Diesel weighs about 7 pounds per gallon, and gasoline weighs about 6 pounds
per gallon. For comparison, fresh water weighs about 8 pounds per gallon
while seawater (not just saltwater) weighs about 9 pounds per gallon.

So your argument is backwards. The real reasons are:

1. less volatile than gasoline
2. more fuel efficient
3. more reliable (less prone to breakdowns)
4. less complex, therefore easier to maintain - an important consideration
when one is hundreds or possibly thousands of miles from decent maintenance
