I'm in the process using recycled vegetable oil as fuel for my Mercedes. Does anybody have any thoughts on this? I've seen many different types of conversions available. What if any would you recommend?

IT YOU ARE GOING TO GO BIO YOU ARE GOING TO NEED TO REPLACE ALL OLD FUEL LINES AND ARE GOING TO HAVE TO WATCH OUT FOR THE RUBBER SEALS IN THE INJECTOR HOUSING THEY MAY SWELL ALONG WITH THE FUEL LINES YOU MIGHT ALSO FIND SOME OF THE SAME SEALS DETEAORTING DUE TO THE BIO FUEL YOU MIGHT WANT TO GO WITH A 80% DESIL &20% VEGETABLE OIL IT IS LESS HARSH TO THE SEALS CHECK OUT

I've been running my 1976 300D on 80% waste vegetable oil/20% diesel (now biodiesel) for the past year.
I haven't done any conversions, but their is a bit more white smoke in the exhaust (I only changed my fuel filters ONCE! Hopefully a change will rectify this).
I notice more black soot around the tailpipe, and I just took a glow plug out, and it was pretty black, but I think this would be the case regardless of fuel.
It starts up fine, even in winter (I live on the West Coast, so it's rather mild).
The only real problem I'm having is my glow plugs sometimes don't go on, and it won't start (I'm experiencing this right now), and the muffler system is rather worn. But in terms of engine performance, the 80/20 ratio works great

here's a good website on that subject, they're running a diesel on corn oil.
Good luck,

I have a 1982 300TD that I bought on eBay 1 1/2 years ago for the express purpose of converting to wvo. I have a friend who had a 300TD that was converted using a greasecar.com kit, and another who bought a greasel.com kit. Both kits had drawbacks, so I started from scratch. The goal is simple, have the oil between 150 and 170 degrees when it hits the injectors. Last year I went through a fair amount of trial and error. I made some major changes over the winter and reinstalled the system in the spring, that version of the system has worked well ever since. I just drove from CT to IL and back, almost entirely on wvo. I set a record with my last fill-up of diesel: 2648 miles on 13.2 gallons of diesel.

I hope to set up a web page at some point, as well as add up what the final system cost me. Less than a kit, I think.

If you want some pointers on this, let me know.

...2648 MILES ON 13.2 GAL OF DIESEL = 200.6 MILES PER GALLON !!!!
i assume there was some FAT burned during that trip also?

WHATS THE TOTAL COST OF THE CONVERSION PARTS ? $

COST OF THE 'FAT' IF ANY? - AND SOON THERE WILLBE
A COST WHEN THE COOKS FIGURE OUT DAT DAR'S GOLD IN
DEM DAR BUCKETS-0-FAT ? $

COST OF DIESEL FUEL IN YOUR AREA? $

CONSIDER THE LACK OF SYSTEM LUBRICATION WHEN NOT
INJECTING DIESEL FUEL - FAT DOES NOT LUBRICATE INJECTOR
PINTALS, INJECTION PUMP SPINNING & STROKING INTERNALS, CHECK VALVES,
CYLINDER BORE/PISTON RING WEAR ?

Here's a link to a site (some text in english) and how this guy solved the preheating problem. It's made to work in swedish winters (upper half is arctic).

So, what is your problem? If you check your engine regularly, use some engine cleaner once in a a while, there should be no problem. Over here in Europe there are examples of 250k to 280k kilometers driven on WVO or pure veggie oil from the supermarket.

When you check the injectors, replace the filters often enough there will be no problem.

Well, correction, it's better to drive on Rapeseed oil in the (very) long term.

Without a real conversion it's not a smart thing to do IMHO, even with this conversion, it's not even smart to run on WVO (only SVO, and then only certain SVO's). I used to think lightly about the subject too, but not anymore.
You need to adjust the injectors, glow plugs, filtering and heating, it's not just a matter of heating the fuel.
Also, WVO is a bad idea, unless you can titrate every liter you throw in. It's best, according to the specialists, to use fresh cold pressed rapeseed oil.

Check out Journeytoforever.org, I've learned a lot there.

I've got a W123 Elsbett 300td now, you can read about it (more) soon @ 300td.org

For the best, goto www.biofuels.ca. Ive been using heated veggie oil for 10 months in my VW with no adverse monetary side effects.
