Hi all, I have a 2003 Flex Fuel engine, and since buying this truck used in 2014 I have NEVER put Flex Fuel into it.
I was wondering if using that fuel could be an issue after so long of never having used those components before.
Since I'm sure the computer has to kick into some certain mode for it, right? Could certain essential parts be worn out after decades of non use?
Anyways, just wondering if there was something to look out for, haven't done it yet, and wanted to ask the community before trying it.

Thanks for any input!

 

Your trunk is Flexible when it comes to fuel...Use what ever you want, wont hurt anything.

 

Thanks for the input! I have no idea how flex fuel engines work lol. Oh and hey nice wheels, I have the same!
