My question is about the effectiveness of stabilizer over a long
period of time.

My boat is normally stored from oct-nov to june-july. At the moment,
I have about 40 litres of 2 month old gazoline in the 100 litre tank.
Should I try to drain it and refill with stabilizer added to the gaz ?
Or should I just add fuel to fill the tank and assume that adding
stabilizer will properly treat all of the fuel for 8 months? The motor
is a 90hp Mercury 4-stroke.

Where are you located?

The gas that we get here in New England after 2 months of sitting in the
tank is old and has "deteriorated." SAure, it burns, but it's not as good
as fresh gas. Adding stabilizer to 2-month old gas may not do any good.
The instructions on the stabilizer bottle say that it is best to add it to
fresh gas.

It's best if you can drain the 2-month old gas that you have in your boat
tank (and burn it in your car or other gasoline engine). Then add some
fresh gas and stabilzer to your boat tank and run the engine 10 mins to get
the treated gas into the carb/fuel injection system/whatever.

They used to say that it was best to fill the boat's gas tank to the top
before the winter so as to avoid having moisture condense in the tank.
However, two very good marine mechanics each told me last fall to leave the
level low for the winter after adding stabilizer to the fresh gas. Then in
the spring, fill up the tank with fresh gas.
