I'm not sure, that is kinda weird. Nickel is used in bearing coatings, but I'm not sure if the S65's have any. It's also an alloy for valves, the crankshaft, and camshaft in some cars. Again, not sure where the S65 used nickel. In previous analyses, did you have any nickel show up? If you don't have any previous reports, I would just keep driving and monitor things. If the nickel is elevated from last time, I would watch closely on the next one.

BMW hasn't used Nikasil for a long time. The rise of nickel over time is suspect given that your change intervals appear to be similar. Also, to be clear, are you really adding 5 quarts of oil in between changes? That would mean you're burning almost 1 quart per 1,000 miles driven. How did that suddenly happen in early 2016? You may want to post this on BITOG to get some other opinions, but something is wrong if the car is burning that much oil and has nickel rising over time.

That being said, the car has been fairly consistent at 1200 mi / Liter......so am chalking this up to how some S65 motors consume oil. |

Wow a liter per every 1k is huge especially w/ 10w60. Bad piston rings or valve seals maybe?
And for myself, as I'm considering cashing in my warranty, at what range of lead levels are considered high? |

Every engine is different. Some will consistently show 0, so anything >0 is considered high, and others will consistently show 10, so anything above 10 would be high. This is why you want to do reports over time and establish a baseline.

Cams are a high nickel steel alloy IIRC, but I would think you would also see more chrome if it was cam wear and that's a zero (chrome and nickel content are around the same approximate concentration in those alloys)

Am I reading this right -- you only drive 2,000 miles a year? Pay for TBN & TAN next time. I'd be curious to see what's happening there. You could try calling Blackstone to see if they have enough left over to run those for you.

Just bought the car about 2 weeks ago and asked the dealer to collect an oil sample before they changed out oil pre-sale. The report seems good, I was nervous about it.

Attached are the results of the first 2 UOA's on my 2009 M3. Following are some notes:
I would appreciate any thoughts on these results. Cheers, Doug |

BMW Twin Turbo Power 10w60 VOA
Here's a VOA of the oil that I understand went into my S65 in June/July 2017. I had Blackstone re-run the viscosity with it coming back the second time at 21.84cST @100C. UOA coming shortly.

Since I got 8 qts redline 10w60 lying around, I might try with 2 qts of redline 0w40.

My 2nd oil report. Not bad, i guess the iron is high since I've been using the old girl as a daily than the previous owner. So far so good! I changed the oil to the Shell T6 so we'll see in 6k how the report on that is.

Acquired a new to me 2010 BMW e90 M3 with DCT. The same day I changed the oil. In retrospect shouldve gotten a sample done with whatever was in the car when I got it.
Spec: 10/2009 Production Date Mileage at Test 90850 Mileage on oil ~5600 Motul 8100 X-power 10w60 Mostly highway miles for now. I will be doing a test every oil change to verify consistency in numbers. |

This was a 10k oil change run
