if i was to buy an 89
5.0 gt
automatic
rebuilt engine with 28k on it
everything is pretty much stock
what should my gas mileage be around?

 

My 88 5.0L gets around 21-24 mpg completely stock

 

Ofcourse results are going to vary depending on how heavy your right foot is

 

i have a 92 lx w/ 5spd and a few mods. i have a hard time keeping my foot out of it. but when i drive somewhat normal getting into it once in a while. i get right around 18-20. and my car runs a little rich from my tuneup

 

average spd on the interstate around 80 I'm getting 22 MPG ... I like my car...

If I could stand to go 55-60 i'd be getting 25
