Which engine oil is best for Audi A3?

[AlessandraAnn]

Audi A3, both 1.4T and 2.0T models use 5w40 (5L) fully synthetic engine oil with a replacement interval of 10,000 kilometers. You can choose international brands like Shell, Castrol or domestic brands such as Great Wall, Tongyi and Kunlun. Below is the replacement method for Audi A3 oil filter: 1. Remove the engine cover. (Simply detach four clips) 2. Use a lift to raise the vehicle or employ an electric oil pump for direct extraction. Remove the dipstick, insert the extraction tube into the dipstick port - the tube must reach the bottom to completely drain the oil. The extraction process takes about 20 minutes; collect the extracted oil in an old container to prevent pollution. 3. After oil extraction, use a socket and wrench to remove the oil filter, clean any excess oil at the contact point, then install the prepared new oil filter. 4. After adding new oil, check the filling quantity using the dipstick. When pulling out the dipstick for the first time, wipe it clean with a tissue before reinserting; the second withdrawal determines the oil level. The dipstick has upper and lower limit marks - the oil level should be between these two marks for normal operation.
