There are racing oils, Royal Purple for one, used by Pro Stock and other 
drag
racers that are very, very thin. Royal Purple has a 0W-10 and a 0W-7.
I would guess at 80 degrees the oil was as thin as 5W-30 is at 200 degrees.

The old Indy Ford V-8 (non turbo) owners manual called for 180 water and
160 oil before cranking the motor. The oil specified was Ford Rotella(sp)
20W-40.
