Abstract : The condition of the engine and transmission oils was determined at three monthly intervals for a period of 24 months for five armoured Leopard vehicles operated routinely by the 1st Armoured Regiment, Puckapunyal. For the trial vehicles, the maximum operating hours was 270 and the minimum 56. All oil samples from the trial vehicles remained within specification requirements for new oil as determined by viscosity, total base number and pentane insoluble content. A small increase in the viscosity of both the engine oils and the transmission oils was recorded over the period of the trial, but all determinations remained well below the maximum specified for new oil. There was no indication of storage or standing deterioration of the oils during the two year period and it was concluded that vehicle operating hours was the sole criterion for the variations that were determined. It was recommended that oil change intervals could be extended to a minimum of 300 operational hours or two years elapsed time....Leopard tanks, Lubricating oils, Engine maintenance.
