You're going to get allot of varried input on this subject but.....
Go ahead and run the Klotz it wont hurt a thing , you may have to retune a little but not much
I have run mainly Amsoil 100:1 in all of my engines for years and occasionally i'll run out of Amsoil and have to use whatever is avail.
I have not noticed any concerning issues caused by using other oils at 50:1 or 32:1 ratio (depending on what the oil manufacturer recommends )
You may notice that the air/fuel mixture may be a little more lean with a lower ratio oil mix , you might need to richen your carb settings just a little.
