According to the boat-maintenance book, I am supposed to fill the fuel
tank to the max and treat the fuel with fuel stablizer, and running the
motor for 15 minutes to get the treated fuel into various parts of the
motor. And this is exactly how I winterize my lawn equipments. But
the salesman of the boat dealer asked me to run the motor until the
fuel tank is dry and then fog the motor (I guess this means spraying
the inside of the engine with a can of fogging oil). His explanation
is that the quality of the fuel in the market is getting worse and
worse, and the old way of winterizing the fuel system doesn't work well
any more. This is new to me. I don't know much about marine motor.
Therefore, I need your help to give me the right info. In any case, I
really don't like the idea of running all 44-gallon of fuel dry because
I am not ready to bring the boat for outing yet (not ready until next
year).

I live in northern New Jersey if this matters.

Thanks in advance for any information about this issue.
