Liqui Moly Leichlauf vs Synthoil 0W40 vs Molygen (also vs Castrol, Mobil, Fuchs)

I get LM 5w40 for 39.99 cdn here in Ottawa.

Well, so far I am quite satisfied with the Leichtlauf even though I had an extensive communication in writing with LM due to the fact that the stickers on the Leichtlauf somehow lacked VW 502/505 approval. As LM confirmed, it was just a printing error in Germany. However, I did also asked about any Gr. IV oils still available and there are not that many - just a couple of Synthoils like the one above and all of them without VW approvals.
Interestingly, the most cost-efficient I have found so far seems to be the 20L canisters of Pentosin 5W40 High Performance that are avaialble at Rockauto for something like 140-150CAD plus tax and shipping. Pentosin was rated #1 by 540 RAT blog and Leichtlauf somehow ended up being quite mediocre accordingly to his method (like 180 out of 250 oils tested). Hmmm...
Although I got stocked on Leichtlauf at GP.ca for a couple of years.

So who uses the green Molygen around here in their VW? Currently using Leichtlauf.
