flex fuel and shelf life ?

[d.mehrl]

Storing the truck this winter, 3 months or so. Can i fill it with e85 flex fuel, or does e85 go bad sooner than regular fuel ? Thanks in advance !

From what I understand if it is sealed, it will last for years. If opened to the atmosphere, it will suck moisture out of the air and get a little bit diluted.

Hello. The shelf life of E-85 is 90 days. I used E-85 all summer in my last two GMC trucks. The trucks were stored all fall until I use them in the winter. For me that's four months. No issues with the fuel. Randy

can you use fuel stabilizer in it like you do in regular fuel?

if your storing it for a long period of time, i thought it was better to park it with pretty much an empty tank....

I think my yellow gas cap says, No fuel additives". I think thats for flex fuel only. I'm sure you can use stabil in regular gas..........

only if your tank is plastic. if its a steel tank you want it filled up other wise itll start to rust on the inside

It says do not use additives with e85 on the inside of my fuel door

Most fuel additives are fuel system cleaners, which is alcohol-based to remove gunk and varnish left behind by gasoline. Since e85 is mostly alcohol, it don't make sense to add a bottle of that pricey crap. E85 makes your engine self-cleaning!
