I'll confess that I haven't been out to buy oil for about a year. I went
out this morning to a couple of nearby stores, and sure enough, they had
Valvoline VR1 and a couple other brands that were clearly labeled "High
Zinc" or mentioned ZDDP on the label. It looks like a lot of oil companies
are taking the old car/classics/hot rod market seriously. Valvoline
conventional was the least expensive, at under $7.00/qt.
As a side note, I've been using conventional oil because my experience with
old seals and synthetic oil hasn't been good. An oil company rep told me
that in their experience, synthetics have an improved detergent effect that
points up wear in old seals that's been masked by a buildup of
contaminants. It's a theory...
Back to some of the earlier discussions...Correct me if I'm wrong, but
Castrol seems to be the least forthcoming about ZDDP levels in their oils -
I wasn't able to find a table specifying zinc in ppm for GTX. Rimmer Bros.
in the UK sells something that looks like a Castrol for old cars, but I
didn't see that available here. Not knowing, would you want to add ZDDP? I
don't know.
For an MGB with a catalyst, I'd probably think about using an oil with a
known amount of ZDDP (ppm). Some oil companies publish this level. I've
seen between 600 ppm and 1200 ppm. It's sort of a crap shoot with a bottle
of additive, given that you might not know the concentration.
