How many liters of engine oil should be added to an Audi Q5?

The recommended engine oil capacity for an Audi Q5 is 4.6 liters. The original factory oil for Audi is SM-grade synthetic oil. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The recommended oil specification for the Audi Q5 in the manual is 5W-40. Any oil model that meets this specification can be used. 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, and the smoother the cold start of the car will be. The second number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil can maintain its viscosity index at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in an Audi Q5 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 and let it run for 30 seconds to allow the oil in the main oil passage to drain; 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 oil through the oil filler cap on the engine valve cover. Generally, fill up to three-quarters of a standard oil container; Start the engine and let it run for 5 minutes. 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 oil dipstick and check that the engine oil level is within the standard range.
When I first bought my Audi Q5, I was also confused about how much engine oil to add. The manual states that changing the oil along with the filter requires about 5.5 liters, but the actual operation depends on the situation. During my last maintenance visit, the mechanic drained the old oil for 15 minutes, replaced the new filter, and then added 5.3 liters of new oil. After starting the engine and letting it run for two minutes before shutting it off, we waited for the oil to settle and checked the dipstick, which showed the oil level slightly below the minimum mark. We then topped it up with an additional 0.3 liters to reach the middle of the scale. Never fill it up to the maximum line, as overfilling can cause excessive crankcase pressure, leading to oil leaks or even engine damage in severe cases. If the oil warning light comes on, never continue driving—towing it to a mechanic for inspection is the safest option. I always supervise the mechanic during maintenance to ensure everything is done properly and to have peace of mind.
