Not sure if this has been posted : http://www.motortrend.com/news/your-next-car-might-change-its-own-oil-technologue/ : Not enough info to really evaluate this system. Initial impression : Seems incredibly bulky, expensive, weight distribution seems wrong. I'm sure theirs more to it then what's listed in the article. Got me thinking though. How about just getting rid of the "archaic" task of having to get under the vehicle for service. It Wouldn't be that expensive to engineer a way to change the oil & filter from the engine bay.
