Hello and welcome to Fuelly. 15 MPG, assuming you mean amazing in a sarcastic way??

I'm assuming when the OP says "Square Body, they're referring to a 73-87 full size GM pickup truck. I used to average 25 in my old 74 (no emissions equipment), but my 86 which was laden down with emissions equipment could barely do 18 on the highway.

15 MPG not bad for a '79 K20
