How to check your BMW 328i’s gas tank size

Besides remembering all those details or figuring out the location of your owner’s manual, you have options when it comes to finding out the gas tank size. 

Measure the gas tank

Option #1 is to break out those basic math skills, a measuring tape, and a calculator. Measure the gas tank’s length, width, and height, then multiply all three numbers. Divide this new number by 231 (how many cubic inches are in a gallon). The final result equals the number of gallons your gas tank uses.

Check your owner’s manual

Option #2 means finding your owner’s manual. Look up “fuel tank capacity” or similar phrasing and see what number the book lists. 

Drive till empty, then fill it up

Option #3 supposes you don't have an owner's manual and don't want to measure the tank yourself, but you're up for trying something a bit risky. In that case, you can figure out your 328i’s gas tank size by driving until your fuel gauge hits “E” before you fill it up
However many gallons it takes to fuel the cay will give you the general idea of the tank size. You won't get an exact result, but this option gives you a decent estimate—just don't drive too long on empty (and have a cell phone on hand).

How to save on fuel costs in a BMW 328i

With a gasoline engine, the BMW 328i is rated for about 18 mpg in the city and up to 35 mpg on the highway, though most makes fall below the 35 mpg mark. 
Regardless of how good your mpg is, you don't want to spend your next paycheck fueling your 328i. So if you want to save gas and money at the same time, try these tips: 
  • Maintenance. Wear and tear on your 328i system means your fuel economy will go down. Help your car run longer and save on gas money by prioritizing maintenance.
  • Drive carefully. Don’t mash the gas pedal every time you accelerate; it lowers your fuel consumption. Easy does it!
  • Avoid idling, even when it’s cold. Idling burns through your fuel with minimal benefits, so skip letting your vehicle run while in park and instead drive your car to warm it up on those cold winter mornings.
