When you roll up to the pump, it’s crucial that you know your gas tank size. You can find this information in your owner’s manual, but if you’ve lost the manual or bought the car used without the manual included, you’ll need to find this information elsewhere.

How big is the gas tank on a 2005 Ford Excursion?

As the longest and heaviest SUV to ever hit the market, the Ford Excursion has a giant gas tank that retains its size across trim levels and configurations.

This model comes with a 44-gallon tank and a 5.4-L Triton V8 engine. This size is needed due to its poor mileage of 13 mpg city and 17 mpg highway.

How to check your 2005 Ford Excursion’s gas tank size

If you don’t believe the gas tank on a 2005 Ford Excursion is really that big, you can use a few approaches to confirm our findings and drive with confidence.

Measure the gas tank

First, you can measure the volume of the gas tank on your own. Grab a measuring tape and a calculator, then measure the width, length, and height of the gas tank. Take these figures and multiply them together. Then take the sum and divide by 231—the number of cubic inches in a gallon.

Check your owner’s manual

If you can get your hands on an owner’s manual, you’ll find the gas tank size in there. Look for a phrase like “fuel tank capacity” or similar terms to find the correct info.

Drive till empty, then fill it up

If you like living on the edge, you can always drive until the fuel gauge hits “E” and then fill it up. This won’t give you an exact measurement, but it will give you the general tank size. Just be sure you don’t run out of gas and end up stranded!

How to save on fuel costs in a Ford Excursion

The 2005 Ford Excursion gets horrible gas mileage at 13 mpg city and 17 mpg highway. This gives the vehicle 15 mpg combined, which is pretty poor—although not bad when you consider the size and weight of the vehicle.

Still, with a vehicle this poor on mileage and a gas tank of this size, you’ll want to save on fuel costs. Try these tips to cut back on your gas bill:

Maintain your vehicle regularly. If you let wear and tear carry on for too long, it’ll start to affect your fuel economy.

Drive safely. Don’t accelerate quickly and drive a little slower to save on gas.

Don’t let your engine idle, especially in cold weather. On a cold day, it might be tempting to let your engine run to get the car nice and warm, but this will waste your gas and lower your fuel economy.
