Unpopular position to tax gas more than diesel but,I agree. We have to stop paying terrorists to kill us.

So if the current passenger vehicle fleet is 235.4 M vehicles with 2.3-2.9% diesel, the answer is in a higher RATIO of diesel (alternative) passenger vehicle fleet.
A target is 23.4 % of the passenger vehicle fleet being diesel (alternative) for discussion purposes. (235.4 M x 23.4% would be 55.08 M diesel (alternative) vehicles
The answer is really in the RATIO's of "What Does One Barrel Of Crude Oil Make?"
1 barrel of crude (42 gals) yields grossly
gasoline 19.3 gals 46%
diesel 9.83 23.4%
A grade school understanding of math is all that is needed. But if there are any questions.... Fire away.
Not commonly known, but refiners to get unleaded regular and premium start with the much less available and much more expensive "light sweet crude", "Texas Tea" call it what one will.
The upshot: to make diesel, the more common OTHER THAN "light sweet crude" is both more available and 30-40% CHEAPER.
This is for starters there is also an ancillary internal rate of return.

It is good to know the %'s of light sweet crude.
Process GAIN is the last line item on the EIA figures. It is 2.47 gals/42 app a 6 % gain. Or the new figure is 44.47 gals. It is still 30-40% CHEAPER to buy "OTHER THAN" light sweet crude, which is more plentiful and available to process both unleaded regular and diesel. Indeed diesel's yield is still more both vol and %.
Seems like your post is making even a stronger case for HIGHER diesel use, i.e. greater percentage diesel passenger vehicle fleet. If we were processing ONLY (for CA) the new % of diesel passenger vehicle fleet would be 15.3%.
Again if you are not in favor of diesel (alternative fuel) you still haven't explained how using unleaded regular/ premium (97%) is going to make a dent in the LOWER % of unleaded regular/premium % use.

NICE with the ratio idea, ruking. i might just have to go to a 100% diesel personal fleet until the USA gets a balanced diesel/gas fleet! the 3 new D-C diesel SUVs look veeeeeery interesting - i might trade both my gassers (GTO+XC90) for one diesel D-C SUV.

IMAGINE if all those diesel products that used diesel, jet fuel etc were banned and required to go to a fuel source such as unleaded regular/premium.!!??... Unleaded fuel usage would got UP a min of 50%.
Fully one half of ALL fuel burned in this country IS diesel/Jet fuel/ home heating oil.
A short list would include emergency generators, house furnances, air planes, industrial processes, farm equipment, construction equippment, shipping, military vehicles, mass transportation. Essentially diesel is the back bone of the energy equation.

You sure did. Nice work.

I recently read an interesting story on oil changes.
What caught my eye was the following:
"These days, it’s common to hear of documented engine life of 500k miles and more. A fleet of Chevy gasoline V8 pickups pulling trailers delivering car parts overnight all over the Midwest has run a number of bow tie bombers to over 600K without failure. A 1987 Saab 900 just hit the million mile mark without an engine rebuild."
In the past super high mileage was the exclusive domain of diesels, or at least that was the conventional wisdom. It now appears that gasoline engines are starting to crash the 500K party.
I did double check to see what type of engine the Saab had in 87. It was either:
# 1986–1989 — 2.0 L (1985 cc) B201 Intercooled turbo, 138-155 hp/103-114 kW at 5000 rpm and 235 N·m (173 ft·lbf)
# 1984–1993 — 2.0 L (1985 cc) B202 16-valve turbo, 160-175 hp/118-129 kW at 5500 rpm and 255-273 N·m (188-201 ft·lbf)
