Owner reviews for engine oil

I personally use 5w50 valvoline fully synthetic racing oil for my r56 and change every 5000 km which is like around 3k miles and it's running good

I used Castrol magnatec 5w30 Fully synthetic every 6-7k Miles.

The OE VW oil is Mobil 1 0W-20 ESP X2 with a zirconium marker and blue dye added for VW 508/509 requirements. The ESP X2 0W-20 is the only M1 product that meets the higher HTHS spec needed for VW 508/509. Its also API SP and has balanced chemistry for LSPI issues in other makes.

Mobil 1 5w-50 for the last few years.

I used Castrol edge 5w40 euro car when I had my car.

I also switched to a 50 weight, Redline.

I was seeing moderate oil consumption and the heavier viscosity seems to have fixed that issue

I use liqui-moly 5w50 green stuff supposed to have better wear protection and I also add cerratech to it.

Liqui moly, 5w40

Motul 5w40 X-cess, suggested by multiple reputable indies.

Yes, you can certainly use 506.01 in your TDI and it's used in many TDIs around the world. However, based upon some of the UOAs offered up, I'd suggest moving to 507.00. The 506.01 has shown relatively high wear metals.
