> The problem with alcohol is that it absorbs moisture really well. The pure
st you can buy at the drug store is 91%, because it isn't economical to get t
he rest of the moisture out. After it sits in your tank, even in Arizona, fo
r a few days it is likely to be down to 70% or less. At those ratios it can s
tart corroding your aluminum. I don't know that proseal is all that alcohol r
esistant. Mooney puts a sealer over the proseal to protect it but you RV tan
ks are just straight proseal. Older versions of proseal would soften up a lo
t when exposed to mogas. I think the current stuff is okay with mogas, but s
till wouldn't use 91 or 93 pump gas unless it would be consumed in a single f
light, within a few days, whether it had alcohol or not.
