Has the CRV engine oil dilution issue been resolved?
2 Answers
CRV engine oil dilution has been resolved. Here is the relevant introduction of CRV: 1. Drive system: Honda CRV offers two models, one is a two-wheel drive version and the other is a four-wheel drive version. The four-wheel drive version uses a front-mounted four-wheel drive system with an on-demand four-wheel drive configuration. 2. Powertrain: Honda CRV is equipped with two i-VTEC engines, a 2.0L and a 2.4L. The 2.0L engine has a maximum power output of 114kW and a maximum torque of 190N·m, while the 2.4L engine delivers a maximum power of 140kW and a maximum torque of 222N·m. 3. VTEC technology: Honda CRV features VTEC engine technology, which stands for Variable Valve Timing and Lift Electronic Control System. Unlike conventional engines, VTEC engines differ in the number of cams and rocker arms as well as the control method. They have two different sets of cam profiles for low-to-medium speed and high-speed operation, allowing automatic switching through electronic control system regulation. With the VTEC system, the engine can automatically adjust valve opening timing and lift according to driving conditions, thereby altering intake and exhaust volumes to achieve increased power, reduced fuel consumption, and lower emissions.
The CRV oil dilution issue primarily affected certain models from 2017 to 2019, caused by gasoline mixing into engine oil leading to elevated oil levels. Honda later issued a recall, implementing ECU system software updates to optimize fuel injection and engine warm-up processes, effectively reducing oil dilution. I've seen many owners report the problem virtually disappeared post-recall, with normal oil inspection results. However, driving habits matter too: avoiding frequent short cold starts and ensuring proper engine warm-up during long drives can prevent fuel residue issues. For newer CRV models, Honda improved engine design - virtually no similar complaints have been reported since 2020. Owners of affected vehicles should confirm recall status with authorized dealers for free rectification.
