What type of engine oil should be used for Audi A4?
2 Answers
Audi A4 originally uses engine oil that complies with VW standard 502-00, with a viscosity of ASE-5W-40. Approximately 5L of engine oil is required for maintenance replacement. If maintenance is not performed at a 4S shop, attention should be paid to whether the engine oil used is of inferior quality. Below is additional information: 1. Engine oil selection for Audi A4L: Although there are no requirements for the brand of engine oil for Audi A4L, it is necessary to choose engine oil that meets the specified standards. Audi A4 is equipped with a turbocharged engine, so fully synthetic engine oil should be selected. Additionally, choose 5W-40 or 0W-40 engine oil based on the minimum temperature of the region. If possible, engine lubrication system cleaning agent and protective agent can be added to clean the debris adhering to the engine components, which can reduce engine part wear and extend the engine's service life. 2. Engine oil brands: Currently, the best-selling engine oils on the market are Mobil, Shell, and Castrol. You can choose Mobil's Gold Mobil and Silver Mobil, Shell's Blue Shell and Gray Shell, or Castrol's Magnetec and Edge. These engine oils are all suitable. Normally, the engine oil should be changed every 5,000 kilometers. If fully synthetic 0W-40 engine oil is used, maintenance can be performed every 7,500 kilometers.
I've been driving an Audi A4 for over two years, and during maintenance, the technicians always emphasize using 502 00 standard engine oil. Factory-recommended 5W-40 full synthetic oils like Mobil ESP or Castrol Edge with VW certification are particularly good. For newer models with particulate filters, it's best to use low-ash 0W-30 oil to reduce clogging risks. Once I used regular oil, and the engine noise became noticeably louder with acceleration hesitation. During every maintenance, I carefully check the repair order to confirm specifications since the EA888 engine is particularly sensitive to oil. Actually, when buying oil, looking for the ACEA C3 standard is always a safe bet—don't skimp on a few dozen bucks to make the engine suffer.
