Some 2023 Honda Ridgeline owners report oil consumption that may be related to the Variable Cylinder Management (VCM) system. Understanding VCM helps monitor and manage this concern.
What is VCM?
Variable Cylinder Management deactivates cylinders during light load to improve fuel economy. The system switches between 3, 4, and 6 cylinder operation based on driving demands.
VCM and Oil Consumption
Deactivated Cylinder Conditions
When cylinders are deactivated, they still move but don't fire. Some owners believe this creates conditions that increase oil consumption.
Oil Ring Loading
Deactivated cylinders may not maintain optimal oil ring loading, potentially allowing more oil past rings during these phases.
Normal Consumption Ranges
Honda considers some oil consumption normal. Understanding acceptable versus excessive consumption helps evaluate your specific vehicle.
Monitoring and Management
Regular oil level checks establish consumption patterns. Some owners use devices to disable VCM, though this affects warranty and fuel economy.
