RW>I learned the other day that semi-diesels use gallons, rather than quarts
RW>of oil. And that oil will go pretty far because of the same tecniques you
RW>describe above.

And that is why partialy how they can run at 100% power a lot of the
time. The oil does a lot of the cooling of the engine. Particulalry the
piston that takes a lot of heat. Adn most Heavy duty Diesel engines have
jets for oil that shoots up inside the piston to cool the crown
