# Service bulletin A171344 2035463\- A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10121302 - Published by NHTSA: 2017\-10\-31 - Manufacturer's number: A171344 2035463\- - Manufacturer's date: 2013\-10\-22 - NHTSA component: ENGINE AND ENGINE COOLING ## NHTSA's summary 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, and the ambient temperature and road conditions. Additional factors include the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. Utilizing the advanced sensor technology integrated in models equipped with the 3.0 TFSI engine, it is possible to measure oil consumption electronically via a Guided Function test plan. If the electronic oil consumption test is not available for this model, perform the test with the conventional scale/oil weighing method. See TSB 2018550 for instructions for the conventional scale/oil weighing method. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2013/MC-10121302-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2013/MC-10121302-0001.pdf) The document is the manufacturer's.
