Oil does in fact play a major cooling role in the engine - it's used to cool down pistons and other hotspots. But yes, water is the major player in removing heat from the engine as a whole. Except in air-cooled motors of courseWas just wondering why they don't use oil instead of water to cool down engines...
Call it a #RandomThought
It's part of a greater whole, sure, but oil is used more to a) counter friction, and b) carry heat to where it can be dissipated by air or water cooling. But that's really over-analysing an Ook[-]Fart[/-]Thought.They do use oil to cool down engines. What makes you think they don't?
Motor vehicles with engine oil coolers use the coolers mainly to keep the temperature of the oil down (to prevent ruining the oil) and not as a means of primary cooling. You will almost always find that these engines use air or water for primary cooling.They do use oil to cool down engines. What makes you think they don't?
Nonsense. Why do aircooled engines have powerful fans blowing on fins on the cylinder heads then?Air cooling doesn't actually cool the engine, but cools the oil going through the engine instead.
Nonsense again.Ever heard of an oil cooler? Those are pretty much found on air-cooled engines only.
