I was just thinking about this the other day during the 47 threads on T/GDI fuel dilution of the engine oil. It seems to be, at least to some extent, that these engines should never suffer being sludged to death, right? I mean, if they are truly dumping 3, 5, 9% volume of gasoline into the engine oil, and gasoline is obviously a solvent, is it even possible for an engine to form sludge with that much solvent in it?
Obviously there are the other concerns of fuel in the oil causing lubrication problems, which, at least to me, seem to be mostly unfounded since we are not having engines fail left and right after they've put up a 3-5% fuel content on their UOA. So I'm lead to believe that a majority of the fearmongering of fuel in engine oil is just that, and with today's oils and add packs, a low-level fuel intrusion does not have a negative effect on lubrication, and may also keep engine oil from sludging? Just a thought...
