Just discovered

I just found out after a year of owning my Tahoe that it’s a flex fuel anything I need to look out for that’s special to the flex vehicles?

just the ancillary fuel filter on the driver-side of the frame that needs to be occasionally replaced just like any other serviceable component.

if you can't find the schedule for it, I can dig something up.
