I'm having trouble putting together a truly factual reasoning on this, but I 
wouldn't do it nor advise it.

I'd be nervous going that full - isn't there a chance of some (or a lot)
getting through an open exhaust valve and damaging oxygen sensors, cats,
etc.?  That's if it gets up past the rings.  Which would also create a
nasty hydrolocking issue too... or is that unlikely to happen?
