When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the power stroke, part of this oil layer is consumed in the combustion process. Varying rates of oil consumption are accepted as normal in all engines. The accepted rate of oil consumption for engines used in the vehicles listed above is 1 quart (0.946 liter) in 2,000 miles (3,200 km) for the 1st 50,000 miles (80,467 km). For vehicles with more then 50,000 miles (80,467 km) the acceptable oil consumption for engines is 1 quart (0.946 liter) in 750 miles (1,207 km). There are many factors that can affect a Owner's concern with oil consumption. Driving habits and vehicle maintenance vary from owner to owner. Inspect each condition listed below prior to determining if the vehicle in question has abnormal engine oil consumption. If abnormal oil consumption is suspected, refer to the detailed diagnostic procedures available in DealerCONNECT> TechCONNECT under: Service Info> 09 - Engine> Diagnosis and Testing - Oil Consumption Test And Diagnosis.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10149704-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10149704-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10149704","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FCA","model":"ALL MODELS","year_from":2012,"year_to":2015,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
