    Sulphur in diesel was dropped to under 10 ppm (parts per million) as of a few years ago because of exhaust aftertreatment systems. The sulphur becomes soot and after a regeneration is left as ash. Ash will eventually block the DPF (diesel particulate filter) meaning it will need to be cleaned by the dealer or in some cases replaced depending on the system. Sulphur also affects DOCs (diesel oxidation catalyst) used with ad blue (urea) after treatment systems, sulphur was used for lubrication in fuel. if you always use a known brand fuel which as pointed by SB can come from any refinery you should be fine.
    Common rail fuel filters normally filter as low as 2 microns (a micron is a millionth of a metre) so that’s pretty small, never pre fill the fuel filter as you will put unfiltered fuel in the system always prim it through. If you install an extra fuel filter do it before the OEM filter and use a 10 to 15 micron water separator style filter.
    Also check the engine oil you use if you have a DPF as the high detergent oils also block the DPFs, special spec oil is required.

    Yeah, The Cruze`s DPF has a cleaning light that comes on on the dash, flashing like a madman :laugh: The process is to keep driving, drop it back a gear and keep the revs over 200rpm for between 8 to 12 minutes or till the light goes out . This apparently enables it to burn off the soot (hence all the smoking we had) :laugh:

    If it can`t clean it, a service light then comes up & the dealer has to clean or changeot the filter :whistle:
