2Much,

Make sure you vent that fuel tank/catch can arangement.

Kweasel,

What part of the rod fails on a two stroke before piston siezure? The small end at the wrist pin?

I guess a brave heart could blend the oil content down by mixing the correct ratio of mehtanol and nitro into their current 4 stroke fuel and give it a whirl.

RedB's point is still valid. Nobody really seems to know for sure.
