Generally speaking, domestic manufacturers of naturally aspirated Great Wall Car engine models will require users to replace the lubricant when driving 5,000 kilometers to 15,000 kilometers, while supercharged Great Wall Car engine models require replacement when driving 5,000 kilometers. If the car is not driven much or has been in a state of suspension, it is best to replace the engine oil every six months. Of course, if the environment and oil quality you are in are good, you can appropriately extend the oil change cycle and time.
The function of the oil filter is to filter impurities, so it should be replaced together with the oil. If it is not replaced, the oil cannot be filtered, which will cause the internal parts of the Great Wall Car engine to wear faster due to impurities in the oil.
3. Irregularly replace the air filter
If the filter is severely blocked, the intake resistance will increase and the power of the Great Wall Car engine will decrease. At the same time, due to the increase in air resistance, the amount of Petrol Car inhaled will also increase, resulting in an excessively rich mixture ratio, which will deteriorate the operating state of the Great Wall Car engine, increase fuel consumption, and easily produce carbon deposits. You should develop the habit of checking the air filter element regularly.
4. Irregularly replace the brake fluid
One characteristic of brake fluid is that it absorbs moisture from the air, and the brake hydraulic system must allow the brake fluid to communicate with the atmosphere to operate normally. Over time, the brake fluid will absorb moisture and turn into bubbles at high temperatures. When bubbles appear in the brake oil circuit, the braking efficiency will decrease. Therefore, the brake fluid should be checked in time for its quality and performance and replaced on time according to the climate, operating environment, seasonal changes and working conditions. Replace it every two years or when driving 50,000 kilometers. When choosing and replacing brake fluid, remember: do not mix brake fluids of different types and brands. Due to different formulas, mixed brake fluids will cause the brake fluid index to decrease.
5. Irregularly replace antifreeze
If the antifreeze is not replaced for a long time, the anti-corrosion, anti-rust and anti-scaling functions will be reduced, which will cause cooling system failures and even rust. Generally speaking, antifreeze is generally replaced every 1.5 to 2 years.
