It depends on the oil being sampled and on the volume of oil to be tested. Also depends on how complete a setup you want.
Please note I am working prices backwards from my currency into dollars and so might be way out on the figures.
Spectrometer (or ICP) for wear metal count - $100 000. (we picked up a second hand unused Spectroil JR as a backup machine for $5 000). Note ICP running costs are generally higher, but the ICP is cheaper than Spectroil M for a large amount of samples.
Viscometer - huge selection to choose from, consider the Omnitek S flow >$17 000 (does V100 & v40).
FTIR - not sure of the cost. Digilab is one brand. Think the cost is about $25 000 but could be wrong.
Note that you might want to skip the FTIR and rather go with a soot meter(<$2000), TAN and TBN titrator(<$2000), and Karl Fischer(<$2000) for water. This basically covers the major FTIR bands (except for Oxidation, Glycol(which never works on FTIR) and nitration). Besides a large number of the FTIR readings are geared towards engine oil which might not be what you want.
Software to collate and present data - anything from $5000 to $25 000.
PQ -to measure all metal content above 8µ in size (<$4000). (Not necessarily needed).
Flashpoint tester (for engine oils) - <$3000.
Hotplate - for crackle test <$500.
