New fuel economy for my truck is...

15.25 MPG on 91 unleaded fuel.

it was of time and the computer was throwing weird codes <img src="/forums/images/graemlins/zombie.gif" alt="" /> its still not awesome but it might also have something to do with Venezuelan gas quality. Way less regulations here <img src="/forums/images/graemlins/barf.gif" alt="" />.

1, miles traveled per tank= 172.74
2, gallons used= 11.3
3, engine size= 3.0 12V
4, tire size= 31"
5, year and model= 1997 Montero GL Dakar SWB
6, other mods that may affect fuel economy= I'm pretty sure it has a smaller muffler than it should.
