How would you pros advise on oil, filters and maintenance on my 1962 Lincoln. Currently using VAlvoline oil 10/30 but break in was with all Amsoil products for the first 5000 miles. It uses no oil, and has 120,000 miles on unit. Since rebuild, it has travelled 24,000 miles. A friend has been suggesting I switch all my cars to Schaefer oil products which I am open to pursue. What would you do? I live in Az, and it is known to get warm here.
Thanks KD
