What kind of engine oil should be used for Haval H2?
3 Answers
The original factory of Great Wall Haval H2 uses SL grade 10W-40 semi-synthetic engine oil, and any engine oil of the same specification can be used. In addition to the original factory oil, you can also choose engine oil brands such as Shell, Mobil, and Castrol. If SAE-10W-30 or higher viscosity engine oil is used in cold weather, the engine may be difficult to start. Therefore, SAE-0W-20, 5W-20, or 5W-30 engine oil is recommended for northern regions. Using 0W-20 engine oil can maximize fuel savings. More information about engine oil is as follows: 1. Function of engine oil: Engine oil refers to the lubricating oil specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. 2. Hazards of overfilling: If too much engine oil is added, it will increase the amount of oil splashed into the cylinder wall when the crankshaft and connecting rod rotate, increase the rotational resistance of the crankshaft, reduce the engine's output power, and increase fuel consumption. 3. Appropriate filling amount: It is advisable to keep it slightly below the MAX mark on the oil dipstick. The engine oil dipstick has an upper limit and a lower limit, and the oil level should be between the upper and lower limits.
As an owner of a Haval H2, I always follow the recommendations in the user manual when selecting engine oil. The manual recommends using 5W-30 viscosity oil because it performs well in both cold and hot weather, ensuring smooth engine starts and stable operation. I usually use fully synthetic oil brands like Shell or Castrol, changing it every 7,500 kilometers or every six months. Timely oil changes not only reduce engine wear but also prevent increased fuel consumption or noise issues. Don’t skimp by buying off-brand oil, as it could lead to malfunctions and compromise driving safety. Simply put, sticking to the manual is the easiest way to keep your car running well and extend its lifespan.
DIY car repair is my hobby. When changing the oil for my Haval H2, I always use 5W-30 full synthetic oil that meets the API SN standard. Choosing reputable brands like Mobil ensures lubrication effectiveness and prevents engine damage. The procedure includes warming up the engine for a few minutes, loosening the oil pan bolt to drain the old oil, and adding about 4 liters of new oil while paying attention to safety precautions. Using the wrong viscosity, such as 10W-40, can increase friction, leading to higher fuel consumption or reduced power. Regular oil changes every 5,000 kilometers help clean carbon deposits and maintain engine efficiency. DIY is fun, but quality is key—don't skimp on costs by buying counterfeit products to ensure driving reliability.
