I changed my oil tonight and am sending it in to blackstone-labs.com. They do a particulate analysis on the oil and tell you the "health" of your motor. Sounds interesting for $20, a guy I work with does this every other oil change with his suburu tuner and says they pick up everything.
If anybody as tried this let me know, I will post my results after I get them back.
