You may want to consider both an oil and an additive to replace the now
missing zinc that has been removed from formulas. Lucas has a good
additive IIRC. Virtually any engine with flat tappets would benefit from
such an additive. However, if you are not driving a lot, (say only a few
thousand miles a year) virtually any straight 30 weight oil will be fine.
Recalling what used to use in my father's 62 Chrysler and my 69
Plymouth, I'd guess about any 10w-30 pr 10w-40 would be fine. Only
if you're in a very warm climate would I go anything as heavy as
straight 30. No, it won't "burn," but no, it won't lubricate nearly
as much during the first few minutes of a cold start as a lighter oil.
The heavier weights were popular with people who survived WWII and
didn't want oil burning at all during the shortages. However, they
didn't realize that their engines--particularly the main and rod
bearings--were wearing a lot more during the first few minutes of
My father used to tell me to run the engines right on the "add oil"
mark so the oil lasted longer. I used to tell him the war had been
over for twenty years and I wanted the engine to last forever. Back
when the assumption was you only could get 100,000 miles out of an
American V-8, I got 145,000 out of my Chevy wagon on 10w40 without
burning a quart between 3000-5000 mile oil changes--and fell prey to
"I want a mini-van" and traded it off before I knew what it really was
going to do.
