Measure the gas tank

Have a measuring tape and calculator ready to calculate the fuel tank capacity manually. Measure and multiply the width, length, and height of the tank in inches. Once you have the answer, convert it into gallons by dividing it by 231

Drive till empty, then fill it up

Then you’ll need to fill up the gas tank. This method will give you a good estimate of how big the Toyota RAV4 gas tank is. Just remember to start driving towards the gas station before you hit “E” so you don’t run out of gas.
