How many gallons does an Acura TSX hold?

The Acura TSX, a popular luxury sedan, has a fuel tank capacity of 18.5 gallons. This means the TSX can hold up to 18.5 gallons of gasoline in its fuel tank.


Detailed Overview of the Acura TSX Fuel Tank Capacity


The Acura TSX is a midsize luxury car that has been in production since 2003. Over the years, the fuel tank capacity of the TSX has remained consistent at 18.5 gallons. This fuel tank size is typical for a vehicle in the TSX's class and provides a good balance between fuel efficiency and driving range.


The 18.5-gallon fuel tank allows the Acura TSX to have a respectable driving range on a single tank of gas. Depending on driving conditions and the vehicle's fuel efficiency, the TSX can typically travel between 350 to 450 miles before needing to refuel. This makes the TSX a practical choice for both city driving and longer road trips.


Factors That Affect Fuel Tank Capacity


The fuel tank capacity of a vehicle is determined by several factors, including the overall size and design of the vehicle, as well as engineering considerations. Larger vehicles, such as SUVs and trucks, generally have larger fuel tanks to accommodate their greater fuel consumption. Conversely, smaller, more fuel-efficient vehicles like the Acura TSX tend to have smaller fuel tanks.


Other factors that can influence a vehicle's fuel tank capacity include the placement of the fuel tank within the vehicle, the shape and size of the tank, and the overall packaging constraints of the vehicle's design. Manufacturers must balance fuel tank size with other design priorities, such as passenger and cargo space, to create a well-rounded and practical vehicle.


Comparing the Acura TSX to Similar Vehicles


When compared to other midsize luxury sedans, the Acura TSX's 18.5-gallon fuel tank capacity is on the higher end of the spectrum. For example, the BMW 3 Series has a fuel tank capacity of 15.6 gallons, while the Lexus ES has a 17.2-gallon tank. The Honda Accord, which shares some engineering with the TSX, has a 14.8-gallon fuel tank.


The larger fuel tank of the Acura TSX provides it with a slight advantage in terms of driving range and the ability to go longer between refueling stops. This can be particularly beneficial for drivers who frequently take long road trips or have a lengthy daily commute.

Does the Acura TSX only take premium gas?


While your Acura vehicle will run fine on regular gasoline, using the recommended premium unleaded 91-octane fuel is sure to boost performance, increase longevity, and keep your Acura running as it should – providing you with the peace of mind you've been seeking.

Can I mix premium and mid gas?


There's nothing wrong with mixing premium and regular gas in the same tank. In fact, this is how midgrade gas is formulated at the station. Rather than drawing from a separate storage tank for each octane rating, gas pumps actively mix high-octane fuel with lower-octane fuel to create midgrade gas.
