I think you need to read the book again.  Water is the best coolent of the
three.  Oil is better that air.
Specific heat is the ability of a substance to absorb heat, as relative to
water..

Air = 0.241 BTU/lb/deg

Lubricating oil = 0.46 BTU/lb/deg

Water = 1.00 BTU/lb/deg

It is well know that you will loose heat faster in 50deg water than in 50deg
air.
