Official specifications and what they mean
For most U.S.-market RX 350 models, the manufacturer’s specifications list a fuel tank capacity of 17.1 gallons. This figure is the practical standard you'll see cited in dealer literature and owner manuals, and it informs daily fueling planning and range estimates.
Notes on variations by year and market

If you need the exact figure for your specific vehicle, check the owner’s manual, the fuel-filler door label, or the vehicle identification label in the trunk or door jamb.
Practical implications for drivers
Understanding the tank size helps with estimating driving range and planning refueling stops. To estimate how far you can go on a full tank, multiply the tank capacity by your vehicle’s average miles per gallon; real-world numbers depend on driving conditions, load, and maintenance.
