.
Low density fuel (urban diesel in Sweden and city diesel in Finland) can cause a loss of up to 5% of power and an
increase in fuel consumption of about 2-3%.
