>>I have one question that comes from a long time understanding (or perhaps
>> misconception) concerning diesel v. gasoline...
>>
>> 1)  Diesel has a higher energy content per gallon than gasoline
>> (confirmed
>> in email below)
>> 2)  Diesel is not as highly refined as gasoline  (confirmed in email
>> below)
>> 3)  You get *MORE* diesel per gallon of crude oil than gasoline since
>> gasoline is more highly refined, thus removing more actual content from
>> the
>> crude oil.  (seems to be the logical conclusion of #1 and #2)
>> 4)  Wasn't it 2000 or 2001 that VW had the lowest pollution (non-hybird,
>> non-electric) vehicle being sold in the USA ... the Golf Diesel?  And
>> despite being the lowest polluting, California banned its sale because it
>> was a diesel!!
>>
>> If #3 is not true, then can you explain how it actually takes more crude
>> oil
>> per gallon of refined fuel to produce diesel than gasoline?
>>
>> Also, what is the energy input per gallon of gasoline for the additives
>> that
>> are used (detergents, anti-knock formulations, ethanol, etc) compared to
>> those added to diesel?
>>
>> Thanks,
