1-Decene, homopolymer, hydrogenated is PAO or group IV. Unlikely there is any significant quantity of group V in this blend.I presume "Distillates (petroleum), hydrotreated heavy paraffinic" are Group III oils while "1-Decene, homopolymer, hydrogenated" are Group IV or Group V oils.
If that is the case, then the Top Tec 4210 0W30 marketed in Germany is a mixture of 20-40% Group III and 20-40% Group IV or V. This is off the German version of the LiquiMoly web site.
I used the Liqui Moly TT 4200 for years in my 2009 TDI and the results were disappointing and it didn’t hold up well. My old UOAs are posted on here. I kept using it because I bought a 20L jug and didn’t want to throw the rest away. I will never buy their overpriced products again.
In my opinion the best VW 507 oil is Mobil 1 ESP 5w30.
