What kind of oil should be used for MG 6 maintenance?
3 Answers
MG 6 uses 5W-40 semi-synthetic oil. Definition of semi-synthetic oil: Semi-synthetic oil is a type of motor oil that uses semi-synthetic base oil. Cars using semi-synthetic oil generally require an oil change every 7,500 kilometers, while conventional oil usually needs to be changed every three months. Oil change and selection: The oil change should be determined based on the actual driving environment and driving habits. In harsh driving conditions, the oil should be changed earlier. The oil change is not a fixed time, and car owners should make reasonable choices. The type of motor oil should also refer to the recommendations in the car maintenance manual.
I've been driving this MG6 for several years and always use 5W-30 full synthetic oil for maintenance, as specifically recommended in the owner's manual. To be honest, the OEM oil recommended by the 4S shop is sufficient, but if you're buying it yourself, major brands like Mobil, Shell, or Castrol are all good options. Just make sure to choose SP or SN grade oil - protecting the turbocharged engine is particularly important. I mostly drive in the city and change the oil every 8,000 kilometers. If you frequently drive on highways, you can extend the interval slightly. Don't forget to replace the oil filter when changing the oil, and never use off-brand oil as it can damage the engine. Once I used cheap oil and clearly felt the acceleration was sluggish, so I switched back to full synthetic oil obediently afterwards.
My car-modding buddy told me the MG6's 15C4E engine is quite sensitive to oil, so special attention should be paid to the HTHS (High Temperature High Shear) viscosity parameter. He recommends using top-tier full synthetic oils like Mobil EP or Shell Helix Ultra that meet ACEA C5 standards—either 0W-20 or 5W-30—to better protect the turbocharger. In northern winters, 0W ensures quicker cold starts, while 5W suffices in the south. Oil change intervals depend on driving conditions: frequent stop-and-go traffic calls for more frequent changes, and I personally change mine every 5,000 km due to off-road job sites. Also, remember to check the air filter before maintenance—excessive dust intake can affect engine performance.
