Thread: E85 Flex Fuel

  1. #1

    Default E85 Flex Fuel

    Is there a way for me to tell, from the VIN of some other source, whether or not my 2005 Chevrolet Silverado will safely burn E85. I've got the 5.3L motor. Thanks alot!

    There is a VIN decoder here on the site, and or else call the dealer but if you dont have E85 stickers then it is unlikely.

    Welcome aboard. The easiest way to tell is if your gas cap is yellow. The other way to tell is from the RPO code which you can get on the inside of your glove box.

    Mike: compnine.com is the site, but the decoder doesn't appear to be up. They do have a list of RPO codes, which is where I found it.

    As said above your gas cap should be yellow and it should have E85 on it.
