How big is the gas tank on the Acura RL?
The Acura RL’s gas tank is typically around 18.5 to 19 gallons (roughly 70 to 72 liters), depending on the model year and regional market.
The size matters for planning trips, estimating range, and budgeting fuel consumption. While the tank size is broadly similar across generations, exact figures can vary slightly by year, trim, and country. This article breaks down the typical capacities by RL generation and notes how to confirm the precise figure for a specific vehicle.
Generational differences in tank size
Below is a concise breakdown of typical tank sizes by RL generation, based on original US specifications and commonly published data.
- First-generation RL (late 1990s to early 2000s): typically about 18.5 gallons (roughly 70 liters).
- Second-generation RL (2005–2012): typically about 18.5 to 19.0 gallons (roughly 70–72 liters).
The vast majority of US-spec RL models use a tank in the high teens, with a minor increase for the later generation. For an exact figure, check the vehicle’s owner's manual or the fuel door placard.
Practical considerations for owners and buyers
Knowing the tank size helps with planning long trips, estimating range, and budgeting for fuel efficiency. The actual driving range depends on engine choice, transmission, and driving conditions, but the RL’s fuel capacity provides a practical framework for trip planning.
- Consider typical fuel economy. If your RL averages around 20 mpg combined, a full tank provides about 370 miles of range (18.5 gallons × 20 mpg).
- Verify the exact capacity on your specific car. Capacity can differ slightly by market (US vs. international), trim level, or model year.
In all cases, the best source for the precise figure is the owner's manual or the fuel-filler door placard on your car.
Summary
The Acura RL commonly uses a fuel tank in the high-teens—about 18.5 to 19 gallons—with small year-to-year variations. Knowing this helps with trip planning and fuel budgeting, and for exact figures, consult the owner's manual or the vehicle’s door placard.
