|jrcnova||My Speedo has not been recalibrated,hence my question.|

I just don't know why it's so difficult to measure fuel mileage?
Step 1: Use a GPS to verify your speedometer/odometer readings.
Step 2: Fill up with gas. Note odometer reading.
Step 3: Drive vehicle normally until it needs gas again.
Step 4: Refill with gas, noting how many gallons it takes to fill up.
Step 5: Divide gallons of gas used into miles driven.
Step 6: Wonder if driving your Jeep is worth the cost of fuel to operate it.
Step 7: Go on Jeep forums and either Brag about your mileage ( anything over 16 is bragging ) or bemoan how poor your mileage is ( under 15 )

|Jerry Bransford||If the speedometer is reasonably accurate or has been recalibrated after changing the tire diameter, the mileage shown on the odometer is accurate enough for 99.999% of us wanting to know our mpg.|

|Jerry Bransford||That's a lot of math to arrive at the same answer given by simply dividing the number of miles driven since the last fill-up by the number of gallons required to refill the tank which provides the mpg.|

New to the forum and to Jeeps. Just bought a 2000 TJ 4.0, 5 speed with a 4" lift and 35x12.50/15. I scoured the forums to figure out how I can determine my gas mileage. Correct me if I'm wrong but the following equation is what I've found.
Current tire diameter / original tire diameter = answer
Answer X odometer mileage = actual mileage driven
Actual miles driven / number of gallons purchased = mpg
So with that said here's what I've come up with:
1.263537906 X 165.5 = 209.11
209.11/11.392 = 18.36 mpg
