Default Piston slap question

Could piston slap be silenced by using a heavier oil like straight 50 wt .

slap is a clearance issue. using heavier oil may/may not add some dampening.
if it is bad, fix it, only leads to worst things.
ole saw dust in the diff'l is just a band-aide.

I think I’m going to drain the oil tank and then put just 2 Qts of 50 wt in to do a short sound test . To actually see if it makes a difference .
