What type of engine oil is used in the Audi Q3?
2 Answers
Audi Q3 uses fully synthetic SM-grade 5W-40 engine oil. The 1.4T model requires 4 liters, while the 2.0T model requires 5 liters. The Audi Q3 uses Audi's official genuine engine oil. If you want to change the oil during later maintenance, you can choose Mobil 1 5W-40 fully synthetic oil, Castrol EDGE 5W-40 fully synthetic oil, or Shell Helix Ultra 5W-40 fully synthetic 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. 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 temperatures. The method for changing the engine oil in an Audi Q3 is as follows: Wait for the engine temperature to cool down, 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 special wrench to remove the oil filter; Apply some oil to the seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the dipstick to check if the oil level is within the standard range.
I've been driving an Audi Q3 for several years, and its engine typically requires 5W-30 full synthetic oil that meets the VW 502 00 or VW 504 00 standards. This is because German car engines are precision-engineered and need high-lubricity oil to reduce wear. If you use the wrong oil, such as one with too low viscosity, the engine may produce noise during startup and even accelerate carbon buildup. I change the oil every 5,000 to 7,500 kilometers to maintain stable performance. In winter, the low viscosity of 5W-30 ensures smooth cold starts. Newer models may recommend 0W-20 for better fuel efficiency, but always check the owner's manual to confirm. Long-term neglect can lead to skyrocketing repair costs, so it's safer to buy certified oils from brands like Shell or Mobil.
