Synthetic oils that meet 502 specifications
The 502 VW oil specification is a standard for a high performance engine oil for VW gasoline engines. This specification has also been adopted by other European car manufacturers, such as Skoda and Audi. Advances in synthetic oil formulations led to a revision of the specification, now called VW 504, which has the same performance characteristics, but has no additives that will significantly improve the time that the car can go between changes. Most commercial synthetic oils will list which standards are compatible with the label, for the purposes of your VW engine, 502 and 504 are equivalent oil types. Compatible with BP (British Petroleum) Engine Oils.
Among the British petroleum oils that meet the class are the BP Visco 5000 brand, the BP Visco 7000 Sport, and the BP Visco 7000 Turbo
Diesel Sport - these are all 40 weight engine oils. BP changes the names of its oils in different countries, BP EuroSpirit, BP Visco 7000 and BP Visco 5000 C are alternative names for these types of engine oils. See more at castrol edge vs mobil 1
