Blackstone Labs report
I recently did my first oil change after owning my 2006 M Roadster for a little longer than a year. I do not have a lot of information about the car's history other than the carfax report, which shows the previous owners routinely had it serviced at BMW service centers and it was sold as a CPO vehicle before I bought it used at a BMW dealership, Classic BMW Plano TX.
I have no idea if the car has ever been on a track, but I think it's reasonable to presume it has been "driven spiritedly," as one does with such a car. I got the Blackstone labs report back today, and it seems like the lead is high. They said I should follow up in 3000 miles and be mindful of any unusual noises. Anything else I should be aware of? I know lead and copper in particular are indications that the bearings need to be replace. I presume lead is cause for concern, while copper is the canary in the coal mine? Is there anything else of which I should be aware? Any insight would be greatly appreciated! Thanks in advance. |

I would drive it very gently for 3000 miles and then get another report.
In the mean time, start planning on having the bearings replaced.

You can waste another $30 on a report but it won't change anything. You need new bearings. I just did mine in March and they were terrible.

With 73K miles and that report, I'd bite the bullet and change the bearings out. It's worth the piece of mind instead of constantly worrying about rod knock for 3 months. Oil is a contentious issue, but the S54 is one engine I wouldn't run anything but 10W60 in.

A good lead reading is around 5; I was under the impression that a bad lead reading was something like 10-20. 102 seems impossibly high for bearings, leaded race fuel seems like a reasonable explanation. My biggest fear now would be, if it was leaded fuel, how long for that to fully flush out of the system so that you can get accurate readings again?
Maybe a couple quick back to back oil changes to flush the system? |
