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. > > > >> On Sun, Sep 19, 2021 at 10:19 AM Doc wrote: >> >> Other than deteriorating the mechanical fuel pump parts and perhaps the >> fuel sensor, (I assume the tank factory sealer is alcohol proof) is >> there any reason why E-10 could not be burned in the parallel 540 with >> 8.5 : 1 as all the plumbing is aluminum tubing?
