Well technically it was invented to burn coal dust, but that's another story.

====================================
Rudolf Diesel originally tried to design an engine that would run on coal dust, because the Brits and the Americans had oil, but the Germans did not. A prototype of this original engine caused an explosion so loud that poor Rudy was deaf in one ear for the rest of his life.

George Washington Carver several years before had discovered many, many uses for penuts (curiously, though, peanut butter was not one of them), and since peanuts will grow in the Reich, Rudolph restated his objectives, probably not wishing to be entirely deaf.

Noe of this means that YOUR Benz was designed to run on peanut oil or coal dust, by the way. It perhaps SHOULD be able to do this, but should and can are different words.

I was thinking of trying a can of Crisco in my car to see if that would work, or how about a pound of lard?? I am sure that I will have to install a pre-heater to get the "fuel" to flow properly......Just amazing stuff people will try on these fantastic diesel engines!!

That is BS that BioD set off limp home mode because the emissions were too low. It was probably the poor fuel quality that made the CEL go on, as well as putting the car into Limp Home Mode. Once you mixed it with diesel it diluted the poor bio quality. I do not see how low emissions would make a CEL come on. I could however see how poor fuel quality could make the CEL come on and once you added diesel it lessened the effects of the poor quality bio and made it acceptable quality.

It's also possible that the high bio blend was clogging the particulate filter. I don't know exactly how MB designed the filter purging to work, but I've heard that VW injects extra fuel every now and then to purge the filter and this only works when you're burning fuel that burns exactly like diesel. Bio has lower volatility and slightly higher viscosity than diesel.

hahahaha i know ive become a jackass but im for sure not suffering little man's syndrome. But i am the top salesman and i love to brag about it.

This thread has gone way off course though. Imma side with husk, i think it has to do with the quality of the bio. The only reason MB, VW, Dodge, etc limit their diesel vehicles to B5 is for the lack of mandated quality checks.
The Euro specs for biodiesel are virtually the same for the US ASTM specs so just as long as the biodiesel you put into your E320 meet the specs you shouldnt have done any harm to the car.

I remember some old threads about someone claiming that biodiesel produced an ash or some crap that would harm the bluetech system which doesnt make sense to me. If Biodiesel produces less pollutants then ULSD how can it harm the emission system?

Unless the computer has a problem coping with the higher cetane putting it into limp mode?

I don't know many cares salesmen, just one and he is slick.

But the RE agents that I know that will make $300k-$1M+ this year do not have that attitude. That attitude will not let you ever acheive those numbers either.

This is the document I was talking about:
http://biodiesel.org/pdf_files/fuelfactsheets/Use_of_Biodiesel_Blends_above_%2020.pdf

It explains the potential dangers of using more than B20.

crashone · #67 07-16-2008, 07:52 PM

Damn.... I guess it's all a matter of perspective. I cannot afford an '08 CDI. Or an '05. I wish I could own an '08. I would probably cream my jeans if I did. But man this guy must have more cash than..... ahhh what the hell. Drive it like you stole it dude.

Life is short.

Cummins has allowed B20 for most engines produced after 2002. It includes the new 6.7. You can read the press release here.

I'm glad to hear your car is back to normal and it was just a fuel issue!

Here are my thoughts about Biodiesel and a $50k car:

Buy a Rusty old early 80's 300d for $500, fix all the accessories you prefer. Drive it on WVO, Bio or whatever. I doubt it'll give you many issues. When it dies, buy another one.

You'll still be ahead financially if you do that 20 - 30 times vs. buying a CDI.

But of course it'll be an old rusty car that you won't feel good about. But what's 'feel good about' worth in a dollar value? Not that much to me. But I bought this (my daily drive) for $500 and it's been a nice car. The best deal I've had yet on a MB. Most of mine have been under $1000 and all ran great.

Not that spending $50k on a car is a bad investment, but as Jeremy said, if you're going to take risks, it's a better investment to do it on something that's not got such a high upfront cost. But of course, you may have more money than you know what to do with. I still think there are better places to put the money though. I think I'd change my auto buying ideas only slightly no matter how much my annual income grew. Cars are not an investment. But you do have to admit they are fun. Still... go out and buy an old one and you won't have to worry about Service Engine lights coming on because their are none!

If you bought that W124 for $500 bucks, all I can say is "wow"! I missed one here a few weeks ago for $2K and felt like one slipped away.
Wow!

Must be a cali thing, but most RE agents ive sold a car to are just as big of a prick as i am. And they are all buying used honda's

........$300K-$1M......

Hatterasguy · #74 07-17-2008, 07:16 PM

Thats why they are buying used Honda's.

Yep! I bought it as a donated Salvation Army vehicle. They wanted $900 for it. I checked it out mid-winter and I could barely crank it over. It hadn't been started in around 2 years. But long story short, I took a gamble on it running or not. I told them I'd be taking a risk and they said $500 was good enough. Since then I've restored all kinds of suspension stuff, A/C parts, ruined brittle rubber parts (just messed up the IP o ring seal-fun job for the next couple saturdays fixing!)

But all in all it's been a good car. Man have I put some hours into it. I think I have $2500 in the car including parts and I'm hoping to get another 100k out of it for that price. Right now it's at 170k. If the chain doesn't let loose or the Head crack, I'll be happy! I've checked it over pretty well. Hopefully God's on my side and it'll last me a while! I don't have the cash to buy a CDI! Lol. But if it ever blows it's head, back to 123's!! But boy I'll miss the power this has. I don't miss Gasoline at all. It's still no race-car (0-60 in around 11 seconds) but I'm more than happy with it's pep.
