Supersedes Technical Service Bulletin Group 10 number 12-05 dated March 20, 2012. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner?s Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. Under certain driving conditions, internal engine pressure conditions in the 2.0 TFSI engine can negatively influence the rate of oil consumption. This condition can occur while the vehicle is operated in metro driving conditions; for example: stop-and-go traffic with extended idle periods.
