I've used 3-in-1 Oil, ATF and 30wt.
This is a little like the old argument during The Dark Ages; how many Angels
can dance on the head of a pin.

I used Marvel Mystery Oil in mine.
I figured if it got sucked into the intake it would be good for the motor.
I used ATF, 30wt, 10wt (compressor oil), at various times or when
nothing else was at hand.
Just make sure you use the same in both carbs, if you have two.
