Can I add 1 liter of oil when the Audi Q5 oil level warning light comes on?

Audi Q5 oil level warning light prompts to add 1 liter of oil is acceptable, but it is necessary to refuel as soon as possible. The following are the effects of adding too much oil and the introduction of oil function: Effects of adding too much oil: Adding too much oil will affect the work of the three-way catalytic converter, and the high oil pressure will cause certain damage to the seals. It will also cause violent agitation of the crankshaft and connecting rod big end when the engine is working, which not only increases the internal power loss of the engine, but also increases the oil splashed on the cylinder wall, resulting in the phenomenon of burning and discharging oil. Function of oil: The engine is the heart of the car. There are many metal surfaces that rub against each other in the engine. These parts move at high speed and in a poor environment, and the working temperature can reach 400 to 600 degrees. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and extend their service life.
When I first drove an Audi Q5, I also encountered the oil warning prompting me to add 1 liter. I just casually poured in a bottle, and the warning went away—pretty convenient. But later, I realized you can’t just rely on that. You should first park, turn off the engine, wait a few minutes, and check the dipstick to confirm the oil level is truly below the MIN mark before adding. Audis, especially older Q5 models, tend to burn oil. Adding 1 liter might just be a temporary fix. My friend kept doing this and ended up with an oil leak he didn’t notice, costing him a hefty repair bill. So, I recommend driving a few dozen kilometers after adding oil and then checking the level again. If the warning persists, it’s best to visit the dealership to inspect the PCV system or piston ring wear. In short, adding 1 liter can work for short trips, but don’t skip regular maintenance—monitoring oil levels is crucial for safety.
