I think you may have gotten the wrong impression about B-P oil. I 
think people here like it and recommend it because of the additives 
it still has that work well with the style of cams and lifters in 
these old cars.  

OTOH, my impression is that those additives are only really useful 
during engine breakin and are not really necessary thereafter. With 
107,000 miles on your engine, you're WAY past breakin.

I would use B-P oil, or an additive with ZDDP, on any engine which I 
rebuilt, probably for the first 10-20 kmiles. Thereafter I think any 
good oil would suffice, but the ZDDP does no harm if used on these 
cars forever. I believe ZDDP was phased out of most engine oils 
because it poisoned catylitic converters. There's no harm in using it 
in cars that don't have them.
