Hi all,
My humble thoughts:
if I had a newly rebuilt engine I'd use a fully synthetic oil like Mobil 1.
For an average engine i.e fairly worn and probably some sludge in there then
a good quality mineral oil is fine. I have always used Castrol GTX 15w/50 in
all my vehicles with oil changes every 3000 miles and a filter change every
6000. I steer clear of really cheap 'supermarket special' oils as I have seen
some sludgy top ends due to this, though in fairness even these cheapos are
probably better than the oils available when the cars were new.
BTW, I must be unique in the world. I have driven LBC's here in the UK for 26
years, all with Lucas electrics, and I have never had a problem that wasn't
down to poor maintenance! If you want really bad electrics buy a Citroen. I
love CX's but the electrics finally made my hair fall out (well, not really,
but you know what I mean).
