      It amazes me that people like burning fossil fuels. I hate it. Sure, right now it's necessary to do so, but there's no reason we should put this issue on the backburner. get involved, buy a hybrid car (suv), vote to increase funding for alternative fuel research..

      We need to anticipate the problem instead of procrastinating the problem...

I agree with you tho..... car companies should look into what europe has..... alot of highly efficient Small Diesel motors..... the new jeep liberty comes with a tank full of Diesel, made of soy bean extract, and Its supposed to cut down on emmisions by alot..... ( exactly how many beans would It take to make a 19 gallon tank of diesel????)

        Well I don't mean to shock anybody, but my car has been running on old, used canola (rapeseed) oil from deep fryers since July of 2004. I have a few reataurants that supply me with their old oil (in fact they're happy that I'll take it, otherwise they'd have to pay for the disposal). I then take the oil and filter it. After it's filtered, I put it into a "jerry" can till I need to fuel up. When it's time to fill up, I pour the stuff into my car's tank, with about 20% regualr diesel and about 3-5% petroleum (kerosene). The petroleum brings down the oil's viscosity to roughly that of diesel's. It's important, cause vegetable oil has a fairly high viscosity, which makes it hard on injector pumps.

        What I'm doing is not to be confused with "biodiesel". Biodiesel is 80% vegetable oil and 20% methanol (or ethanol) by volume and is turned into RME (rapeseed methyl esther) through a chemical process. I'm using a pure waste product and using it as a viable fuel.What I'm doing also does not work with newer diesel cars with high injection pressures.

        The advantages of using used vegetable oil over diesel are:
        -price (it costs me about 20 cents per liter to fill up instead of 1.00 Euro for diesel)
        -less soot out of the tailpipe cause it cause the car runs leaner (due to the slightly lower BTU value of veggie oil)
        -no sulphur dioxide emissions (veggie oil contains no sulphur, while diesel does)
        -lower CO2 emissions
        -closed CO2 cycle (the CO2 that is emitted into the atmosphere during combustion is EQUAL to the amount of CO2 absorbed by the plants from which the oil is made)
        -no additional energy wasted on production (since it's 100% a waste product)
        -100% biodegradeable within a week of accidental spillage

        Here are some disadvantages of using used veggie oil
        -a bit of a pain in the butt (timewise)
        -cold weather requires you to raise the proportion of viscosity-reducing additives (like diesel or petroleum)
        -requires you to carry extra fuel filters and tool to change them at all times (veggie oil is a mild solvent)
        -people tell you that your car smells like a deep fryer from behind
        -NOX (nitrous oxide) emissions slightly higher than with diesel (due to the leaner, thus hotter combustion temperatures)

        I even made the papers with this (sorry, it's in German) :

          and then you get guys driving 429 muscle cars

          get 5-15 mpg and are more effecient in some ways... ie the old cars don't need replacing every 2-4 years like the new plastic ones do...

            I saw somewhere that a US tank (I forget the exact type) averages 440 yards a gallon...
