Hi Fred,


You'll get lots of opinions (the List has been slow lately ;).  I've 
done some research and given it a lot of thought and have come to the 
following conclusion: if you drive a lot of highway miles--say, 2K+ a 
month (not likely with a Healey)--then synthetic would be cost effective 
and labor-reducing with extended oil changes (6K+ miles).  If not--i.e. 
you do more "city" driving and put less than 2K miles a month on your 
car--then use mineral oil and change more often (3K miles).  I do use 
synthetic oil in the gearbox and differential of my Healeys, however.  
My new Mustang calls for semi-synthetic (5W-20!)--which is a reasonable 
compromise and I can get it for $2/qt--and 7,500 mile oil changes (no 
way I'll go that long--I do mostly city driving with it).

Bottom line is mineral oil and synthetic both accumulate moisture and 
acidic compounds, especially from city driving (short trips).  Best to 
change a "city" car's oil every 3-4 months regardless of miles, although 
I go longer with my Healey because I do almost all highway miles in it.

BTW--whatever you think of WalMart--they have the best price on oil that 
I've found.
