Hey Guys,

Anyone else using Blackstone labs or other services for oil & fluid 
analysis?  I sent off samples of oil and ATF from my mom's 2003 BMW 530. 
  She's been going by the dashboard "service soon" indicator, which 
works out to over 15,000 miles between oil changes (!!!)  BMW also 
claims the ATF and differential oil are "lifetime" durable.  I called 
bull on that, and have started doing oil changes for her, and swapped 
the ATF.  Sent samples to Blackstone, actually hoping for some bad news 
to shock & awe her into taking better care of the thing (she intends to 
keep driving it for a good while.)

Amazingly the 17,500 mile oil and 89,000 ATF came back with pretty good 
results.  Anyone else using Blackstone?  Wanna trade notes?  Don't think 
attachments will go through the list server, but if you're interested, I 
can send you the reports off-list, or post on the web.
