I saw discussion here a while back about possibly running Mobil 1 0W40 European. I was curious if anyone here had done this and gotten an oil analysis? If so, were wear numbers significantly lower? Also, what is the mileage penalty?

I have been considering changing to this and know it won't harm the engine but figure there is no point if it provides no additional protection (improved wear metal counts) as there will be a mileage penalty.
