Your copper and lead levels are exceptionally high; If you are sure your car has no additives I would not risk driving your car any longer.

Not to be alarming, but those might be the highest values of both Lead and Copper in this entire 75 page thread (iirc). Any idea when the last time the oil was changed? Maybe it is the case that the PO has neglected an oil change or 2? I hope things look better on your next analysis. Keep us updated on your findings please. How many miles are on your car (I didn't see it in your post or analysis). Honestly, I'd go ahead and plan on doing rod bearings soon and possibly not driving it until then, depending on the next set of results you have.


Lead is 31.5 TIMES higher than universal averages and Copper is 7.75 TIMES higher than universal averages. Iron is also twice as high as average.

How is the overall condition of everything else on the car? Did it come with many service records? Any driving issues?

Sorry for the less than great news.

Yeah with those numbers, I'd be changing the bearings yesterday. Run the new sample and if the number are still high, just bite the bullet and do it.

Default Re: The Official E46 M3 Oil Analysis Results Thread

I really appreciate the quick response! Just some background information. I just recently purchased the m3 from an older gentleman that knew the m3 was a special car, but didn't know too much other than that. I purchased it with 106k miles and its in decent overall condition. I did get a PPI done at a reputable independent BMW shop and everything checked out okay. I only did the oil analysis just to see the overall health of the engine and for piece of mind to see how the rod bearing condition was. I thought I was in the clear since it was a late model 04+. Luckily I did the oil analysis and I got these extremely high numbers. I only suggest that there is an oil additive due to what black stone said in their comment. The day I got the oil analysis results I hoped on to the group buy for the WPC rod bearings/bolts. I have roughly another 100ish miles before I hit another 1k miles to get the oil tested again. I figure if these values are really this high I'm already screwed as far as the condition of the rod bearing journals so what is another 1k miles. Hopefully this is not the case though. Again, the car is in good condition and I'm hoping its just the fact the previous owner didn't change the oil and used an oil additive. Its been an antagonizing 1k miles. I can count on a single hand how many times I've taken it to redline and this was only when I first test drove the car.

It is alarming, my heart dropped when I got the oil analysis results back. I didn't get much information from the previous owner. I'm hoping its just the fact the previous owner didn't change the oil and used an oil additive. I purchased the car with 106k miles. Overall the condition of the car is pretty decent. I've had two reputable independent BMW shops look at the car. (PPI). The car has no driving issues, no noise (I'm thinking there should be if these levels really are this high).

As soon as I hit the 1k mark I'm parking the m3 and getting the oil analyzed. If the results come back high its getting new WPC rod bearings/bolts the day I receive them from the group buy.

The journals likely aren't screwed until the bearing spins, which you may be single digit miles away from.

I would park the car. If you're not DIYing the rod bearing change, I'd tow it to the shop doing it. I would not continue to drive in any style.

If you want to do another oil analysis before changing them, do it now with however many miles you have-- stop driving. Stop.

Just to add, changing the bearings at 100k is not out of the norm.

And yes, stop driving now.

As already said, you could be an engine start away from a spun bearing. And the journals are most likely fine right now.

Stop driving the car. Why risk it for a round number for an oil analysis?????

It was what was suggested by black stone. They suggested the higher numbers may be from an oil additive (it had other high levels other than just copper and lead)

The risk of testing that is a wrecked engine.
