Important compatibility information

VW 508.00/509.00 is a specialised 0W-20 requirement. Do not assume it can replace VW 504.00/507.00, another 0W-20 oil or a different viscosity grade. Use only when the exact specification is stated for the engine.

Frequently asked questions

Is this suitable for all VW, Audi, Škoda or SEAT engines?
No. It is intended only for engines that explicitly require VW 508.00 or VW 509.00.

Is this suitable for Porsche vehicles?
It is suitable only where Porsche C20 is specified. Check the handbook or service information.

Why is the oil slightly green?
The product data identifies its appearance as a slight green liquid, helping distinguish this specialised formulation.

Can I mix it with another engine oil?
For correct performance, avoid mixing different specifications unless the vehicle manufacturer expressly permits it.
