The Tharu uses 5W40 engine oil, which has a relatively high viscosity and is suitable for German or American cars. Additionally, if the car is new, you can use engine oil with lower viscosity. For older cars, it's better to use engine oil with higher viscosity to ensure the engine operates more efficiently. The Tharu is a compact SUV under the Volkswagen brand, with dimensions of 4453mm in length, 1841mm in width, and 1632mm in height, and a wheelbase of 2680mm. The Tharu is equipped with two engines: a 1.4-liter turbocharged engine and a 2.0-liter turbocharged engine.

Oh you asked the right person, I've personally maintained my Tharu three times already. Choosing engine oil is really not something to be careless about, especially for turbocharged engines. The 1.4T and 2.0T models actually use different specifications! For my 1.4T China VI model, the dealership directly used 0W-20 low-ash oil with VW50800 certification printed on the barrel. I remember last time my friend tried to save money by using 5W-30, and the particulate filter warning light stayed on for half a month - the cleaning cost over 1,000 yuan. The manual recommends oil changes every 10,000 km, but since I often drive to construction sites, I can feel the engine sound getting rougher by 7,000 km.

Last week, while helping my neighbor check the maintenance sheet for his Tharu, I noticed the wrong engine oil type was used. Remember these two practical tips: First, check the oil filler cap under the hood—it usually has the recommended viscosity engraved. Second, refer to Chapter 12 in the manual. Most Tharus use 5W-40, but newer models with particulate filters require VW508-certified 0W-20 oil, identifiable by the blue label on the bottle. Workshop staff sometimes mix them up, so you need to be extra careful. Using the wrong oil might not show immediate effects, but it can lead to a significant increase in fuel consumption—the most extreme case I've seen was an extra 3 liters per 100 kilometers.

Last time before driving the Touareg to Tibet, I specifically researched the engine oil issue. In high-altitude areas, you need oil with better fluidity; 0W-grade oil won't solidify even at -35°C. At the 4S shop, I saw a notice posted in the workshop: vehicles manufactured after 2019 must use 0W-20 oil meeting the VW50800 standard. The mechanic said cars with GPF using regular oil might clog the filter in just six months. During maintenance, it's advisable to supervise the oil change—I've seen workers mix leftover oil directly, and additives from different brands can conflict.
