Fuel Quality Grade

Use commercially available diesel fuel with less than 0.5% sulfer

content. If the sulfur content is higher than 0.5%, the intervals

between oil changes should be halved e.g. change oil every 250

hours. Don’t use fuel with more than 1% sulfur!

The following fuel specifications / standards are approved:

• CENEN590orDIN/EN590(underdevelopment)

• DIN51601(Feb.1986)

• BS2869(1988):A1andA2

• ASTMD975-88:D1andD2

• NATOCodeF-54andF75

The exhaust emission levels determined during certification by

the supervising authority are always based on the reference fuel

described by law.

Winter-grade fuel

Waxing may occur at low temperatures, clogging the fuel system

and reducing engine efficiency.

If the ambient temperature is less than 0°C (+32°F), winter-grade

fuel -suitable down to -15°C (+5°F) - should be used. This fuel is

usually available from filling stations well in advance of the cold

months. Diesel fuel containing additives (Super Diesel) is often

on sale as well, for use down to -20°C (-4°F).
