What Type of Engine Oil is Suitable for Volkswagen Santana?

[LaAlaina]

Volkswagen Santana uses Volkswagen's original engine oil, with the oil model being 5w40, which is synthetic oil. If you wish to change the oil during later maintenance, you can choose international brands such as Shell, Mobil, or Castrol, or domestic brands like Great Wall, Tongyi, or Kunlun. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, where 5W represents the ability to withstand -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Volkswagen Santana is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the filler cap on the engine's valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check if the engine oil level is within the standard range.
