Permitted sulphur content in diesel
Diesel with a higher sulphur content than
500 ppm for engines with SCR systems
If diesel with a higher sulphur content than per-
mitted is used on a short-term basis, this will not
cause permanent damage to the SCR catalytic
converter. The SCR catalytic converter may,
however, require diesel with a low sulphur con-
tent for some time after this to regain its normal
efficiency.
If diesel with too high a sulphur content is used
for a prolonged period, there is a risk that the
SCR catalytic converter will not operate correct-
ly, which will result in a reduction in engine
torque.
Engine type Max. sulphur content Note
Engines without EGR and SCR
systems
4,000 ppm (0.4%) If the sulphur content is higher than
2,000 ppm, the oil change intervals
must be halved. A higher sulphur
content than 4,000 ppm is not per-
mitted, since this will result in en-
gine damage.
Engines with SCR system only 500 ppm (0.05%) A higher sulphur content than
10 ppm for Europe or 15 ppm for
the USA may only be used where
Stage III A/Tier 3 or less restrictive
emission laws apply.
Engines with both EGR and SCR
systems
350 ppm (0.035%) A higher sulphur content than
10 ppm for Europe or 15 ppm for
the USA may only be used where
Stage III A/Tier 3 or less restrictive
emission laws apply.
