# How Many Gallons is a Full Tank of Gas? Average Car Gas Tank Size

I recall going grocery shopping with my father for the first time. He bought a gallon of milk and filled the rest of the cart with gallons of gas. I remember thinking how wasteful he was and was surprised when he said, “A gallon of gas is just bigger than a gallon of milk.” I’ve been working with car insurance companies for the past decade.

My favorite question to ask customers is to estimate how many gallons are in a full gas tank. Unfortunately, about 50% of people can’t answer this question correctly.

When you go to the pump, do you ever wonder how many gallons of gasoline your car can hold? Of course, the size of a car’s gas tank varies, but a tank can save between 14 and 16 gallons of gas on average. Check out our post to learn more about the average gas tank size and how many gallons you need to fill up your car!

## How much gas does the average car hold?

You’re not alone if you’ve ever wondered how much gas is in your car’s tank or you’ve been unsure of how much gas to put in. Many people aren’t sure how much gas their car holds, even though it should be straightforward. But, different car models have different gas tank sizes, so it’s not as simple as you might think. For example, the BMW 6-series has a 17.7-gallon tank, and the BMW 3-series has a 14.8-gallon tank. These differences in gas tank sizes make it difficult for drivers to know what to expect from their car.

The average car gas tank size is about 15-18 gallons. So the average car can go about 400-500 miles on a single tank. Of course, this varies depending on the type of car and how heavy your foot is on the pedal. But in general, that’s how much gas you’ll get out of a full tank.

## What does it cost to fill a gas tank?

If you’ve never filled up a car with gas before, the first time you do it can be scary. You’re probably worried about overfilling the tank, or worse, underfilling it. But don’t worry. Filling up your car is pretty easy. Once you know how much gas is in a tank, you can calculate how much gas you need to fill up your tank. Individuals could then enter up your tank without worrying about paying for just any additional gas.

A comprehensive gallon of gas in most cars today holds 12-16 gallons and costs between \$25 and \$40. So yeah, of course, it’s difficult to predict how much it will cost to fill up your tank with the ever-changing gas prices. But, as a general ballpark figure, it will cost between \$2-\$3 per gallon to fill up most tanks.

## How often should you fill up your gas tank?

You should check your owner’s manual to find out the recommended fuel level for your car. Once you know that, you can start watching the fuel gauge and plan your fill-ups accordingly. Try to aim to refill your tank when it’s around a quarter or half full. This will help you avoid making emergency stops at the gas station, and you’ll save money on gas in the long run!

## What are the benefits of having a full tank of gas?

Having a full tank of gas provides you with several benefits. Gasoline is one of the most valuable commodities on the planet and can be used for virtually anything. It serves as a heating device and cooking fuel in many countries. If you have a full tank of gas, you’re prepared to handle any emergency that comes your way.

If you’re ever stranded, you’ll have enough fuel to get you to a safe location. You also have a greater chance of being rescued if you’re in an emergency. While it’s true that most gas stations can pump gas at the same rate, If you are in a hurry, you may find yourself waiting in line for an extended time. Having a full tank of gas allows you to avoid this situation altogether.

Having a full tank of gas is beneficial in a few ways. First, you won’t have to worry about running out of gas in the middle of nowhere. This even guarantees that someone’s motor is operating at peak efficiency, which saves you money on gas in the long run. Ultimately, it provides you with peace and allows you to travel easily.
