[quote]QUOTE: <i>Originally posted by oltmannd</i> <br /><br />Fuel oil: #2 diesel, 37 cetane minimum, cloud point and pour point in winter are usually specified by the individual RR and supplier ususally meets specs by blending with #1 fuel oil. <br /> <br />10 years ago the lube oil was usually straight 40 weight with additive package designed specifically for RR diesels. The RRs were starting to tinker with multi-wt oils at that time. I don't know if they've becomse std or not. Additive package is very high in detergents and buffering agents to keep the pH in range. The GE FDL is harder on oil than the EMD 645/710. It's harder on the pH, dirt load and sheer. <br /> <br />There aren't a lot of grease fittings on locomotives. In fact, I can't think of one off the top of my head. I think most bearings are "greased for life". The toughest grease application is the traction motor gearset. Most new locomotives now use oil, but older ones would take a lithium based grease with an EP additive (usually molybdenum) <br /> <br />-Don <br />[/quote] <br /> <br />you say GE is harder on oil than EMD, what do you mean by that? What does "harder on oil" mean?
