E85 capable?
 

I have an '04 5.3 truck. It's not marked as being able to run E85 but did see a couple of trucks that say it on the emissions tag under the hood. My doesn't. Is there a way to see if I can run E85?

I used E85vehicles.com before for my '00 S-10 to lookup my VIN, which told me - but I didn't see it there when I looked - but I found this at E85answers.com:
