Is it really that big a deal?
Your driving habits, like speeding and rapid acceleration, can cut into your fuel use by up to 30%!
The graph below from from fueleconomy.gov shows the direct effect of speed on the miles per gallon your vehicle maintains.
According to MPGforSpeed.com this effect happens for two reasons:
1) Increasing air resistance. According to CNN, "Pushing air around actually takes up about 40% of a car's energy at highway speeds. Traveling faster makes the job even harder...The increase is actually exponential, meaning wind resistance rises much more steeply between 70 and 80 mph than it does between 50 and 60. "
2) Engines are designed for specific speed, temperature, and rpm ranges. Driving out of these ranges goes against the fundamental design of the engine.
Interesting Facts If the national speed limit were reset to 55, it would save 1 billion barrels of oil per year.

Remember back in the 70's when they made the national speed limit 55 mph? There was much research behind the theory that this would help the energy crisis and applying it personally can still address the cost of fuel for us today. Savings on fuel can give us an extra night eating out on the road or a fancy gadget for our RV. Happy RVing!
