I doubt 3oz more is going to hurt any vehicle
You do what you think is best. As for me, I'll trust the people that designed the engine. Here’s a direct quote from the Honda Operator Manual for the GX200 engine:
You may use regular unleaded gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume. In addition, methanol must
contain cosolvents and corrosion inhibitors. Use of fuels with content
of ethanol or methanol greater than shown above may cause starting
and/or performance problems. It may also damage metal, rubber, and
plastic parts of the fuel system. Engine damage or performance
problems that result from using a fuel with percentages of ethanol or
methanol greater than shown above are not covered by warranty.
