be careful on that 'be careful'... using more oil with the gas DOES lean out the gas to air ratio... BUT.. it is a small effect... less than the effect of one size on a main jet.
So don't overstate that effect... the only time that will have a dmaging consequence is when the guy is already running on the ragged edge.
... its a small effect.
... and I have no problem with a 32 to 1 oil ratio.. at all.
Most people who race 2 strokes run around 32 to 1 ... and there are also misconceptions that running more oil makes less HP ? ... not true.. as proven with dynamometer tests.
You might foul plugs a little more often.. but the motor will like the oil.
I hope this guy wasn't running NO oil in the gas !?!?!
