What are the common issues with the Dongfeng MX6 engine?
2 Answers
The common issue with the Dongfeng MX6 engine is that abnormal noises may occur after a period of use. Below is additional information: The engine used in the Dongfeng Fengdu MX6 is the MR20 engine. The MR20 engine is a straight-four engine jointly developed by Nissan and Renault. It features an all-aluminum construction, double overhead camshafts, a 16-valve configuration, and is equipped with a CVTC continuous variable valve timing control system. The MR20 engine is known for its stability, affordable maintenance, slightly higher fuel consumption compared to direct injection engines, and its mature yet somewhat outdated technology. Engine maintenance tips: Use lubricating oil of appropriate quality grade; Regularly change the oil and oil filter; Maintain good crankcase ventilation; Regularly clean the crankcase; Periodically clean the fuel system; Regularly maintain the radiator.
Last time I drove my Dongfeng MX6 for a long period, I noticed something wrong with the engine - it burns oil excessively, requiring top-ups every few thousand kilometers like it's drinking oil. There's also this distinct tapping noise, especially noticeable during cold starts. After inspection, it was identified as a design issue with the chain tensioner requiring regular adjustments. Carbon buildup is another persistent problem causing sluggish throttle response and soaring fuel consumption. Since I drive frequently, I pay extra attention to maintenance - cleaning the intake ports every six months to prevent minor issues from escalating. The engine shares some similarities with the old Qashqai's platform - durable but demands consistent upkeep. I recommend using full synthetic oil to prolong its lifespan. In summary, these are common issues but manageable if addressed promptly - don't wait until it becomes a costly repair.
