Hey all, long time lurker, new poster. Did a UOA on my 2015 GTI I recently purchased. I believe it to be Castrol 0W-40. Car is Tuned stage 1 plus by Unitronic and is full bolt on Will be using Mobil 1 0W-40 FS like I have on my past 4 VW's and 2 Saabs at 5K OCI [Linked Image]uoa111 by tjbell88, on Flickr

Looks good really good. I doubt the wear metals will look this good with the M-1 but a few ppm of wear metals in a UOA are worthless.

Would you recommend something else? The previous owner used Liqui Moly 5W40 leichtlauf

Just check what oil VW specs for that engine and make sure the oil has that approval. That high pressure fuel pump is a problem area and is lubed by the oil.
