In keeping with my promise, here is the second oil analysis I had done. This was done on April 26, 2005.
The data presented below is from my '94 OHV. The oil used is Amsoil 10W30. The mileage on the oil was exactly 8,054 miles. NOTE that this is TWICE the mileage I put on the last AMSOIL sample. I actually intended to only go 6,000 miles but things got away from me.
The analysis was by Blackstone Labs ( Dead Link Removed )
The first column is my sample and the second column represents an average of data collected for this type motor.

Blackstone Lab's Comments: We were surprised to find a little potassium and sodium in this sample. Unless you've been using Red Line or some kind of additive that contains these elements, we think you're getting a little coolant in the oil. This level is not normally enough to hurt anything, but lead, from your bearings, read higher this sample, too, so we think the coolant is doing some damage. The TBN read 2.1, showing active additive remaining, but we would not advise running more miles until you fix the problem. Suggest running 3000-4000 miles to monitor.
All right, further comments, anyone?? I'm all ears...
