Gods of fiberglass and steel

I have the original aluminum fuel tank in our 25XF which last year the surveyor said looked great. It is a 1982. Does this E-10 which we have to run at times really cause electrolysis in aluminum tanks? I do put in gas stabilizer. It is a 120 G. tank We run her at 1/4-1/2 because of the weight. Any thoughts? Thanks Gary

Electrolysis isn't the bugaboo with E10. Problem is that it acts as a cleaner/solvent and will put into suspension any crud & varnish that has accumulated in the tank and fuel lines over the years.  Good policy is to replace your fuel lines with alcohol rated lines and do frequent fuel filter changes to keep the loose debris out of the carbs.  Carry spare filters in your kit too.
