| A171232 2018550- | 2017-11-08. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 17 number 12 - 31 dated August 30, 2012. Oil consumption measurement - Repair Authorization (CA). 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. |
| A371267 2028053- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN. Supersedes Technical Service Bulletin Group 37 number 11 ? 31 dated December 1, 2011.
