Gas mileage gone bad.

How do you know you used two gallons? Just by the fuel gauge? The fuel gauge is a best guess. Although, if you noticed the needle moved that much (about 2X) when it usually doesn't, could be something there.

Keep driving it until 1/2 to 1/4 tank, then refill and calculate the fuel consumption by hand?

Correct! thats what I do its more accurate if the gas gauge needle is below the center.

@ ProjectM96... Hot climate can affect miles per gallon also try cleaning the fuel system..

The only way to be sure is to divide miles driven by actual gallons used. Our gauges are flaky (to be polite).

Everytime I fill up the tank, I reset the mileage counter so I know how many miles I drive on a tank of gas.

It looked like the needle on the gas gauge was going down much faster than usual. So I went back to the gas station the next day and refilled it to see how much gas I really used in that 18 miles. It filled up with 2 gallons of fuel.

You will not get an accurate measurement after only 18 miles. Like I said before, drive until you're at less than 1/2 tank. Better, less than 1/4 tank. Then refill and calculate. Fill up from the exact same pump you used on the last fill-up.
