What kind of engine oil is best used by Volkswagen Lavida to improve the problem of high speed weakn

You should still use the original engine oil, semi-synthetic, the quality is not very good, there is no problem with running the city normally, but the engine temperature and pressure at high speed are much higher than normal, and you are still a Volkswagen EA211 engine, the quality of the oil is higher, the semi-synthetic can not meet the requirements, thinning, the power is naturally poor, mine is with the original factory ran a trip to high speed, uncomfortable to death, when the maintenance is directly replaced with German GT oil, high quality, On New Year's Day, I went back to my hometown, the high-speed power is very full, as long as the oil speed is raised, there is no feeling of meat after the speed starts in winter, and the start in the morning is much smoother than before.

How big is your displacement car, how old is it? Has there been a major accident, and is it being maintained on time and per kilometer? What type of engine oil is recommended for the original car?

Many of the original engine oil of the public are Castrol labeled, such as maintenance in the 4S store, there will generally be no problem, if you change it yourself, be sure not to add miscellaneous brands, and the engine with T is more recognized as the oil.

If the viscosity of the oil is low, it will be much better to replace it with a slightly higher viscosity, if the viscosity is not a problem, the oil is too poor, and you need to change to a higher quality oil, I am now using GT engine oil, PAO base oil, the quality and performance are very good, I have used it for almost a year, the power is very strong at high speed, and there has been no engine weakness.

This may be a leak, which is what we call coolant.

The problem of engine noise is large, the engine noise should have a lot to do with the lubricating oil used, mainly check the use of Dakai engine oil, it is recommended that you first quietly change the viscosity of the oil to try. In addition, if you add gasoline with a better quality than the imitation circle, it may cause the engine power to decrease, and it will cause more carbon deposits inside the engine, which will also cause the engine noise to increase;

Volkswagen Lavida can use Volkswagen's special 5W40 engine oil, and 4L engine oil is usually added for 5000 kilometers of maintenance. For Lavida's self-priming engine, it is best to use 5w40 engine oil as well. Compared with 5w30 and 5w40, 5w40 has the same low-temperature fluidity, but different high-temperature properties.

5w40 has better high temperature protection and sealing performance. According to the structure and operating state of Lavida self-priming engine, better cooling and lubrication of the internal components of the engine with higher viscosity are required.

Lavida has a self-aspirated engine and a turbocharged engine. Due to the different engine structures, the oil requirements for these two engines are also different.

Naturally aspirated engines have average oil quality requirements, mineral oil and semi-synthetic oil can be used, and fully synthetic oil can be used for large budgets. Compared with the self-priming engine, the internal parts of the turbocharged engine are more precise, the working conditions are more complex, the oil performance requirements are higher, the oil flow is better, and it is best to use fully synthetic engine oil.

The extremely stable molecular structure of synthetic engine oil makes the oil have super oxidation stability and extraordinary wear resistance, effectively prolonging the service life of the engine. Most of the products on the market labeled with synthetic oil have a PAO content of less than 12%. In synthetic engine oils, 100% PAO (poly-olefin poly; - olefins) are prepared from base oils and additives.

Road tests in the laboratory have shown that synthetic motor oils achieve the ideal combination of viscosity, lubricity, volatility and cleanliness to maximize engine protection and minimize friction and fuel consumption. This is because too much lubricating oil can enter the combustion chamber through the gap between the cylinder and the piston, and carbon deposits are formed by combustion. If it falls into the cylinder, it will aggravate the wear of the cylinder and piston, and accelerate the contamination of the lubricating oil.

For the choice of lubricant brand, which requires long-term use of lubricant, Mobil lubricants can be used. Pay attention to the cleanliness of the oil, you can use Shell oil; If you need a lubricant with strong film toughness, you can choose Castrol. For example, turbocharged engines are prone to carbon build-up at high speeds, so you can use Shell synthetic engine oil, which has a strong cleaning ability.
