Blackstone Oil Report @ 84K
 

Just wanted to post some engine oil data points - first analysis on the X.

2004 X5 3.0L @ 84,500 miles

Blackstone summary:

At 84,300 miles, you've got a very nicely wearing M54 powering your X5. Universal averages are based on an oil run of about 6,200 miles. That's very close to what you ran, so wear should look similar to averages and it does for the most part. Iron was a little higher, but not high enough to call a problem at steel parts. We'll keep an eye on it next time. This sample of used 5W/30 was free of fuel, coolant, and moisture. Your air and oil filters are getting the job done with both silicon and insolubles reading normally.

Obviously I was very pleased with the results and plan to self service every 6K with M1 from now on.

Not braggin' - just wanted to contribute back some info to a dynamite user forum that has helped me save a TON of $$$ through great DIYs! Thank you to all the E53ers at XOUTPOST!

Thanks for posting.

Can you scan and attach the actual report?

Did Blackstone tell you what they are using for their universal averages? I am interested in how closely that description matches your vehicle.

PDF report attached. BTW I use Mann oil and air filters...Chef K

Thanks for sharing. This is reassuring. :)
