not really...the additives aren't expensive..but the price is regulated by the R/P ratio...
read what i posted in blue above.
gasoline is worth about 12 cent a gallon without the R/P ratio. but the R/P ratio prices gas accordingly to what execs state should be what we would be paying if crude oil on earth was running out within the next 20-40 years.
So basically the price we pay at the pump is soley based on the presumption that gas will run out completely between the next 20-40 yrs...this is done on purpose as a fail safe to buffer anything number of things (such as war, refinery problems, technology advances, environmental legislation, etc...) that can prevent or hinder crude oil from going from the oil beds to the pumps.
when in reality based on what fossil fuels/crude oil we have gasoline production will run out with in the next 900 to 10,000 yrs or centuries to millennia.
If we were paying for gas to reflect this fact that crude oil is not running out until after 900 yrs then gasoline at the pump would be somewhere between free and 12 cents a gallon.
