The Subaru Crosstrek holds 16.6 gallons of gas.
The Crosstrek's fuel tank capacity is 16.6 gallons across most trims. This allows for a driving range of 300-400 miles on a full tank, depending on engine type (standard or hybrid) and driving conditions. Fuel efficiency varies, with EPA estimates around 28-34 MPG combined.
Fuel Capacity by Model Year
- 2018-2024: 16.6 gallons (all trims)
- Hybrid models: Same tank size, but electric assist improves range.
- Older models (pre-2018): May vary slightly; verify specifications.
Factors Affecting Real-World Range
- Driving habits: Aggressive acceleration reduces MPG by up to 30%.
- Terrain: Hilly areas or off-road use increase fuel consumption.
- Load: Roof racks or heavy cargo lower efficiency by 2-8 MPG.
- Fuel type: Requires 87 octane (regular unleaded); premium offers no benefit.

Tips to Maximize Fuel Efficiency
- Tire pressure: Keep at manufacturer-recommended PSI (check door jamb sticker).
- Maintenance: Replace air filters and use synthetic oil for reduced engine strain.
- Cruise control: Use on highways to maintain steady speeds.
- Avoid idling: Turn off the engine if stopped for >30 seconds.
- Lighten load: Remove unnecessary roof boxes or trunk weight.
Warning Signs of Fuel System Issues
- Premature fuel pump failure: Whining noise from the rear (tank area).
- Clogged fuel filter: Sputtering at high speeds or difficulty starting.
- Fuel gauge inaccuracies: Sudden drops or stuck readings may indicate a faulty sender unit.
