This is from a BMW S54 engine with 94k miles. I just bought it 3k miles ago. The engine looks reasonably clean under the valve cover so I think it's had regular oil changes. Not sure what's going on here though. Any thoughts?

I bought this car last fall with 91k miles and immediately changed the oil, that is the first sample. I have no idea what oil it was or how long it had been in there (not long judging by TBN and visc), but it most likely was Castrol Edge 10W-60 or Motul 10W-60 with remnants of Ti from a previous...

Here is the latest UOA. There was a lot of idle time and bumper-to-bumper NJ/NYC traffic. First sample was M1 FS 0W-40 after unknown 0W-20. Second sample is ESP X3. Third sample is ESP X4. Interesting that the ESP X4 has almost the same levels of ZDDP as the FS now.

I noticed a lot of Red Line products have become unavailable, even directly, like the Assembly Lube, some High Performance oils, etc. I assume this is related to the operational relocation, but it doesn't give much confidence. This has to be temporary, right?

Sample 1 is FS 0W-40 (visc low from residual 0W-20). Sample 2 is ESP X3 0W-40. 5k miles but a lot of idle time and traffic. Looking good, TBN a little low but didn't do VOA so it might start low. Held viscosity really well. Removed unit time because it's wrong.

6600 miles, lots of short trips and some idling. Plus some hard driving.

I didn't enter the info and this was the first analysis so ignore the comments. Ti is obviously the Castrol additive. Oil was dealer fill TPT 0W-30 LL-01FE. Wear seems a bit high for about 3k miles. Combination of short trips and driven hard (when fully up to temp). Had exhaust side lifters and...

I have a brand new Mazda3 2.5 (MZR 2.5 engine) which calls for 5w-20 and I'm thinking about doing an oil change at about 2k (manual calls for 5k, no special break-in). I just came out of a car that had 2x the power and an 8k redline, so I'm finding myself driving this car pretty hard and maybe...
