I too am in the fillup every 6-8weeks. I can do 2-3 mods per fillup so I don't know which is improving the most. I've researched (from the racing community) fuel tank spacers. They are made to fit in the fuel tank to lower it's overall capacity. They are expensive and the 1/2 gallon size would not fit into my tank. So I'm trying to find common material that I could put in the tank that would lower the capacity of the tank. Tried (white plastic) pint milk cartons. They work in the gas/ethenol blend but the little wax seal on the lid dissolves and the cap comes off and they are not effective anymore.
I'm experimenting with 3 inch plastic balls now (the kind you would see in the play area of the pizza parlor). They are in a glass container filled with gas on my back poarch. I want to make sure they don't dissolve before I put them in the tank.
I dislike carring around 36lbs of fuel for a month while I'm using the first 36lbs of fuel in the tank.
