What’s the size of the gas tank on a 2013 Infiniti G37?

No matter how it's configured, a 2013 Infiniti G37 has a 20-gallon gas tank.

The luxurious Infiniti G37 is available in a coupe, sedan, or convertible body style for the 2013 model year. When purchasing brand new, buyers also had the choice of rear-wheel or all-wheel drive and a manual or automatic transmission. The sole engine option is a 3.7-liter V6.

Determining your 2013 Infiniti G37’s gas tank size

If you’re the thorough type and want to double-check this spec, there are a few ways that you can go about it.

Calculate your tank’s capacity

This will involve some math, so grab a calculator. Take a measuring tape and measure the height, width, and length of your gas tank.

Multiply those numbers together to get your tank’s volume in cubic inches. Then, divide that number by 231—the number of cubic inches in a gallon.

The end result? Your gas tank capacity in gallons.

Find it in the owner’s manual

Even if you don’t have the manual anymore, you can often find a copy online! Look for a chapter or section about “specifications” or “capacities,” and you should be able to find the size of your gas tank there.

Drive until it’s empty, then fill it up

If you want to take a more immersive approach, you can just drive until your tank reads empty, then see how much gas it takes to fill it up. Just use caution and don’t press your luck too far—you don’t want to end up stranded.

How to save on fuel costs in an Infiniti G37

It may be posh, but the Infiniti G37 is not exactly what you’d call economical when it comes to gas. Its thirsty V6 engine will get anywhere from 19 to 22 mpg combined, depending on its powertrain and body type.

Maximizing your fuel economy in this luxurious beast is important, so here are a few tips to help you get the most bang for your gasoline buck. (Not literally though. No explosions.)

Be diligent about maintenance. A car that is well maintained will not only run better, but it will also have the best fuel economy possible. Keeping your tires inflated to the proper PSI helps with fuel economy as well.

Drive carefully. Avoiding rapid acceleration will keep your fuel consumption as steady and as low as possible.

Keep the idling to a minimum. Idling is a big waste of gas, so try not to let your engine idle for too long at any given time.
