Does the 2021 CR-V Earth Dream engine still have oil dilution issues?

2021 Honda CR-V models do not experience oil dilution issues. Here are the detailed explanations: 1. Cause: This typically occurs when the engine injects excessive gasoline during startup. Sometimes due to over-injection and incomplete combustion, excessive cylinder wall pressure forces gasoline into the crankcase. Normally, gasoline would evaporate when the engine reaches operating temperature, but frequent cold starts and cold weather can prevent the oil from warming up sufficiently, making it difficult for gasoline to evaporate, thus leading to increasing oil levels. 2. Company actions: Dongfeng Honda announced a recall plan, deciding to recall 130,455 CR-V vehicles equipped with 1.5T engines produced between February 14, 2017 and February 27, 2018 starting from May 22, 2018. The recall measures include: reprogramming the ECT and TCU to primarily increase fuel injection pressure and reduce fuel injection quantity.

I previously drove a 2021 CR-V Earth Dreams as my daily commuter for almost a year without encountering oil dilution issues. Honda made extensive optimizations to the engine system after 2019, including upgrading ECU software and adjusting fuel injection, which significantly reduced the likelihood of gasoline diluting the engine oil. I checked the oil dipstick every two weeks, and the level remained consistently stable. I recommend owners avoid frequent short-distance driving, especially in winter, and allow the engine to warm up for a few minutes after cold starts. Overall, the 2021 model has been refined to a mature state with notably lower failure rates—maintain it properly, and you can use it with peace of mind.

I think the 2021 CR-V Earth Dreams has made significant progress in oil management, and Honda's recall actions have indeed worked. After the engine design adjustments, the issue of gasoline mixing with engine oil has basically disappeared. I drive this car myself, and whether it's long-distance or city driving, there are no abnormalities. Regular maintenance is key – changing the oil every 5,000 kilometers and choosing the right viscosity synthetic oil. If you occasionally notice slightly high oil levels, it might be due to measurement errors or environmental factors, so don't panic too much; in most cases, it's normal. Honda has also enhanced sensor monitoring to ensure the engine runs healthily.

Drove my friend's new CR-V, the Earth Dreams engine runs smoothly with stable oil condition. Honda has fixed the flaws of the older models, and the 2021 version optimized the fuel system, reducing gasoline contamination caused by cold starts. During daily driving, checking the oil dipstick is straightforward—just ensure it's at the normal position. Use it with confidence, the issues have been resolved.

I'm quite confident about the oil condition in my 2021 CR-V Earth Dreams. Honda has addressed the fuel dilution risk through software updates. In my actual usage, I haven't encountered oil level increase, but I recommend developing good habits: check the oil dipstick monthly and avoid frequent hard acceleration. For engine maintenance, using high-quality oil can further prevent issues. If there are rare reports of residual faults, they're mostly due to maintenance negligence or lingering effects from older models. Overall, the new model has high reliability.

Observing the new CR-V Earth Dreams, oil dilution has become rare in the 2021 model. Honda's improvement plan includes enhanced fuel filtration and engine sealing, effectively preventing oil contamination. When driving, I pay attention to the driving mode to minimize the impact of short-distance trips. Regular checks and maintaining standard oil levels are essential to avoid overfilling or underfilling. With this engine optimization, the failure rate has dropped significantly, making safe driving more worry-free.
