Another Blackstone Analysis

I received my first Blackstone analysis today and it wasn't exactly what I was hoping for. My car is a 2009 with just under 39,000 miles of which about 6,800 have been supercharged. Everything was normal except for the lead which was 20 as opposed to the average of 7. The description given was this:

"The far right column shows typical wear for a BMW S65 engine after about 5,700 miles on the oil. You kept this fill in use a little longer and the only metal that read out of line was lead. You probably won't like the sound of it, but it shows bearing wear. The good news is that since other metals were in line with averages, it might not be a problem. It could simply be from a temporary particle streak, and if that's the case, it should clear up next time."

I did a search and there are people with significantly higher numbers but I couldn't find any in this range. I did switch to the Mobil 1 0W-40 for this change interval. Should my sky be falling?

Saw one today from a 2009 that had 12 for lead.

We had a customer switch to 0w-40 and his analysis showed elevated aluminum.

My goal was to wait and see what the generally accepted "best" solution to the replacement bearings was before going down that road. I wish I had a better understanding of how bad is a 20 and how long before something bad happens. As they said maybe this was an anomaly but I won't know until my next oil change. Their explanation of a particle streak could easily be the culprit. It is too bad that there is no easy way of knowing.

I'm also waiting to see a definitive fix before I crack open my engine for no reason.

My recommendation is to run 0W40 for 3k miles and do another oil change. I would expect lead levels to go down. Then go from there.

I also got my report today. My car is 2011 with 27000 miles, it was done before i had the super charge installed, now i have 2500 miles on my supercharge. Here is what they found "No problems to report with this M3's engine. Universal averages for the 4.0L S65 engine are based on ~5,700 miles of oil use, and while we don't know how long the oil in this sample was run, our guess is that it's pretty similar since all the wear metals here are right in line with those average levels. However long the oil was in use, it would probably be okay to add a couple thousand miles to the next fill -- that might lead to a little more iron, but as long as everything else holds fairly steady, it's not a concern. No moisture, dirt, or fuel was present. Great report!"

Just got mine as well. I have an 2008-E90 with 28K miles. Here is what Blackstone said:

"You're interested in rod bearing wear and we don't blame you since that's a common issue with some BMW "S" series engines. You'll be pleased to know that your bearings look good since we didn't find much lead or copper in this sample. They'd read higher compared to universal averages, which show typical wear for a S65 after about 5,600 miles on the oil. We don't see any signs of mechanical fatigue in this sample, nor did we find any contamination. The viscosity was on target for a 10W/60 and oil filtration was great (see insolubles). Check back to build wear trends."

I noticed that the only elevated metal in the Blackstone report was molybdenum (about 2.5 times more than the averages). Don't know what that means but I was happy to see the reading for lead and copper at 3 (for both) which is lower than the averages.

BTW I just switched to Mobil 1 0W-40 as well. I don't track the car but I do take it for "spirited" mountain drives. We'll see what the next report says and depending on that I'll make a decision on whether to SC or to sell.

I don't think the op was looking for people to post their normal analysis in his thread discussing elevated lead.


Is there a con census for those of us with new bearings on what metal if any we look for in oil analysis?

Has he posted the report anywhere?

Moly is from the oil, so you have nothing to worry about there (it's actually a good thing). For your 08, the lead and the copper is what you have to worry about, and your levels look good.

My aluminum went up 1 ppm after I switch to Mobil1, but it was still under average so no problems here. Lead ppm dropped, and the car was spanked on pretty hard.

Me too. Hmm.

Got mine today with very similar results. My oil change was at just under 11K mile mark (overall mileage at 53K on a 2008). Lead was 18, everything else was well below average (including Copper at 3). This was the first time I've sent oil in to Blackstone for analysis.

"For a 10,723-mile oil run, your M3 looks pretty good overall, although lead is above average, and that's a possible concern. Lead comes from bearings, so this could be a sign of trouble brewing in that area, but it could also just be a temporary particle streak, so as long as the engine is running well, it's just something to watch for now. Universal averages are based on ~5,700 miles of oil use, so the rest of your metals are impressively low after a longer oil run, and that's a good sign that the lead may not be a serious issue. No contaminants found. Check back."

Next oil change will be no later than 7000 miles from this last one... and I'll continue sending in samples for evaluation. I'd rather know the bearings are going out than be surprised by it.

OP, you must have missed my 37. I also recall seeing someone who was close to 100. Mine has been decreasing over time and my last sample showed 22.

Have you changed your oil habits?

Nope. The only time anything oil related was changed was when I bought the car (prior to the 37 analysis). The previous owner was following the recommended 15K interval. I roughly halved that.
