I would say less than 1 in 20 vehicles I see are driving with under inflated tires, because if you do, you'll have a blowout with economic conquences more severe than mearly waisting some gas. It's more common to see a car being driven with 4 donut tires than under inflated tires.faethor said:]You may. But, the general public? No.metalman said:Most drivers already regularly check their tire pressure
Cars haven't been built with ignition points and condensers since the late 70's. Modern engines have computer controls, electronic ignitions, oxygen sensors, platimun tipped spark plugs, fuel injection, and use unleaded gasoline. A modern engine can go 100,000-mile without needing a tune up. What is required now is engine maintenance. Change the oil, air filter, and add injector cleaner to the gas.faethor said:Yes they are better then older engines. However they do need maintenance.metalman said:and electronic ignition systems don't require constant tuning.
Example: I bought my 9-2x w/ 36K miles on her around 40K the mileage for 2 tanks in the row were 25ish MPG instead of 27 MPG. It appears the dealer didn't ensure that the 30K maintenance was done. I went back there and they did it for no cost. The next few tanks were 28MPG. So clearly having a properly tuned car does make a difference.
faethor said:Bush Admin documents say 1% gain in the next 30 years from drilling vs my 10% gain between a properly and improperly tuned engine. You do the math.metalman said:So to say that the energy savings from proper tire inflation will offset energy that could be obtained from offshore drilling is ignorant.
US annual oil consumption 759 million barrels
The Bakken Formation is now being developed using horizontal drilling technology. The Bakken Formation had its estimates of recoverable oil increased from none, to 4.5 billion barrels of recoverable oil.
ANWAR has 4.3 billion barrels of current technically recoverable oil
A 2008 United States Geological Survey estimates that the Arctic contains as much as 90 billion barrels of oil reserves (about 13 percent of the world's undiscovered reserves).
You do the math.
There is a fundamental difference between developing new energy resources and using less energy, whether through tire inflation, or changing from a jet plane to a turboprop. I don't need the government to tell me to maintain my vehicle. I'm already doing that. The ObamaMessssiah's obsession with tire inflation isn't an energy policy, it's a public service announcement.
