Problem overview

Some Chrysler 300 owners report experiencing excessive oil consumption, with some vehicles using a quart of oil every 800 to 2000 miles without any visible leaks or smoke. This issue may be linked to a sticky PCV valve, which can cause increased oil consumption, or potentially due to manufacturing defects in engine components. To address these concerns, some owners have found it necessary to replace the PCV valve. Additionally, it is suggested that owners check the crankcase ventilation system to prevent oil buildup in the throttle body or intake manifold. Using oils formulated for specific environmental conditions may also help mitigate these issues. Regular maintenance and monitoring of oil levels are recommended for those facing excessive oil consumption in their Chrysler 300.
