This is one thing to do with using old oil, but the problem, and it IS a problem, is that larger vehicles are being driven than need to be.
In the DC area, and anywhere there is a high concentration of the well-to-do, folks are driving around one and two passengers to a vehicle in behometh sport utes when a much smaller vehicle will do. These things burn 12, 15 mpg, pollute more, destroy most any car in their path in a crash (while not really being terribly crashworthy in and of themselves in spite of the false contention that they're "safer"), and take many times more resources to build than a car to begin with. In short, they're a nuisance. There's no denying it, polishing it up, or explaining it away.
That folks are free to buy them, drive them, and waste away doesn't justify it. Plus, 99% of em are simply a "look at me" statement. They aren't driven off-road, and rarely carry more than a couple or three people, around here anyway. They are a blight. Almost all of them aren't "needed", they're wanted. There's a difference.
In addition, our guys are by necessity fighting and dying by the thousands over there for the oil (and that IS what they're doing, by extension), and we're needlessly burning crude at prodigeous rates when we should be saving it for aviation, fertilizers and plastics for which there IS no substitue. We shouldn't be burning one drop of oil for electricity, either. It should ALL be generated by nuclear. Greenpeace should be ashamed.
And, we're providing those fascist mopes with the capitol with which to cause trouble the world over. Iran's upcoming nuclear capability is a case in point. Do I advocate the banning of Sport Utes? Nope. Everyone that hogs the gasoline that way has the right. Have at it.
In turn, the rest of us have the right to heap scorn upon them. We're paying a terrible price for the vanity of fools, and will regret it in the future one way or another. The little things you doods are proposing is good, but hardly effective absent other measures. Hey, if I'm wrong with any of this, I'm all ears. Show me where.
Ok, I'll climb off the soapbox now. An associate's nephew died over there last week, and things are starting to hit pretty close to home these days.
