Re: Auxiliary engine LO pressure drop

[ Edited ]

If condition has only started since engine oil was replaced then was new oil same brand and spec as oil removed ?

for example if engine has been filled with a single viscosity oil instead of a multi viscosity oil (multigrade) then this may explain condition. As engine load increases then oil temperature will also increase and with single viscosity oil the pressure will drop off more than with a multi viscosity oil which has viscosity index improvers in additive package that minimise the drop in viscosity.

Engine LO pressure drops when electric load increased ..engine rated Power 1543KW and alternator Power 1456 .Engine attached pump and Pr.regulator overhauled.Before the issue sump oil was renewed .Kindly advise
Thanks in adavance
