Subject: a clean-burning oil?

Hello;
After the first tune-up on my '71 Ambassador,it was revealed that I was
getting some "oiling" into the port-side cylinder, compression 125lbs.
Mechanic showed me the plug was running more foul than the right cyl.He
then installed a plug one heat range hotter to that side.( BP6E7).
My right cylinder is 131 lb.& the exhaust pressure coming from that side is
detectably snappier than the left during idle & throttle-blipping.
Bike runs OK, if a little lumpy at lower rpm., occasionally stumbling into
a stall if I let the revs drop when well-heated at an intersection.
My question is (are):
I am also using a graphite based oil additive which I've been happy with in
my old Subaru, but maybe I shouldn't if I've got some burning oil in left
cyl.
With more suspended solids in the lubricant, maybe I'm plating crap onto
the electrodes faster than I need to be.
Has anyone a clean-burning (oxymoron) oil to recommend to minimize
oil-fouling of a plug?
Any other suggestions to keep plugs cleaner longer?
I'm considering that the bike may need a small to medium trip to the
hospital this winter for top-end work like rings/valve- guides, examine
pistons etc.
Even with my relatively minor problem stated, this motorcycle blasts along
nicely on the highway... much surprising 2 friends of mine with newer more
expensive riding-iron. in truth they are both a bit perturbed that my Guzzi
has the most interesting exhaust note.
