Isobutanol gas and fiberglass tanks

[Jerrytex]

Just wondering if anyone has any info on whether or not the old fiberglass tanks will handle the new 12% Isobutanol being mixed in with gas. Apparently this is most likely going to be the replacement (still alcohol) for Ethanol. Where I live, for the longest time we have no E0 available. Now there are stations popping up with E0 but they contain 12% Isobutanol. The little bit of research I have done shows that it might actually be a good thing because it eliminates the issues with water, phase separation and corrosion issues. But....I can't find anything on what effects it has on fiberglass resins.

I've got my old tanks from the Mangy that I will give to anyone wanting to do any fuel testing. You just pay the shipping.

Jerry,

Empirical Information on isobutanol and fiberglass aircraft fuel tanks is pretty sparse.

One thing you could do is google up the topic on boat fuel tanks - that interest group is fairly large and there is some info on the subject.

I tried it, never again, go look up a thread about the saga!
