I don't think anyone is in disagreement that over-filling is to be avoided.

I think the question is, is it more risky/hassle to drain some oil out (possibly damaging the drain seal) or to just leave it and risk future engine problems.

Without a real dipstick, we have no way of knowing exactly how much over the level is, but my view is that if the difference between full and overfill was that critical then this would be recorded by the ECU and the warrantee would be voided. Maybe a little extreme and a little tongue in cheek, but you see what I mean. I figure there is a safety margin, and the manual is always going to say "Don't ever overfill", as it's not going to say "If you overfill, don't worry about it"

As MMD hinted at earlier, some people take the manual as gospel, some people use more flexible judgement.

The fact that OPCs can overfill on our behalf stinks though.
I have trouble enough getting them to understand that when I say "Don't wash the car" I MEAN "DON'T WASH THE F'ING CAR! - When all the cars in your showroom have swirl marks on them, what makes me think you can wash a car properly?"
