If one fuel is already in your tank and you add the other to that tank, there should be no issue, so long as you are meeting minimum octane requirements for your engine. If the fuel in the tank has sat for any major length of time without stabilization, that could potentially be problematic
If I had left over gas from an outboard tank at the end of the year, I'd dump it in my automobile as the fuel will be quite diluted given the fuel tank on the auto is larger.
