Too much oil can also burn up an engine. The extra oil displaces
fuel, which leans the air/fuel mix causing heat. Also, 2-stroke oil
burns hot anyways, so the extra oil makes it worse.


- these folks say
it is the oil that determines the mix- not the machine. . and
theirs is 100-1


The oil manufacturer determines how lean it can be mixed and still
properly lubricate an engine. The engine manufacturer decides the
proper mix for the engine. Drastically changing the oil mix (from
32:1 to 100:1 for example) requires recalibrating the carb. Those
people probably make a good oil, but it still gets mixed 40:1 if it
goes in my chainsaw.
