I think it's fine to use. If you don't have any leaks, there may not be much to gain from it. The Honda J35 engine seems to love light oils, and high mileage oils are often on the heavier side of the scale for any given grade, and sometimes have constituents that are not optimal for fuel economy.
If you don't have any oil leaks or oil consumption issues, I probably would stick to oils other than high mileage oils.
