We have stationary EMD engines in standby power service. Technical Publication M.I. 1760 covers the lube for these units. They reference M.I. 1752 for locomotives so I'd check that also. We use Mobilgard 450 because of the issues with zinc and the silver plated bearings in EMD engines. rgf
Does anyone have thermal breakdown data on the Mobilgard 450. We have a fleet of diesels and use the 450 NC, but plants want me to raise the allowable operating temperature of the oil, so I am looking for any analysis which shows when the thermal breadown begin and the effect on other properties relative to temperature. Any ideas where I can find this data?
