What kind of oil should be used for Volkswagen Tharu?
1 Answers
Volkswagen Tharu uses 5w-40 or 0w40 fully synthetic original engine oil. For later maintenance and oil changes, you can choose from brands such as Mobil, Shell, and Castrol. Any 40-viscosity oil that meets Volkswagen's 502 certification can be used. For Volkswagen Tharu 1.4T and 2.0T models, 5w-40 fully synthetic oil is recommended. 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—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 oil's kinematic viscosity at 100°C. A higher number 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 oil in a Tharu 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 underneath to catch the old oil until it stops flowing. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover filler port, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the oil level is within the standard range.
