Diesel Permitted sulphur content in fuel Fuel with a higher sulphur content than 15 ppm for engines with SCR systems If fuel with a higher sulphur content than that specified in the standard is used on a short-term basis, this will not cause permanent damage to a catalytic converter. The catalytic converter may, however, require fuel with a low sulphur content for some time after this to regain its normal effi- ciency. If fuel with too high a sulphur content is used for a prolonged period, there is a risk that the cata- lytic converter will not operate correctly, which will result in a reduction in engine torque.

sulphur content in fuel for unaffected oil change intervals Note Engines without EGR and SCR Up to 2,000 ppm (0.2%) 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 only Up to 500 ppm (0.05 %) A higher sulphur content than 15 ppm may only be used where Stage III A/Tier 3 or less restrictive emission laws apply. Engines with both EGR and SCR Up to 350 ppm (0.035%) A higher sulphur content than 15 ppm may only be used where Stage III A/Tier 3 or less restrictive emission laws apply.
A higher sul- phur content than 350 ppm is not permitted, since this will result in engine damage.
