How large is the gas tank on a 2023 BMW X3?

This is a BMW that stays true to its roots of a driver-centric, invigorating behind-the-wheel experience. There are three trim levels and two engine choices for 2023: 
  • 2.0-liter inline-four cylinder with 248 horsepower
  • 3.0-liter inline-six cylinder mild hybrid with 383 horsepower
But no matter which potent engine you choose, the gas tank size is 17.2 gallons

Getting to know your 2023 BMW X3’s gas tank size

If you’d like to hear it from more than one source, you’ve got options. Here are a few other methods that you can use to determine your X3’s fuel tank size:

Measure that gas tank

If you’d like to get up close and personal with your new X3, you can measure the gas tank at home. Get a calculator and a measuring tape and measure the length, width, and height of the gas tank in inches. Multiply those together and divide that number by 231. The end result is the capacity of your gas tank in gallons.

Peruse your owner’s manual

Your beautiful new Bimmer should have come with an owner’s manual full of useful information. Look for a section called “specifications” or “capacities” to find your gas tank’s capacity straight from the horse’s mouth. 

Take the highway to the danger zone

Not literally, though. If you don’t mind a little risk (or embarrassment), then you can determine your gas tank’s capacity the hands-on way—drive it until it’s as empty as you can stand, and then fill it up to approximate its maximum capacity

How to save on fuel costs in a BMW X3

Considering what powerful engines the X3 has, the gas mileage isn’t bad at all. Depending on which version you choose, you can expect to get anywhere from 23 to 25 mpg in combined city/highway driving. 
You’re going to want to spend some time cruising around and bonding with your trusty new car, so here are a few tips to get the best mileage possible—both now and down the road. 
  • Keep up with maintenance. Being diligent about routine maintenance will not only keep your BMW at its best, but will also ensure that you get the best gas mileage possible.  
  • Drive carefully. We know this is going to be hard with all that horsepower at your disposal, but keeping rapid acceleration down will prop up your fuel economy.
  • Avoid idling. Sometimes it can’t be helped, but idling is a huge waste of gas. Keep it to a minimum as best as you can!

This app is great, but the customer service is even better! Not to mention convenient! My husband and I got the lowest rate (much lower than the rates I was finding online through my own searches), quickly, and pretty much all through text message! Thank you so much for a hassle free experience👍
