I remember seeing years ago that after a cradle to the grave analysis, I think it was the Jeep Wrangler or similar that came out best because of their manufacturing processes and the hybrid vehicles were nowhere in sight.Quote:

Thats the same as unleaded fuel.Quote:

The news media overseas is more interested in the green credit tax payed out than the pollution.
I freely admit that I haven't done the Science on this, but indications are that the BAS remap has made my Defender more fuel efficient, at least on the Highway. So my question would be: Which gasses and how much of them are reduced by the EGR? Do they actually reduce emissions if they make vehicles less fuel efficient?
The Defender should also be given credit for it's longevity, given that, as I once read, more emissions are caused in the production of a vehicle than it will produce in it's life time.(On average).
Correct... In Adelaide they fitted Air Quality units on a few primary roads to test Lead levels pre and post Unleaded roll out.Quote:

It continues to rise...
When I was working for CAMS as a Scrutineer we had to inspect vehicles inside their garages at the tracks.. The big team bosses would often close the roller doors and start the vehicles - in an effort to encourage us to hurry up and leave... That stuff burns (and is highly carcinogenic)
Its the sweetest smelling and most addictive fume also! The sugar of exhausts! :DQuote:

What was that Castrol oil, Corse,(?) in the 70's that smelled oh so good, a rally car favorite. I wonder if you can get it in 5W30, i would buy it tomorrow.
Lead has also been linked to violet crime, mainly via brain damage to the young
Forbes Welcome
Now, who did more damage to the environment than any other individual, invented leaded fuel and fluorocarbons i believe. (No its not the CEO of VW :wasntme: )
Are we off topic yet :D
Back in the 60s, a friend of mine had a side valve Hillman. He used to pour a bottle of castor oil in the tank and remove a small plug screwed into the exhaust manifold.Quote:

The story in the Christian Science Monitor said the software detected the vehicle was being operated in the mode used for emissions testing (steady speed, stable revs, wheels straight ahead etc) and cut the fuel flow. Once the mode of operation changed it reverted to full fuelling, which increased emissions of nitrous oxides by up to 35 times depending on the model. Fuel economy might improve, but emssions results would breach the latest American rules. In other words, the cars were poisoning the atmosphere and people.

Oxymoron? ;)Quote:

The challenge is what we will accept, and which poison we will accept...
Benzine, NOx, CO, CO2, BPA, Toluene.. the list is endless...
Then we could go on about Radiation, Phones, Screens...
