In 1982 the average was 4mpg.
Currently, in 2006 the average is 6mpg.
Sometimes, depending on the terrain traveled most frequently, eg; mountains or plains, mpg varies drastically.
The highest average I have witnessed is 9mpg.
The lowest I have witnesses is 1.75mpg.
A military tank with the same diesel engine can average 2 gallons per mile. That is not a typo.

There has to be a better cheaper way to transport things . What if they ran on used cooking oil.What a saving that would be . Also less pollution.
