Yes, very nice to see good numbers come back. Won't be concerning myself with rod bearings for quite some time.

Here's my Blackstone report, oil intervals at 5k, using Liquimoly 10w60. I just sent a mid-interval sample to be tested, I guess all is well. Stupid bearing wear is making me paranoid.

You have a bad data set. That's the only conclusion you can draw. Your oil collection technique obviously differed from the standard method. So data not really comparable to most of us that collect it the normal way, from the drain plug.

Oil analysis attached. Just bought this car about 3,000 miles ago and had the oil changed. Anyone know if I should be worried about the elevated lead level or the flashpoint? Anyone know what the decreased flashpoint means?

Flashpoint is probably low because of the fuel dilution.

Blackstone Report at 135000 miles.
12500 miles on this 10w-60.
"JOHN: Wear metals are very low and consistent in this sample from your M3 and that's really nice to see. The low wear is especially impressive considering how long you're running the oil. This is more than twice the number of miles that universal averages are based on. Not only is this engine producing low metals overall, but it also produces metals much lower than we see on average from the S65. You can't beat that. No excess fuel or harmful coolant showed up and the viscosity is in the 10W/60 range. Air and oil filtration are excellent. Keep up the good work." I bought this car from Paul Walker with 54000 miles on it. I would post the entire report but my PC is not working as well as my S65. |

Can someone provide feedback on my first BS report? From the other reports I've seen, my lead levels seem high, considering the mileage of the car - 26,800.
Last oil change was 6,500 miles ago. 2008 E92 M3 DCT on Castrol 10W60, but just switched to Mobil 1 0W-40.

I don't think any decision you make from here on will be based on the feedback you get from the "so called" experts on this forum. Make an informed decision. If you think the 12 ppm of lead is a concern for you, make a decision on your bearings - having it replaced. This is your car - remember. Good luck

It's about trends in metals as well. You need a few reports to see a trend.

Rich,
Looks like TWS is protecting fine when it's all warmed up, but you have cold start wear issue. Thick oil like 10W60 and soft lead based bearings are not the best combination. You'll definitely see less lead now that you switched to 0W40, which is half as thick as 10W60 when you start the motor. |

Posted this a while back but created my own thread forgetting to post it here. Last time I posted it people just said my lead levels were concerning but that's kinda where it died. I have gone the way of Mobil 1 0w-40 this time around in hopes that I bring those levels down.
Also the copper, is that just in the oil? I know once your bearings are toast they have a copper appearance right? So your copper levels would be super high if bearing was compromised on its way to failing? I'm still within the unit averages and hope that means I'm ok for now. I think though in the past I was running super rich due to my O2 sensors and spark plugs being compromised. Since I replaced them my car feels completely different in its throttle response and get up to temp much faster. Would running rich cause bearing wear to increase or decrease? Perhaps one does not correlate with the other. Any insights would be appreciated.

You might want to delete your personal info. Copper seems fine. Running rich might cause bearing wear if you were running so rich as to cause fuel dilution of the oil, which doesn't appear to be the case according to your report.

yes, your defective O2 sensors caused the car to run rich, so rich that the fuel diluted your oil..shown by the low cst. Is it the sole cause of your high lead count? I can't tell you for sure, but your lead count is high compare to your last run and the universal average.

Just received my oil analysis after the US Post Office sat on it for nearly a month...
Numbers were really good. Sorry about the poor quality scan.

First report, been running Supercharged with WPC treating bearings and ARP rod bolts for last 16,000 miles. This is from last oil change where I was running castrol edge professional 10w 60, switched to Motul 5w40 so will be curious to see how it does in comparison.
Great oil report though, especially considering my stock bearings were shot to shit at 30k stock engine!
