In the whole history of any forum, ever, has there been an agreement between whose right?
Stabilizer OR Not
Ethanol bad OR Not
Ethanol more prone to separate OR Not
Tank full OR Not
Tank EMPTY OR Not
Ad nauseum
No, because there is no one right answer. Else there wouldnt be hundreds and hundreds of these questions posted every year in numerous forums, iboats included.
Maybe a fuel sticky should be posted every early fall listing all the numerous gas and winterization topics.....
In a garage, heated or not, I wouldnt be overly concerned w gas in the tank if you have a separator on the motors fuel line and burn numerous tankfulls over the season. If you think adding Stabilizer helps, great, it isnt particularly expensive against the cost of a tankful of gas.
