If you mostly drive on the highway -> Look up speed vs mpg. Slowing down will increase your fuel efficiency. Going 55mph instead of 70 mph makes a big difference. As always look into increasing your tire pressure and the possibility of a upper grill block. A scan gauge or similar will be really helpful in finding what works and what doesn't. The driver really does make the biggest difference in fuel economy! Route planning can be really helpful to keep you moving and your speed low.
