I have discovered a new product that makes your car burn gas so efficiently and cleanly that carbon monoxide emissions are reduced by 78% or more. Other smog elements also radically reduced, but carbon monoxide is the most pressing concern in global warming. I would gladly pay extra for such a product, yet it actually increases your mileage per gallon by 10-20-30%, so saves gas/oil as well as reducing smog emissions. I am new to this group and I don't know if including my URL would be considered spamming, so if you'd like info about this product (or if you'd like to inquire about this earth-friendly business), please write to me at CleanAirSaveGas@comcast.net. Or call me at 310 559-2870
