This is more of a philosophical question, IMO. Personally, I like to find
the point where I can just force the engine to ping (by lugging it down in
high gear, with it almost overheated; kind of a torture test) and then back
off a few degrees.
But since you are already somewhat faster than the original specification,
and it seems to be working well, there is a lot to be said for just leaving
it alone. Also, to my way of thinking, 14 is already pretty fast. While
going to say, 16, might find another 1% in fuel mileage and power (assuming
it doesn't lead to audible knock); it also risks damaging the starter or
even a piston if you happen to find some inaudible knock.
However, I still recall how I felt after losing a piston to knock I could
not hear (due to other circumstances, not directly from too-fast timing)

so you might say I'm a little gun-shy.
> What kind of oil? 3M, Wd40, 20w50 Castrol?
I generally use motor oil, as I keep a squirt can of it on the bench. WD40
is a poor choice IMO as it is mostly solvent that evaporates and doesn't
leave much oil behind. ISTR the TR3 owner's manual actually mentions some
motor oils as being suitable. "3 in 1" is pretty light, but would probably
be OK.
Just doing the oiling is a lot more important than what you use, though, so
if WD40 or 3in1 is what you have, go ahead and oil it now.
