Well, I've been a bad boy and haven't paid much attention to state of the art, but I do know that they continue to change the oil formulation and what is good for my 2020 RAV4 would probably cause my 65 to throw a rod in 20 miles. I've not changed the oil in the 65 for several years (it gets very few miles), but its time.
I'm sure its been discussed, but I could not find it with search. Should I:
-- run a diesel engine oil?
-- buy conventional high mileage oil and add some ZDDP additive?
-- spend piles of money on Lucas or Amsoil oils specifically marketed for really old engines?
The engine leaks a little oil from the pan gasket and a little from the rear mail I think. By little, I mean 10 drops over the winter. But I would not want to try a synthetic or probably even a semisynthetic, unless one of you can argue very persuasively.
Thanks in advance, from a long time lurker.....
