Questionable as to whether it will actually harm anything with the exception of fuel economy, but doubtful that there are any benefits. Even though an engine may have been originally designed many yrs back - engineers do make changes geared to improve mpgs in areas like oil pump size and capabilities, reduced oil feed passages and bearing passages, and you also have relatively small bore sizes for stuff like the CVVT cams.
I'd feel comfortable with a 5w-40 but can't see any good reason to go to a higher weight.
