Real Time Oil Analysis
 Is it important?
 Does anyone really want it?
 Is it possible with current technology?
 Is the cost too high?
 Are the devices too bulky?
 Is there a viable solution?

Formula 1
 No real time oil analysis
 Track side analysis
 Over 500 sensors on each car
 Oil from car tested using X-ray
fluorescence spectroscopy
 “That’s the holy grail” Mike Copton, 2004

Economics
 Change the lubricant too early and you will waste
money:
• Replacing oil prematurely
• Taking vehicles off the road too often
 Change the oil too late and you will waste money:
• Higher fuel bills
• Risk higher maintenance costs

Economics
 Estimated direct and consequential
annual loss to industries in the USA due to
wear is approximately 1-2% of GDP.
(Heinz, 1987)

Silicon detectors
 Silicon X-ray Detectors
 Good spectral response
 Operate cooled < -20°C

Summary
 Real-time oil analysis would provide monitoring of
key contaminants
 In-situ robust device operating reliably at high
temperatures
 Accurate measurement would ensure optimum oil
change
 Economic and environmental benefit
