What kind of engine oil is suitable for the Tiguan L?
2 Answers
The original engine oil brands for the Tiguan L are Premium Select Genuine Oil and Mobil 1 ESP, with specifications of 5W-30 and 5W-40. If you want to change the engine oil during later maintenance, you can choose brands such as Shell and Castrol. 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 low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it can maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil of the Tiguan L 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 out; Use a special wrench to remove the oil filter; apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover. Generally, fill up to three-quarters of the oil container; 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, 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.
I've been driving the Tiguan L to work every day, and I feel that choosing the right engine oil is crucial. I used to use regular oil, but after switching to a full synthetic 5W-40, the engine immediately became quieter and the acceleration smoother. The manual recommends Volkswagen's VW 502 standard oil, with regular changes every 10,000 kilometers. Don't just buy cheap oil—if the specifications are wrong, fuel consumption can skyrocket or the engine may wear out prematurely. In winter, synthetic oil flows better during cold starts, preventing the engine from stiffening. Actually, buying oil from a reputable shop is sufficient. I regularly check the oil dipstick to ensure it's not cloudy. In short, just like people, cars need the right 'food' to stay healthy.
