How can I get better gas mileage?

Slow down (efficiency drops sharply above 100 km/h), inflate tires, remove roof racks, drop the excess weight, and avoid jackrabbit starts. Idling more than 30 seconds burns more than restarting.

Follow-up questions

Premium fuel — worth it?

Only if your manual requires it. Otherwise it's an expensive placebo.

Does AC really hurt mileage?

Yes, slightly. Below ~80 km/h, open windows are more efficient; above, AC wins.
