What brand of engine oil is best and how many kilometers should I change it?

Generally, semi-synthetic engine oil is changed once every 5000 kilometers, and fully synthetic engine oil is changed once every 7000 kilometers or 8000 kilometers. Of course, there are also long-lasting, imported GT Magic Red, and the 10,000 kilometers of this kind of PAO can also be used. The main thing is to consider your own needs, the cost performance is about the same, and it is more cost-effective to change the long-lasting engine oil if you usually run more.

Engine oil is divided into mineral engine oil and synthetic engine oil, and synthetic engine oil is divided into fully synthetic and semi-synthetic, and fully synthetic engine oil is the highest grade. When changing the engine oil, refer to the vehicle's owner's manual and change it according to the recommended specifications. Note that the filter is performed at the time of the oil change.

Mineral engine oil is changed every 5000 km or every 6 months;

Synthetic engine oil 8000-10000 km or change every 8 months.

Transmission fluid. Transmission oil plays a role in lubricating and extending the life of the transmission, and transmission oil is divided into automatic transmission oil and manual transmission oil.

Manual transmission oil is generally replaced every 2 years or 60,000 kilometers;

Automatic transmission fluid is generally changed every 60,000-120,000 km.

Booster oil. Booster oil is a kind of liquid in the power steering pump of automobiles, which can make the steering wheel lighter through hydraulic action, which was used in large cars in the early days, and now basically every car has this technology.

The booster oil is generally replaced every 2 years or 40,000 kilometers, and it should be regularly tested for lack and replenished.

Brake fluid. Due to the structure of the automobile brake system, the brake fluid will absorb water over time, resulting in a decrease in braking force or brake failure.

Brake fluid is generally replaced every 2 years or 40,000 km.

Antifreeze. After a long time, something will deteriorate, and the same is true for antifreeze, which is normally replaced every two years or 40,000 kilometers. Regularly check the level of antifreeze and make up to the normal range.

Mobil can. Mobil's parent company, Texas-based ExxonMobil, is the world's largest privately owned oil and gas producer and refiner, and has now surpassed Apple to become the world's most valuable company. In China, with the continuous increase in car ownership, the demand for motor oil is also increasing, for the Chinese market, Mobil built two ** blending plants in Taicang, Jiangsu Province and Tianjin to provide base oil for Mobil, and the manufacturing of additives is mostly completed in Shanghai.

The Mobil 1 range is a premium range of Mobil oils, which includes Mobil 0W-40, a premium oil with a golden barrel, and 5W W-50 with a grey barrel. Mobil 1 oil is formulated with multiple anti-wear proprietary technologies, coupled with the configuration of its fully synthetic base oil, which makes Mobil 1 very stable when used, according to the published parameters, the service life of Mobil 1 oil can reach 10,000 kilometers (within 12 months).

Fully synthetic oil is generally replaced once after 10,000 kilometers, semi-synthetic oil is generally replaced once after driving about 7,500-8,000 kilometers, and mineral oil is generally replaced every 5,000 kilometers.

At present, there are three types of engine oil used in automobiles, namely fully synthetic oil, semi-synthetic oil and mineral oil, and the service life of these three types of engine oil is different. In addition to the mileage traveled, it is also possible to decide whether to change the oil or not depending on the condition of the oil. The new engine oil has a certain viscosity and will play a good role in lubricating the parts of the car.

Old engine oil, or oil that does not meet the standards for use, looks like water, and such oil will cause a certain degree of wear and tear on the engine and need to be replaced as soon as possible.

Oil characteristics

The parts of the diesel engine are larger and heavier, so the anti-wear ability of the engine oil puts forward higher requirements, while the truck is full of load and runs long distances, mostly for long-term continuous operation, long-term high temperature and high load operation conditions, so the diesel engine oil puts forward higher anti-oxidation requirements, the type of engine oil is different, and the stability is different.

The mineral oil base is obtained from the first refining, that is, after the first oil and gas, gasoline, diesel, kerosene, and heavy oil are proposed, the mineral oil base is then refined, and the last bottom is asphalt. The mineral oil-based color is transparent with a light amber tint, just like the color of salad oil. This oil is characterized by its low cost, and although mineral oil is now only added with various imports, the service life is still about six months.

Mileage: 5,000 kilometers of ordinary oil (4,000 kilometers per day in traffic jams, sandstorms or hot and cold areas).

7,500 km of semi-synthetic oil (6,000 km per day in traffic jams or sandstorms or in hot or cold areas).

The total amount of synthetic silver oil is 10,000 kilometers (8,000 kilometers per day in traffic jams or dust storms or high and low temperature areas).
