Great write up, went through it all. Looking forward to the VOAs and UOAs to come. Thanks in advance.
Used 5w30 x clean in my 370z, summer car only, racked up 4200 kilometres on the oil. Car was fine with it. The X community loves Motul, my wallet not so much.

Xcess 5w-40 - This was my introduction to Motul. I bought it specifically for use in my stage 2+ tuned 2015 STI. Lots of track use, never let me down yet. Oil temps are very good, Oil pressure stays very consistent right to oil change although I've never gone over 5k kms on it. Very robust TBN at 8.8 and a CST of 13.1 puts it at pretty much dead center viscosity for a 5w-40. Usually change this once a year unless it is tracked as it's a weekend driver.
Xclean EFE 5w-30- I use this I'm my 2006 Pontiac vibe DD and my wifes 2013 Hyundai Santa fe XL 3.3L. Neither of them have burned a drop. The Santa fe is on a 6000km/6month OCI and the vibe I run to 10k kms usually takes me about 4 months. I just changed it in December and when it hits 10K this time I'm going to pull an oil sample through the stick for analysis. Depending on results I'll run it out another 5k and retest. Probably change it around this time. I can't fined a UOA on this one. So I'll be sending in a VOA in the next week. As per the Motul literature TBN sits at 7.8 and the cSt is a 12.1 putting this one at the boarder of a light 40 weight oil.
Motul ecolite 0w-20- Use this in my cousin's 2019 Subaru crosstrek with 56k kms on it. At 1500kms per week I'm changing it every 8 weeks around the 10-12k kms mark. Doesn't use a drop. Oil analysis will be done in the coming year in an effort to push out the OCI on that one after the warranty has expired. I expect to be closer to the 15-20k kms OCI with this one as it's a highway driver exclusively. Will post results when I do. This one has a TBN of 6.2 and a cSt of 8.61
In November I changed the Santa fe to the XCESS 5w-40 to Address a timing chain rattle at idle. I found after the fact that it wasn't really the best choice for the GDI because of its higher calcium rating @ 2447. I'm debating right now what my next move is on that one. I'd like to run it to the spring and take a sample to send off for analysis to see what the insolubles and "dreaded" fuel dilutions are. If it's OK, I might just string it out another 5k. I won't be putting that one back in. Looks like the xclean 5w-40 is much lower in calcium so I'll either try that or go back to the EFE.
From what I've found, looks like xclean is being phased out for the xclean efe 5w-30. Xclean+ will probably stick around as it is the only one in their lineup that carries the
VW 507 approval for the 09+ TDI common rail systems that I've found. I haven't seen anything in my travels by Motul that covers BMW past the LL04 specs.
Watch for my VO/UOAS coming soon!
