To the person who wrote about california smog, there are some counties in CA that don't do smog tests AT ALL (google it, or check DMV).

I believe like the OP and others that, with the rise of certain political ideas, platforms and politicians (in CA we have a super-majority of democrats who are all environmentalists), that it's just a matter of time until diesel cars of our vintage are classified as gross polluters. Remember that just a couple years ago, they literally DOUBLED the smog requirements in CA! That already put a lot of gasser MBZ owners 'out of business' (i.e. no more Mercedes driving, or get an illegal smog and pay $200+ to drive every two years, or by forging your location to the DMV as some have done. Small price to pay someone to 'pass you', but for some, it's cheaper than the fix required to bring your car into the acceptable smog level according to the state).

The bottom line is that as time goes bye, with trends going the way they are, our diesel cars are going to be harder to keep legal, without special exemptions. Europe is more socialist than America, so they will fall first. And then it will be California, and other states will follow suit.

To those in California who love their Benzes just as much as others love their guns, Arizona is always an option

you know, all those people talking about california.. you know you can do whatever modification you want to these old diesels because unlike some states, theres no one poking their nose around under your hood every year to pass you on inspection.. yeah you can remove that EGR and trap ox here. yeah no one ever mentions that. funny.

nor do they mention people that live near one of the ports, such as oakland, where diesel use and trucks idling has caused neighborhoods to have asthma rates multitudes higher than normal... or so much lead and heavy metals in the soil that it's unusable without special special precautions..yeah i guess no one out there has kids, do they?

oh and the hand wringing about "environmentalists"... well a lot of those people are the ones keeping the diesel benz community alive. running on biodiesel.. and waste veggie oil.. so yeah... eyeroll

This is based on the population of certain counties. Usually, very mountainous regions. Catalina Island doesn't smog either, IIRC...

Back in the summer of 2005, diesel in Fresno was over $5.00/gallon. At that time, I could buy a 5 gallon bladder of vegetable oil from Costco for $28.00 and we ran the 300SD on pure VVO for almost a year, without any modifications of any kind.

Now, I find it interesting that VVO is now MORE than diesel. If the price ever drops, I will go back to 100% VVO.

I even did tests on VVO in the refrigerator and adding the Diesel Klean Anti-Gel kept it from coagulating at low temperatures.

We started that motor on VVO with additive in Big Bear in December at 29°F with no issues whatsoever, just one, full glow cycle and it was running.

Makes more SOP power on VVO and smells like the KFC trash hopper.

It really would be better for the environment, IMHO...

And a bit more on the topic:

Oslo mulls winter ban on diesel cars - The Local

Norway May Ban Diesel Cars - The Nordic Page - Panorama

In California, CARB is only one of the big opponents of diesels, but the proposed CARB regulations should not be confused with the rules drafted by the South Coast Air Quality Management District—adopted in 2000 and later invalidated by US Supreme Court—which attempted to ban the purchase of diesel vehicles, regardless of their PM emission level.

The first paragraph in this article says it all: http://www.science20.com/news_articles/ban_cars_air_improves_los_angeles_when_autos_are_gone-94629

"In 2008, China needed to improve the air around Beijing before the Olympics, so they did something that was considered Draconian - they banned cars for everyone except the rich and the government....."

And from the SAME science magazine that wrote the China article above, comes this bizarre twist:

As pointed out there are alternatives to running real diesel. Perhaps this is the future for most of us?

Does anyone know of any sources of data the show what kind of pollutants are produced by burning alternatives to diesel?

Saw a few years back that in Japan licensing vehicles was the inverse of what we typically do here. Meaning a new car, registers free. Then every year thereafter it goes up and up and up. One reason you can see folks importing classic - well "classic" Japanese cars like old 240 and 260Z's with low mileage - as folks can't afford to license them anymore...

Army-
When you use biodiesel (versus petro-diesel), emissions of particles typically drops and emissions of oxides of nitrogen (NOx) typically goes up. PM is a bigger direct health concern to those near diesels, whereas NOx contributes to the formation of ozone and acid rain. Net CO2 emissions are lower because the plants sucked the CO2 in which is emitted as you drive. But biodiesel is not climate neutral. It takes a lot of energy to grow the plants and process the fuel. So there are CO2 reductions with biodiesel compared to petrodiesel, but it is far from perfect.

There is tons of research (much of it in the SAE journals) on emissions of alternatives fuels. I don't have it in front of me, but I am happy to help people track down emissions data for a particular fuel if interested.

Eastern San Diego county (i.e. Julian/Alpine) only smogs at purchase.

Well if you can suggest a few SAE articles I'll either ask a friend who teaches at a University locally to get me a copy or pop off down to the local library.

A quick look on google scholar searching for "biodiesel pollution" came up with this PDF

http://www.cti2000.it/Bionett/BioD-1999-101%20Biodiesel%20production%20review.pdf

This is the first time I've actually seen some published chemical models of how things are meant to behave. Most of the information out there (that I can find anyway) is presented in the argumentative "myth" / "fact" dumbed down for the masses BS format...

...which makes it very difficult to make an informed opinion.

But for statewide policies concerning automotive emissions, they hold the most sway.

For further reading, look at the credentials of all those who serve the public and political interests with CARB. I could only identify one engineer, and one person with hazardous waste management experience. Everyone else seemed to be either teachers, career politicians or physicians. Not that these career fields would not prepare one for representing public concern, but would it not be a better balance with more engineering and scientific involvement?
