What kind of engine oil is used for the Tiguan L?
1 Answers
The Tiguan L uses 5W40 engine oil or 0W40 fully synthetic engine oil. If you want to change the oil during later maintenance, you can choose from three different types of oil: 5W-30 Castrol fully synthetic, 5W-40 original fully synthetic, and 5W-40 original mineral oil. 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, with 5W representing the ability to 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 indicates better ability to maintain viscosity at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in the Tiguan L 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 and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a special 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 oil filler cap on the engine valve cover, typically filling about 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, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the oil level is within the standard range.
