When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines. The purpose of this bulletin is to describe different instances where oil consumption occurs and to make available a worksheet to assist the technician in determining if oil consumption is excessive.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10225520-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10225520-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10225520","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ISUZU","model":"N-SERIES","year_from":2012,"year_to":2023,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
