Liqui-Moly Top Tec 4200

I've read and heard lots of good things about LM's Top Tec 4200 oil but I'm curious; is it a full synthetic or a synthetic blend motor oil? If it's a full synth, what base oil is used?

If you look at how they position on their web site, I believe LM is saying it a full syn, but not a pure syn.

Actually, I did a little more research and it seems the HC used in their description is short for hydrocracked; in essence this oil is derived from a group 3 mineral base. To be considered a true synthetic, it would have to be formulated from either a group 4 or 5 base.

What I do find interesting however is LM's VI of 175 which is higher than most competing "full synthetic" 507 approved oils. Still, I wonder what a long term UOA will show with the LM. I've seen a few posted here and they look good, but I believe most were analyzed with less than 10,000 miles on the oil.

ETA: Found a video on Youtube that describes the differences between HC group III vs PAO group IV pretty well. Disclaimer: it's done by an Amsoil rep.

Any other comments about Top Tec? I assume not too many people here use this oil. I didn't find too many UOAs posted.

I use it because I watched a video on youtube about their business and like their owners. car seems to run great on it.
