|gasoline or diesel better for environment?||DougSloan|

|Which would be considered better for the environment, a gasoline engine car or diesel that gets twice the fuel economy?
|Diesel for a couple of reasons...||firstrax|

|It spends less time in the refinery giving a higher yield per barrel of crude. Meaning 25% more diesel for a given amount of pollution than gas.
Almost no vapor loss at transfers and at the pump.
Add that to the mpg figures and its the clear winner.
Of course we all know the Segway is the transpo of the future

|You cant, would interfear with the spoiler. Dean has trailers for the segway. Maybe one could be modified for a bike.|
|Segway with a nitros oxide tank? Too cool.||Sintesi|

|Personally I'd like to see one with a lawn mowing attachment. It kind of looks like an old lawn mower anyway.|

|There are many things to consider. For trucks, diesel is the only way to go because of engine durability, fuel economy, and the much greater power band and torque that a diesel offers for pulling heavy loads.
But your question was for cars and what was better for the environment. Twice the fuel economy certainly puts it in favor of diesel. But I'm not sure that for the same car body you can achieve 2x the fuel mileage by putting a diesel. The only cars you can compare that to are VWs and some European or prototype Mercedes or BMWs. American diesels are pretty much limited to heavy duty pickup trucks and usually are chosen for more towing power than for economy.
And like the other poster said, refining/manufacturing a gallon of diesel takes much less of a toll in terms of pollution than a gallon of gasoline.
The only downside for diesel is the emissions coming out of the tailpipe. It looks pretty sooty and I read diesels have higer emissions for some things and lower than gasoline engines for others. Gasoline engines just don't have all that nasty soot coming out so people just think they are a lot cleaner.

|Not sure dont about the environment but if all cars were to switch over to diesel, the air pollution in large cities would sky rocket. The negative impact to the health of people living in congested areas may itself be detriment enough for sticking to cleaner burning fuels in cities.|

|but the particulates in the air (brown cloud) are not the bad stuff--rather the ozone which is odorless and invisible.|
|Diesel, if I have to pick.||MXL02|

|I think diesel burns dirtier, but gets better MPG, and you can make it at home...my brother who commutes in an RV, actually makes his own diesel. The best alternative is electric, once they get the fuel cell issue solved.|
|Make your own?||Fez|

|How does he make his own diesel?
I knew another guy that would buy kerosene (same stuff but dyed a different color) and run it in his diesel truck. Cheaper, but illegal to do so because diesel fuel was taxed higher so the penalties were stiff if you got caught.

|diesel is actually the same thing as home heating oil. Taxes are less on heating oil so some folks buy that. My source is the font of all car knowledge: Click and Clack.|| |
