View Full Version : Oil choices for an austin healey BN1

05-29-2012, 04:46 PM
i'm looking forward to exchanging emails about my first healey, a 1955 BN1. it's a pretty car, in pretty good shape, and seems pretty primitive now too, in design and build. my british motors experience is that, growing up my folks had a 1958 vauxhall victor, and later i had a 1954 ariel square four for a summer, that i rode out here to california.

my question is- what engine oil seems best for the BN1? my oil pressure is decent, 50 lbs underway, dropping to 20 at warm idle.

i am thinking of using a 15-40 diesel oil, which i understand has more ZDDP, and that without it, internal wear accelerates.

also, what experience is there with sticky additives like STP in this car?
