SDI (engine)
The SDI engine is a design of
applications.The SDI brand name (derived from "Suction Diesel Injection" or "Suction Diesel Direct Injection", the latter a literal translation of the German: Saugdiesel-Direkteinspritzung)[4][5][6] was adopted in order to differentiate between earlier and less efficient indirect injection engines, called SD[4] or "Suction Diesel", which were also produced by Volkswagen Group.
SDI engines are only produced in
The SDI engine is generally utilised in applications where

Lubricants
Like their related Volkswagen Group
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".[citation needed] Only Volkswagen AG can grant the necessary approvals, following in-house testing.[citation needed] 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.[17]
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.[14] According to VW 'generic' longlife lubricants, or those certified by other manufacturers such as General Motors,[18] BMW[19] or Mercedes-Benz[20] should not be used.
