Audi may have cut down its gas tank sizes over the years, but that doesn’t mean you’re being ripped off! Along with gas tank capacity, you also have to think about fuel economy, or how many miles a vehicle can be driven before one gallon of gas is consumed.
That is to say, while the 2023 Audi A4 only holds 15.3 gallons, it has a fuel economy of 28 mpg—which is 10 miles more than the 18.5-gallon 2003 Audi A4!

Maybe you’d like to double-check—no worries, we get it. That’s why we’ve got a few more ways for you to figure out your Audi A4’s gas tank size.
Measure the gas tank
Pull out your measuring tape and a calculator. Find your gas tank and measure the length, width, and height in inches. Multiply those numbers, then divide by 231 (the number of cubic inches in a gallon).
If you have a newer Audi, the result should be 15.3 gallons, more or less!
Check your owner’s manual
Rummage through your glove compartment and grab your owner’s manual (that you hopefully still have). Scan the table of contents and look for the term fuel tank capacity or gas tank capacity to find your magic number.
Drive till empty, then fill it up
Finally, the most precarious but accurate way of figuring out your gas tank size is to drive until your fuel gauge reads empty, then visit the nearest gas station. Fill up your tank and look at the total gallons you’ve pumped in. That’s the approximate capacity of your tank.
