How big is the fuel tank on my car?

The question “How big is my petrol tank?” is one that most vehicle keepers in the UK must have asked themselves since they purchased their vehicles. There are several methods to identify the fuel capacity of a car. You could:
  • Check the owner’s manual
  • Generate a car history report with SmartCarCheck
  • Empty your tank and fill it up
  • Measure the tank yourself

Check the owner’s manual

The owner’s manual is one very important document that you can use to get basic information about a vehicle. With the owner’s manual, car keepers can easily gain information about vehicle parts. In this document, you should be able to easily get the answer to your question and find your vehicle’s fuel tank capacity.

To do this, simply get the owner’s manual of your vehicle and flip through the pages until you find the vehicle specifications section. In this section of the manual, you can be sure to find out just how much fuel your vehicle can hold in gallons or liters. According to Wikipedia, the average fuel tank capacity of a vehicle is between 50 and 60 liters (12 and 16 US gallons).

If you can’t find the fuel tank capacity of your vehicle in the manual, or perhaps you can’t find the owner’s manual, you have nothing to worry about as there are other easy methods you can use to get the size of your fuel tank.

Generate a car history report with SmartCarCheck

To check the fuel capacity of a vehicle with the vehicle inquiry service provided by SmartCarCheck, simply visit the website, provide your registration number or license plate number, and search. After the check, take a good look at the section titled “Weight and Dimensions.” Here, keep an eye out for fuel capacity, and you’ll find out just how much fuel your fuel tank can hold.

This step is particularly important for car buyers at dealerships, especially if they are interested in driving for hours daily. With a registration number check, you can easily find out your vehicle’s fuel tank capacity and also gain access to other vehicle information that would help you make the best decisions and purchase the right vehicle for your needs.

Empty your tank and fill it up

This is a very risky step to take, but it is an essential part of determining your vehicle’s fuel tank capacity. So here’s what you’ll do: First, you have to make sure that your tank is completely empty. Yes, you have to run your tank below E to get accurate results. It’s risky, as you could get stranded on the way to the gas station, but it’s one way to get to know your fuel tank capacity. To avoid being stranded, you could get a fuel can on hand just in case. When filling up your tank at the gas station, be sure to pay attention to the quantity of fuel that goes into the tank. By the time your tank is full, you will have an accurate value for your fuel tank’s capacity.

Measure the tank yourself

The last method to follow to determine your fuel tank’s capacity is to actually measure the length, width, and height of the tank. After measurement, you can determine the fuel capacity by calculating its volume. All you would need is a meter rule and a calculator. Start by writing down the measured values and using the following formula:

Volume = Length x Width x Height

For example, if your tank measures 50 cm by 30 cm by 40 cm, the volume would be:

Volume = 50 x 30 x 40 = 60,000 cubic centimeters

To convert cubic centimeters to liters, divide the volume by 1,000:

Liters = Cubic Centimeters ÷ 1,000

Using the example above, the tank would have a capacity of:

Liters = 60,000 ÷ 1,000 = 60 liters

If you prefer to use gallons, you can convert liters to gallons by dividing the number of liters by 3.785:

Gallons = Liters ÷ 3.785

Using the example above, the tank would have a capacity of:

Gallons = 60 ÷ 3.785 = 15.85 gallons

The fuel capacity of a vehicle is an easy-to-get detail as long as you follow either of the methods mentioned above. For car buyers in the UK looking for how to check their vehicle’s fuel tank capacity, make sure to use the vehicle inquiry system provided by SmartCarCheck, as the car history report would also contain some information that you can use to verify the overall condition of a vehicle.
