Cooling with oil

[jdbubb at ix.netcom.com (Dan Bubb)]

Even with distilled water you'll still get some corrosion, so you want to
run some amount of anti-freeze if only for it's anti-corrosion properties.
BTW water's specific heat is 1.0. Anti-freeze is .53, so the more
anti-freeze you run the less effective your cooling system becomes. In hot
climates you really want to limit the amount of anti-freeze to the minimum
required for corrosion protection.
