Fuel Saving Tips
If you want the best fuel economy, avoid turning on the air conditioning at all costs. It doesn't matter if you're going 70, 80, or 90. Drag is nowhere close to being as detrimental to your fuel economy as AC is. It's almost always a guarantee that I hit between 170-180 miles at the 3/4 mark. The three times I used AC continuously, I was between the 130-140 range at the 3/4 mark. Using AC makes a HUGE difference.
