Poor Gas Mileage

When you put in the 14.5 gals how far did you travel? That's what we've been waiting for. Here's the process once again:

Fill your tank.

Reset trip odometer to zero.

Drive it until it's near empty.

Fill your tank again.

Write down the number of gallons you filled it with.

Write down the number of miles on the trip odometer.

Divide the number of miles on trip odometer by the number of gallons you used.

Report back the results.

You should know that the first half of the gauge goes quickly in Mustangs. Usually when my gauge hits the half way mark I have gone 100-120 miles. By the time it hits E, I usually go about 250-270 miles. As you can see, the gauge is not linear. When I first bought my Mustang and saw that gauge move so fast I couldn't believe what I got myself into. Then I realized that the needle started moving slower toward the bottom. I figured about 40 miles a notch. The top half is like 25-30 miles per notch.

And you may notice that the needle sits on full for a while and then when you shut down or drive a while, boom, it's plummeted.
