Background:
2000 VW Jetta VR6
Purchased car feb '04 49950mi
changed oil to M1 0w40 at 52000 mi
Not sure about previous maintenance, the car was leased.
NYC non daily driver, no stop and go... but most trips less than 7mi.
At 4900 mi, I changed the filter, and added .75qt make-up oil. Took a sample then (from the filter housing) to send to blackstone. Results below (no TBN).
At 6750 mi (1850 mi later), I changed the filter, added .75qt make up oil and 12oz Auto-RX.
At 8250 mi (1650 mi later) I drained the oil and took a sample.
Was all set to send it in to be analyzed (Dyson?) but am now thinking that it might not be all that useful to know what's going on at this point. Thinking that maybe I should just hold off, testing whatever oil I put in after the rinse phase.
Thoughts? Advice?
