How long can e85 sit in tank ?
 

Hello guys.

I am running e85 and I will go to vacation 2 months.
So is it fine to let e85 sit in tank 2 months or should I switch to gasoline ?

Thank you.

If you can switch do so. Better safe then sorry.

Per Google:

Gasoline Expiration - Ethanol Blend Fuels Have a Short Shelf Life. An Alcohol Fuel Test Kit will give you the data you need to keep engines safe with E10 gasoline. E10 Gas has a shelf life of only 3 months. Ethanol alcohol fuel blends have a shelf life of only 90-100 days, under ideal environmental conditions.
