Do you have the owners manual or a Harnes or Clymer?  It usually shows
a chart of viscosity versus temperature range.  The one for my 'S'
does not list 20W-40, but does list 10W40.  The top temperature for
that oil is about 70DEGF.  It also lists 15W-40, with a top temp of >

Given that these engines run hot and lean, I'd stick with what's in
the manal.  I run 20W-50 most of the time.  10W-50 in the Winter

$5/quart?  What is it made of, premium dinosaurs?  Is it synthetic?
How many miles on the engine?
