• Terrain and trip type: frequent stop-and-go city driving and steep hills lower mpg compared with steady highway cruising.


• Maintenance and condition: proper tire pressure, timely engine tune-ups, and clean air filters help sustain efficiency.


• Transmission choice: manual vs. automatic can yield different mpg figures, especially under varying driving conditions.


• Load and accessories: roof racks, extra weight, and aerodynamic drag reduce overall fuel economy.

To maximize mileage, maintain proper tire inflation, adopt smoother driving habits, and follow the manufacturer’s maintenance schedule. Real-world results will still vary from the EPA estimates based on how and where the car is driven.

Summary

The Acura TSX generally delivers mid-20s fuel economy across its production years, with typical combined mileage around 25–28 mpg depending on year, engine configuration, and transmission. For precise figures, consult the EPA ratings for a specific model year, and consider your driving style and maintenance habits when estimating real-world mileage. Though the model is no longer in production, older TSX data remains useful for buyers and enthusiasts evaluating fuel efficiency history.
