:Notes:
Volkswagen Marine engines were originally rated according to
Directive 80/1269/ EEC. However, some are now being rated to
ISO 8178-4. ==Lubricants== Like their related Volkswagen Group
Turbocharged Direct Injection diesel engines, Volkswagen AG requires that motor oil lubricants for SDI engines must conform to one of the officially approved standards VW505.00, 505.01, 506.00, 506.01, or 507.00. 'Generic' oil standards such as the
American Petroleum Institute 'API', or
European Automobile Manufacturers Association 'ACEA' are not in themselves recognised or approved by VW, although such an oil may also conform to one of the specific VW standards. Many formulations of motor oils from most brands are now "VW Approved" to the above standards. However some unapproved 'off brands' print the VW number on the label, implying that they meet the said standard, but hide in small type the word "recommended". Only Volkswagen AG can grant the necessary approvals, following in-house testing. Volkswagen Germany (and Volkswagen of America) publish up-to-date lists of currently approved oils on their respective websites, along with the technical resource, erWin. All SDI-engined models with "LongLife Servicing", "Extended Service Intervals", "ESI", or "WIV", must be lubricated by official 'LongLife' lubricants, namely VW506.00 (for non-PD), VW506.01 (for PD), or VW507.00.
BMW or
Mercedes-Benz should not be used. ==SDI vs other VW Group diesel engines== The following table contains a selection of current and historical

diesel engines for comparison of performance and operating characteristics with other naturally aspirated and forced induction engines of the same capacity: == References ==
