4. Fuel Economy and How Tank Size Affects It
Real‑World MPG Numbers
The A4 2.0 TFSI averages about 28–30 mpg city and 35–37 mpg highway. The 3.0 TFSI is a bit less efficient, around 23–25 mpg city and 30–32 mpg highway.
Calculating Range
Range = Fuel Capacity × MPG. For a 13.4‑gallon tank and 30 mpg highway:
- 13.4 gallons × 30 mpg = 402 miles.
That’s plenty for a weekend getaway!
Practical Tips to Maximize Range
- Maintain proper tire pressure.
- Avoid aggressive acceleration.
- Use cruise control on highways.
5. How to Check Your Fuel Level Quickly
Using the Dashboard Gauge
The A4’s gauge shows a simple “half” or “full” indicator. For precise monitoring, use the infotainment screen which displays the exact percentage.
Smartphone Apps
Apps like Fuelio or GasBuddy let you log refueling events and calculate average consumption.
When to Refuel
Don’t wait until the tank is completely empty. Refuel when you see the “empty” indicator or when the gauge hits the low‑fuel warning.
