4.11's brought my mileage back to 16 mpg?

I have 33's and swapped from 3.07 to 4.11 and I only had one test run and it seems as though my mileage was brought back up from 12 ish to about 16.. How accurate could this be? Thanks for any input and please don't think I don't know it's a jeep I will still be driving it no matter how bad the mileage is

I had stock 3.27s? I put on 35's and ran for about a year without doing gears and gas milage sucked! transmission was always trying to find gears well I upgraded to 4.88s and my gas milage had to go up cause I can make it about 2 weeks instead of 1 1/2! I think it makes a difference I need to do the math though!
