What kind of engine oil does the Volkswagen Santana use?

[KateFitz]

Volkswagen Santana uses Volkswagen's original engine oil, with the model number 5w40, which is a synthetic oil. If you want 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 low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. 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 temperatures. The method for changing the engine oil in a Volkswagen Santana is as follows: Wait for the engine temperature to drop, and also allow 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 some oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover's oil filler port. Generally, pour about three-quarters of a bottle of oil; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the dipstick and check that the engine oil level is within the standard range.
