oil usage

[Alexei M Voloshin <Alexei.M.Voloshin-1@tc.umn.edu>]

I would think that engines in good condition should use no or a little oil.
How little primarily depends on the size of the engine and the manufacturer.

Also the change in oil usage of the engine is much more important. If 
your car burns 1/2 quart/ 3k miles consistently then I would consider it 
normal.
But if one day it starts burning 1 quart per 3k instead of the usual 1/2 
quart, then I'd think there is a problem somewhere. 

Just as a reference:
All of the 5000 TQs that I had burned about 1/2 quart per 3k consistently.
91 100 Auto does not burn any at all at 87k.
My 88 Legend with 146k does not burn any oil either.
