Hey Guys,

I have a couple of LS trucks in the house,
Wifes 2007 Denali 6.0 AWD 105K

and my 2007 Silverado LTZ 5.3 4wd

Just got my Silverado and it is debaged - how do i tell if it is a flex fuel motor??

thanks

itll say flex fuel, and your gas cap will be yellow, or green or some crap other than black
