Running Hot...oil that is, good or bad

I just read the same thing last night. Very interesting.

After reading that article I started to think, why do marine diesel engines have oil coolers installed? There must be good reason as they all want to boast about better fuel efficiency and they do everything they can do to cut weight down with higher HP output.

This discussion is a bit over me but I can obviously understand the perks of having warm oil at start up & during the warm up phase. How would having hotter oil (above normal operating temps.) make things better?
Wouldn't the vescosity break down to dangerous levels?

Hi,

I am skeptical of the claims of an amazing discovery.

There is no such thing as "free" energy.

While this might increase gas mileage (less cost), it risks an increase in the oxidation rate of the oil in use which in turn at the very least can lead to more frequent changes ( more cost) lower component life cycle ( more cost).

C4 - L.O. Coolers are used on a Diesel Engine to cool the oil which will be getting heated from the operation of the engine where it is used for lubrication and cooling.

Since the invention is based on reducing the oil viscosity by heating it, it looks to me like you could just use very low viscosity lube oil to begin with and cut out the middle man.

Of course the problem with using very low viscosity lube oil all the time is you will end up with reduced film strength that leads to increased wear, and other issues associated with high temperature operation that will probably cost more in the long run than the savings gained by reducing lube induced friction.
