Sent my first sample from the coach to Blackstone.
http://www.gmcmhphotos.com/photos/oil-analysis/p67855-oil-analysis-redacted.html
This analysis is from the first oil fill after purchasing the coach last winter (I changed the oil in March and this is the oil that was put in at that time). I know that the coach accumulated just a few miles over the course of the last 15 years, and as far as I know the oil that was in there before march had been in there the whole time. I do NOT know if the PO ever started and ran the coach or if it just sat. Never got to meet PO, coach was bought at auction yard. I did not bother to pre-oil as the coach had been driven onto and off of the trailer to get to the yard (and I probably wouldn't have had the wisdom to do that at that time anyways). One note: I found out during that oil change that the dipstick was incorrect. I estimate around only 2.5 quarts actually came out of the pan/oil filter. The coach was driven a few times to test things before I discovered this, including on the highway. I was religiously watching the aftermarket oil pressure gauge which was always above 40 at speed and as low as 30 hot idle. Never saw so much as a blip. Since then, I am putting 5 quarts in during oil change and marking that spot on the dipstick.
Mostly just bumming out, but I do have one question for the group... I did install new stainless oil cooler lines and an oil temp sensor inside the oil filter adapter (brass piece drilled and tapped into aluminum, obviously cleaned out the adapter before re-installing). Could these high metals be because of this work?
The coach does seem to use some oil but I'm not 100% sure how much since I did drain some of the oil doing the aforementioned work. And obviously I can't trust the dipstick. Compression test last winter showed 150 psi all around. Going to do another one this weekend.
Winter is my slow time so I am trying to figure out where I can drive to get 1,000 mi round trip quickly so that I can get another sample ASAP. All while avoiding as much road salt as possible.
