that's approx. how many barrels of crude refined in the U.S. each day.if one barrel equates to roughly 45% gas and 1.2% lubricants how can extending or monitoring OCI's save oil? demand would be less but the supply would increase.also this is an inelastic demand, you can't make your own.this would result in an upward price spike we are already seeing. the backside impact on the environment would be the same just delayed.I think this is why we see these major oil give-aways(rebates) every now and then.can we consume 192,000 barrels of Motor oil per day based on a ratio of gas used compared to miles driven? this does not take into consideration the impact of true synthetics either.
