• A modern lubricating oil has to be multi-functional — in short, required to lubricate engine parts, protect against wear and keep the engine clean, aid starting, and seal and cool, Michael John Paton, fleet engineering manager for Nationwide Contracts, told the London conference of the European Transport Maintenance Council.
So, he asked, what are the problems for the transport engineer? Approximately 40% of the engine — the crankshaft, pistons and gears — are cooled by the A few engine manufacturers have turned to what is perhaps, in his opinion, the most efficient type of filter, the centrifugal filter, not to mention the by-pass filter.
"Surely we must be asking the question, 'Why do we appear not to have progressed in the area of oil filtration'?"
Each year engineers repair engines or worst still replace them, he said. "Many reasons give rise for concern but one which I am sure is low on the list of priorities is oil leaks, that can, and often do result in oil starvation."
