[Healeys] oil?

[Robert Duquette]

I feel a tad foolish here, but I have to ask . what oil should be used in
the 100's 4 cylinder?  I see that it says S.A.E. 30 in the "Service Manual"
printed in 1956.  I expected to see 20w-50 and Castrol 20w-50 is what I find
in a container in my boot.  ( and it is what I use in my 'spridgets' and
Fiat )

 

Any other fluid/lube recommendations would be appreciated.  ( I'm a Castrol
guy . )

 

Temps here that the car would be on the road would be from just above
freezing to about 35C ( 95F ).

 

Thanks!
