Blackstone Laboratories Oil Analysis
I finally sent out my very first sample of oil to Blackstone Laboratories! Having seen a handful of members coming up with less than desirable results, I was a bit nervous. I did have the Rod Bearing Recall nearly a decade ago conducted by my local BMW dealer. Despite that, some race shops have told me that they are not permanent fixes. In the end, I am rather thankful that my results came out perfectly clean!
Over the 11 years of ownership, I have always done oil changes every 7500 miles. It was only the past year or so when I started changing oil every 5000 miles. To the say the least, I am very pleased with the results. I was actually preparing to do an rod bearing upgrade, but I may postpone those plans a bit further.
