Audi A3 oil selection criteria
All oils are selected on the basis of vehicle approvals, SAE, and ACEA compliance.
The VAG approvals are 502.00/505.00 and 504.00/507.00.
ACEA A3/B3 and higher.
The viscosity is suitable for 5W30, 5W40, 0W30. But more often drivers use 5W30.
Information on viscosity for a specific engine can be found in the engine oil interchangeability catalog: https://www.northsealubricants.com/en/oil-advisor.
The catalog can be trusted, as the data are taken from the car manufacturers. Thus it is possible to select not only oil for the engine but also for the gearbox, gears, brake system, cooling system. I.e. all fluids.
