I just got my test results back from Blackstone Labs and they are kind of scary. Eric, from Blackstone, was not aware of the GMC Motorhome group, but promised that he would check with others to find how to add my data to the group database.
This is my first test since bringing her home from Ohio last October. I have no idea how old the oil was before getting to Tom Hampton's place in Ohio, but the oil was changed at his place (Mobil 1). On the road back I added other synthetics as needed. Now I carry Mobile 1 with me in the 5 quart jug.
I'll pull another sample when I change the oil after I get 2,500 miles on this oil and hope for good news. During the time this oil was in the motorhome I had trouble with an electric fuel pump that caused the carb to run very rich, so that may have added unwanted bits to the oil.
Thinking of Dan's recent unpleasantness I have about 700 miles on the oil change and the oil is still very clean looking.
Eric promised that he would send me additional information once he finds out about our GMC Motorhome database.
