How big is an Acura TL gas tank?
The Acura TL typically carries about 18.5 gallons (70 liters) of fuel in its tank, though the exact capacity can vary slightly by generation and trim. In this article, we break down the general figures by generation and show how to verify the precise size for your specific car.
Across the TL’s three main generations (1999–2014), the fuel-tank size remains broadly similar, but there are minor differences depending on year, engine choice, and emissions equipment. The following guide provides the typical range and how to confirm the exact figure for your vehicle.
Fuel-tank capacity by generation
Below is a general guide to tank sizes by TL generation. Exact figures may vary by trim or market, so always check your car’s labels or manual for the precise specification.
- 1999–2003 TL (2nd generation): approximately 18.5 gallons (70 L).
- 2004–2008 TL (3rd generation): approximately 18.5 gallons (70 L).
- 2009–2014 TL (4th generation): approximately 18.5 gallons (70 L).
In practice, Acura TL models across these years use a fuel tank around 18.5 gallons, with only minor variations. For an exact figure, consult the door-jamb fuel-filler label or the vehicle’s owner’s manual.
How to verify the exact capacity for your car
If you need the precise tank capacity for a specific TL, use these steps to confirm the figure for your exact vehicle:
- Check the fuel-filler door label, which often lists the capacity in gallons or liters.
- Refer to the owner’s manual or the official Acura/Honda service site using your VIN (vehicle identification number).
- Ask a dealer or a certified mechanic to pull the exact specification for your VIN.
These sources provide the official capacity; if your vehicle has undergone modifications or replacements affecting the fuel system, rely on the VIN-specific data from the dealer.
Planning range and fuel economy
Estimating range combines tank size with real-world fuel economy. The TL’s MPG varies by year and engine, but a typical combined figure is in the low 20s. Using a ballpark of 22–24 mpg combined, a full 18.5-gallon tank can yield roughly 400–450 miles under normal driving conditions. To tailor this to your car, multiply the actual miles-per-gallon you achieve by the tank’s capacity.
Summary
The Acura TL generally uses about 18.5 gallons of fuel in its tank, a figure that holds across its main generations with only minor deviations. For the exact capacity of your specific car, check the fuel-filler door label, the owner’s manual, or contact a dealership with your VIN. Understanding the tank size helps with planning range and fuel-efficiency expectations for daily driving or longer trips.
