E85 safe on fuel system?

[StickShiftyFifty]

I did a search with no luck, maybe someone can answer my question. Ive been running e85 since i boosted the car. I know that e85 is real corrosive on rubber components. Is it safe to run it all the time? Is there anything long term i should be worried about?

I wouldn’t worry about it unless your fuel sits in there for say over a year. Then you might get some water in it. Always makes sure your fuel cap is shut since it will absorb water. Think about it, every car on the road runs 10% ethanol for what 25 years now whenever E10 became the norm. If it corrodes things that bad we’d have heard about it by now
