I can't back this up -- this is purely anecdotal....

A barrel of oil will have a certain affinity for X gallons of diesel and Y gallons of gasoline. Both of which are extracted using a similar process at the same time (it's something like a furnace weight separator - not sure on the official name).

From that knowledge alone, I'd say that refining impact is similar...

I had a chart that was related to this very thing... But I can't find it... I did, however, find this interesting chart (which you may be interested in)...

and this one... The reserve to production ratios

Start here and investigate those terms associated with refining gasoline and USLD if possible. PM if ya bump up against any proprietary scienecy databases and want some more info.

I am interested in power with economy. Here are some links to performance guru Gale Banks web-sight that may intrest you. He discusses diesel as a an economical and performance choice.
