Which brand of engine oil is the best?

I think it's stronger than Castrol Extreme Power Protection, you can try it first, and you can change to another brand later. I am the imported GT Magic Red engine oil that I changed later, and the friend sent it can not be wasted, to tell the truth, Mobil Gold is really a little worse than the pure imported GT Magic Red, GT's mute performance is better, and another is long-lasting, I now have no attenuation for more than 10,000 kilometers.

What suits you is the best, you can choose the original car with engine oil, you can also choose Shell, Castrol, Mobil, are also big brands, but you have to buy it in a regular store, as long as it is real oil, buy the right model.

If you are not really a "friend", then you should choose a 4S store or a cost-effective one recommended by the original factory!

There is no need to pursue the so-called *** good reputation! (Because the engine oil on the market is mixed, it is difficult to distinguish between whites, there is no formal channel, and the quality is difficult to guarantee.) )

Three guarantees to use the original engine oil on it, the warranty period of the maintenance content are specified by the manufacturer, in addition to the first warranty to replace the oil filter are at the customer's own expense, if the original engine oil can not guarantee the requirements of the engine work, the manufacturer will not provide this specification of oil, because during the warranty period if the vehicle quality problems cost is borne by the manufacturer, and the cost of maintenance is at the customer's own expense, which manufacturer will not do to let the customer save costs and take the risk of their own things.

Which brand of engine oil is better? The best YACCO brand oil is the one that suits your car.

At present, the engine oil on the market can be simply divided into mineral oil and synthetic oil due to its different base oils, and synthetic oil can be divided into semi-synthetic and fully synthetic. The engine oil is generally made of base oil + additives, the quality of the base oil is very important for the performance of the engine oil, it provides the most basic performance of the engine oil, good foundation (high-quality base oil) + good auxiliary (additives) = good engine oil.

Mineral oil is a base oil made from the residual bottom oil after the useful hydrocarbon substances are fractionated during the refining process. In essence, the use of the worst in the composition of the poor, in the refining process due to the inability to remove the impurities contained, the strength of the base oil is weak, the performance is unstable, the flow point is high, not suitable for operation in low temperature areas, the quality is limited, the first is cheap, the lubrication performance and service life are inferior to the synthetic oil, the need for a larger viscosity relative to the synthetic oil to meet the lubrication needs of high load, the environment has greater pollution. Recommended Oil Change Interval:

5000 km.

Semi-synthetic. The engine oil prepared from the international three types of base oil is the product purified by hydrogen fission technology on the basis of mineral oil, which is mixed by mineral oil and synthetic oil in a 4:6 relationship, the purity is close to that of fully synthetic oil, and the cost is slightly higher than that of mineral oil.

Recommended oil change interval: 7500 km.

Fully synthetic. It is a high-grade oil in motor oil. Ethylene and propylene dispersed from gas or natural gas imitation from the first grade, and then refined into a base oil composed of macromolecular bypass through complex chemical reactions such as polymerization and catalysis, in essence, the use of better components in the first grade, chemical reaction and artificial control to achieve the expected molecular form, the molecules are neatly arranged, and the ability to resist external variables is naturally strong, so the quality is better, and the properties such as thermal stability, oxidation resistance, and viscosity change resistance are much stronger than mineral oil.

Stability and anti-aging ability is incomparable to mineral oil, especially for models with engine supercharging technology, when the supercharged parts start to work, the engine torque will increase exponentially, at this time, the oil film covering the engine crankshaft will withstand several times higher shear force than before, only high-quality fully synthetic oil can fully meet the needs of the oil film; Although semi-synthetic oil has good performance, in terms of anti-aging ability and oil change interval, fully synthetic is better than semi-synthetic. Recommended oil change interval: 10000 km.

Personally, I recommend that you choose Mobil One fully synthetic engine oil, which can be maintained once a year or 10,000 kilometers.

Everyone's car is different, so it is necessary to judge what kind of engine oil to use according to the situation of the car.

Viscosity: Generally, the Japanese and Korean automobile engines have good airtightness, and the viscosity will be slightly lower, and the general ones are the majority, and the German and American cars generally have a higher viscosity, more than 40;

Low temperature mobility: depending on the region, generally in northern China such as Heilongjiang, Liaoning and other regions in winter above minus 40 degrees, it is recommended to use 0w, and the minimum temperature in other regions is not less than minus 35 degrees, 5w is enough;

Grade: engine oil is divided into mineral oil, semi-synthetic, fully synthetic, the quality grade of fully synthetic engine oil is the highest, generally with turbocharged cars are recommended to use fully synthetic engine oil, fully synthetic engine oil is the best protection for the car, but not all cars are recommended to be fully synthetic, some semi-synthetic or mineral oil is enough;

In addition, some car owners will use a slightly higher viscosity of the oil in summer, in fact, many engine oils are common in all seasons, not necessarily in the summer to change the viscosity of the oil, must jump out of this circle.

Hope it helps.

If you are maintaining it in a 4S shop, you can use the original engine oil.

If you are doing your own maintenance outside, it is recommended that you use Castrol or Shell oil.
