After searching for the real costs of drilling and refining. . .they are not that available. So I'll assume the ideals. I'll assume the the goods are produced in Houston Texas(no travel to refinery), that the ratio is 2.21(2.21 and then some) of crude to product, and that the shipping is pollutant free to wherever it goes. Also we'll assume 1 gal = 3 liters for convenience(its 3.8 liters but whatever)
Well say for convenience and underestimates that we need to move the crude only 1 km straight up, that crude oil is 1/2 as heavy as water, gravity is 9.8.
The government estimates that coal power produces 2.17 lbs of CO2 per KWh
it takes 4,900 joules to move the oil to surface. No packaging flows directly into refinery. it takes 2.21 gallons of crude to make one gallon of gas. It takes more than 1 watt to drag the juice to surface. so it takes 5.98 lbs of CO2 for electricity for just the lifting of one gallon of gas. Your car at best (stochiometrically) can produce 20 lbs of CO2 per gallon.
Now IRL its going to cost a substantial amount of power to distill gasoline/diesel. if it even matches that weak 1 watt per GALLON 2/3 of the emissions from my car "produces" comes from the lifting and refinement.
The average gallon of crude now lies further than 5,600 feet below the surface(not including any ocean that has to be lifted through. Thats almost twice as far as my estimates and that was in 2005. over 4 years the average depth has sunk 900 ft. so we'll be conservative and say 200 ft per year. 3 more years 600 more feet. so half the emissions I produce through my car are strictly from the manufacture of gasoline. Trucking it to me adds but computing that is pointless unless you wanna tell me exactly where you live and the nearest pipeline depot and where your average fill happens. also the average barrel of oil does not come from right outside Houston Texas. so it has to be trucked there and twice of much of it has to be moved because it has to be refined.
I can only hope you are beginning to see that the manufacture of gasoline using underestimates is much greater than the MOST POSSIBLE emissions it can create.
If not then give me the numbers on what gas station you fill up on or the middle of the city you fill up in. and I'll start digging for the actual power needed to convert crude and the average distance a barrell travels before refinement
