Mickey,

We have looked at the bottle of EXS that you are showing in the photograph. Based on the markings that bottle is a 2002 vintage product. All oil products will have some settling of additives over time, especially over a three year period. The additives that do settle out of oil will appear to be contamination and look like what you saw under the microscope. If this oil was introduced in an engine and brought up to operating temperature the additives would go back into solution and we would see a very different particle count. You could in effect demonstrate that the additives would go back into solution by and heating the oil sample to say 150 deg. F while you agitate it for 15 minutes. Take another particle count and see what the numbers look like. This process will assure both of us that what you have referred to as Dirt is in fact additive settling.

I sent a virgin samle of this oil to have it analysed. It seems to have a lot of dirt in it fresh out of the bottle. Any opinions? Thanks Mikey
