Fuel Saving Tips
Sometimes, when it's scorching hot, AC is a must. But if you have manual climate control or an A/C off button, you can be selective as to when your A/C compressor engages. Both in the city and on the highways, turn the A/C on when you're slowing down, and turn it off when you're accelerating. Instead of energy going to the brakes, it'll run your A/C without using any extra fuel. In a manual, keep the car in gear and your RPMs up while slowing down with the A/C on.
