Rod .... not according to the chart in the link I posted !! Different ingredients & different % of them are listed.
They all do seem to contain one or more of three basic ingredients ... solvents, petroleum distillates, alcohol. Their whole point is that E10 gas already has solvents & alcohol, so adding to them may not be a good idea. Those products containing mostly petroleum distillates are not water absorbing, so they don't contribute to the problem.
Stoddard solvents are listed as the ingredients of several products ... and it's one of the main ingredients in WD-40 (which is primarily a water dispersing solvent).
For those that use & replace the gas in their tanks, or keep the tanks full on a constant basis ... additives may not be necessary. If the gas is allowed to, or by necessity has to sit for more than a couple of months, then a stabilizer may help. Filling your gas tanks to the max, prior to them sitting for extended periods, can also help ... as it lessens the evaporation/condensation exchange. A water seperation filter system, added to your boat, may be the cheapest way to go in the long run. IMHO (& I will probably be putting one on, in the very near future)
