How often should the MG 6 fuel filter be replaced?
4 Answers
The fuel filter of the MG 6 generally needs to be replaced every 20,000 kilometers. The fuel filter is mainly installed in the fuel pipe next to the fuel tank and serves to filter impurities in the gasoline. The replacement cycle of the fuel filter should also be determined based on the usage of the car. If the car is properly maintained, the replacement cycle of the fuel filter can be appropriately extended. Here are some related details: 1. The fuel filter must be replaced when the engine is cold, as the high-temperature exhaust gas discharged from the exhaust pipe when the engine is hot can also ignite the fuel. 2. If the filter is severely clogged, it will increase the intake resistance and reduce the engine power. At the same time, due to the increased air resistance, it will also increase the amount of gasoline drawn in, leading to an overly rich mixture ratio, which will deteriorate the engine's operating condition, increase fuel consumption, and easily cause carbon deposits. It is recommended to develop the habit of regularly checking the air filter element. Depending on the specific driving environment, it is suggested to replace the air filter every 10,000-15,000 kilometers.
I've been driving my MG6 for three years now, and the fuel filter replacement really depends on the manual and actual driving conditions. The manufacturer generally recommends changing it around 30,000 kilometers, but if you frequently refuel at small gas stations, you might need to check it at around 20,000 kilometers. A while ago, my car was experiencing acceleration hesitation, and the repair shop found the filter was clogged—when they took it out, it was full of black impurities. This part is like putting a mask on your engine; when it's dirty, it not only increases fuel consumption but can also cause excessive wear on the fuel pump in severe cases. Replacing it yourself is quite challenging, as you need to remove the rear seat and access the fuel tank, so it's best to have a mechanic check it during regular maintenance rather than waiting for the warning light to come on. For city commuting, you can extend the interval slightly, but don’t exceed 40,000 kilometers.
Having worked on cars for ten years, I've handled quite a few MG6 gasoline filters. The filter is located inside the fuel tank and integrated with the fuel pump, with a designed lifespan of about 40,000 km. However, actual performance depends on fuel quality—some owners using 95-octane fuel have run up to 50,000 km before replacement, while those consistently using poor-quality 92-octane needed changes at just 25,000 km, with the filter paper completely clogged. A crucial tip: if you experience hard starting, weak acceleration, or rough idling, don't just check the spark plugs—test the fuel pressure first. Last year, an MG6 broke down because a completely clogged filter caused fuel pump failure, costing an extra 2,000 yuan in repairs. OEM filters cost around 400 yuan—never use aftermarket ones.
Just helped a colleague with an MG6 filter issue. When his car reached 38,000 kilometers, the fuel consumption suddenly increased by 2 liters, and the engine malfunction light flashed. The repair shop's computer detected low fuel pressure, and upon opening the fuel tank, they found half of the filter clogged with gummy deposits. The mechanic mentioned that ethanol-blended gasoline tends to produce gel-like substances and recommended mandatory replacement every 3 years or 30,000 kilometers. Buying the filter online costs a little over 200 yuan, but the labor fee is 300 yuan because the fuel tank needs to be emptied, and the fuel pump wiring harness must be removed. Those with strong DIY skills can attempt it, but be sure to replace the fuel tank cap sealing ring, otherwise gasoline fumes may seep into the cabin.
