[AT] oil for old engines

[Larry D Goss]

Years ago when I ran a Diesel Mercedes, I read some material about some of 
the fundamental differences in oils.  The Pennsylvania oils, including 
Pennzoil, are particularly high in paraffin.

I understand that'll clog things up real quick when you switch to a 
detergent oil.
