"Within reason, thicker oil generally seals better and maintains a better film of lubrication between moving parts."
I like this quote from PM. approved

Also, if the oil is too thick the engine requires more energy to turn the crankshaft, which is partly submerged in a bath of oil.

O RLY?

On the big locomotives, when they are shut down, generally the crankshaft is partially submerged in oil. When it is really cold, -10 to -20F., you can hear the crank slapping the oil on start.

I guess this is the "passenger car" section!

It's all about balance. As thin as possible-as thick as necessary.

Ummm...nope, one should check the current edition of J300 to see WHAT the current W ratings are, but that's not it.

Locomotives don't have anti-freeze in their cooling system and have SAE 40 in the sump, so how do you start a locomotive at -20F? Which locomotives are you referring to, EMDs or GEs? I wonder how far the crank is from the oil level when the engine is not running?

Same engines in boats, just in case your locomotive won't crank at -20F.

Unfortunately in the U.S., EMD can't sell the 710 in a locomotive as of 2015, because of Tier 4 emission standards. They now have a 12 cylinder version of the H engine from the 90MAC in the 70ACe T4.

If it has been sitting, the water is dumped. You fill it up with hot water and start. There was this a switcher (GP40) that had been sitting for a week in real cold weather. It was in the minus teens. I sprayed the engine with hot water for an hour to get it warmed up. I was a solid sheet of ice. The EMD two strokes and the GE FDL engines are the crank in the oil engines. The GE EVO's cranks are higher up from the oil. If you are familiar with the engine, you know where on the crank to fill it when changing oil, without looking on the dipstick.
