How to Check Your Forester's Fuel Capacity

Signs Your Fuel Tank May Have Issues
- Fuel gauge drops faster than usual (possible leak).
- Strong gasoline odor near the vehicle.
- Check Engine Light with fuel-related codes (e.g., P0455).
- Difficulty filling the tank (clogged evaporative system).
Maximizing Fuel Efficiency
- Use cruise control on highways to maintain steady speeds.
- Remove excess weight (e.g., unused roof boxes).
- Keep tires inflated to 32-35 PSI (check door jamb sticker).
- Avoid idling for more than 30 seconds.
- Service the air filter every 30,000 miles.
