John,
Before jumping to having an onsite oil lab analysis we need to provide a feasibility or project study if this will really be an advantage or benefit. My last work was in a Mining firm before I put up my own organization, our monthly lubrication cost was around P 2,000,000 (pesos) or $ 50,000.00 divide the peso by 48 to get the conversion, but that was nothing our spare cost and overhauling damages such as hydraulic pumps amount to 4 times the cost of lubricants, not to mention other mechanical parts such as bearing seals etc.
In my study in this mining firm the equipment damages and lubricant cost far outweights the total cost of an in-house lab hence management approved it.
What is important in having an in-house lab is to have a feasiblity study and determine the ROI .
My Warm Regards,
