How Many Liters of Engine Oil Should Be Added for a Haval M6 Oil Change?
2 Answers
Haval M6 requires 4 liters of engine oil for an oil change. The original factory oil for Haval M6 is 5W40 mineral oil. If you wish to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The official Haval M6 manual recommends an oil specification of 5W-30. Any oil model that meets this specification can be used. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Haval M6 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to collect the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a 4-liter oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
As an enthusiast who frequently works in the garage, I've handled quite a few Haval M6 cars. The oil capacity is usually around 4 liters, depending on the specific engine model. For example, the 1.5T version follows this standard value. Don't underestimate this amount—overfilling can cause oil foaming and leaks, while underfilling leads to insufficient lubrication and faster engine wear. I recommend using fully synthetic 5W-30 oil, as it better protects engine performance under both high and low temperatures. The replacement process should be done when the engine is cold. After draining the old oil, slowly add the new oil, checking the dipstick at intervals to ensure the level is between the middle marks. Remember to replace the oil filter at the same time; otherwise, the old filter will contaminate the new oil. Generally, change the oil every 7,500–10,000 kilometers, but if you frequently drive on mountain roads or in heavy traffic, shortening the interval to 5,000 kilometers ensures better maintenance. In practice, if unsure, refer to the owner’s manual or consult a specialized repair shop to avoid guesswork and potential issues. Regular maintenance improves fuel efficiency and makes the car run quieter and more reliably.
