1.   Since scale is a poor heat conductor, inefficient fuel usage soon becomes apparent.

2.   Authorities also have subpoenaed records from the gas company to determine when fuel usage might have dropped off.

3.   But as the shuttle fuel usage soared, NASA said it would have to stop the mapping well before Sunday night if it could not develop fuel conservation measures.

4.   But I got the feeling that you could almost calculate the fuel usage in gallons per mile than miles per gallon.

5.   Remember, the reduced speed limit was enacted not to increase safety, but to decrease fuel usage.

6.   The energy industry will feel this, because a big component of fuel usage is jet fuel, and that will go down.

7.   With the Aura system, a controller like the electronic fuel injector will determine fuel usage and the way to maximize horsepower.

8.   With a little forethought, you can reduce your daily fuel usage.

9.   A new dormitory building that combines super-insulation with solar panels has drastically cut heating fuel usage.

10.   They are designed to make steering and manoeuvring a cruise ship easier while achieving less fuel usage through improved hydrodynamic efficiencies.
