Good news is yes, I do and also Olivier on here and a few others, I'm on 100% WVO at the mo. but as ever there are advisories.
I think the best thing you can do is to have a look at this site -
vegetableoildiesel.co.uk - Powered by XMB
Some great advice there, have a GOOD read.
If it's you fist time on veg you'll most probably have 'issues' with your tank strainer block as the fuel tank coating is disintegrated by the WVO
, again good advice on the above site.
Enjoy virtually free fuel

what way do you filter the wvo i just used the jay cloth and siv method then added some white spirit will let it lie for 28days and drain off the good stuf dose this sound about right hope so and thanks

The way a lot do it is similar to you but they rough filter 1st, say an old bed sheet, heat up to 70/80C, let it stand for as long as possible, a week at least, tap off the good stuff at the top and filter down to 1 micron.
Then do a hot pan test, to test for moisture.
That's the basic quick explanation but you do need to have a look at

more info in there than I can give on here.

I'd say use a twin tank system just to be on the safe side. I was using 90% SVO and 10% derv for 22,000 miles until it caused the piston rings to gum on my C250TD
Vegetable oil used as fuel
"With unmodified engines the unfavorable effects may be reduced by blending, or "cutting", the SVO/PPO with diesel fuel; however, opinions vary as to the efficiacy of this. Some WVO mechanics have found higher rates of wear and failure in fuel pumps and piston rings.
(Although the old Merc Bosch in line diesel fuel pumps are nearly capable of pumping treacle long term so the piston gumming is the main thing to watch out for.)
This can generally be attributed to the use of oils with properties or contaminants that make them unsuitable for use in this type of application, poorly maintained engines, unsuitable engine modifications or operating regimes."

i was going to use a max of 50/50 but more 0f 60 derv 40 wvo *****ly this should be ok i would use good engine oil and change it every 5 to 6k what you think ..... before i put it in........

oh and what if i do 3 thanks 0f 50 50 then one of just 100 derv
Hiya,
I run on 10% diesel, put an odd 1 litre of unleaded in the mix, no bother. No need for 2 tanks. In winter last yeat I runned on 15% diesel and an odd litres of unleaded in the full tank.
No bother starting. Still going strong.
You will need to get few fuel filters as the oil will clean your pipes, also the tank strainer need to be cleaned ( its a pain, a real pain to remove), after that you should be fine.
Where are you located?

hope to god it works going to stick with 60derv 40wvo at first with the odd tank of derv will change the filter after 2nd tank then oil and filter
Funny as I just bought one of those coffee filters two days ago in lakeland, but I would only use it as prefiltering, better to go down to 1 micron after.
Filter socks are good. this is what I am using. They take some of the moisture away as well.

>>no bother
That's not strictly true though is it Olivier?
It seems to me that the veg oil advocates seem to play down any problems their cars have, or attribute them to other causes than the cheap and nasty fuel.
Fair play to future oils for mentioning piston ring gumming. It's the real concern, and the resulting engine strip down and repair is not cheap - it will wipe out any savings by running comedy fuel imediately.
These cars were designed to run on diesel fuel - from the pump, conforming to the relevant European standards, not the rejected oil from the local chippy passed through an old bedsheet.

I'm gutted, I was writing all that I change in the car and the laptop died on me. Grrr..
Anyway NC, I'll do a brief one then, all I did was not oil related, they were just normal wear and tear on a 100,000 miles car and I did the maintenance as I can be facy, new injectors, new glows, new clear lines, new rubber pipes, cleaned the strainer, engine mounts, gear box mounts, etc... This as nothing to do with oil or diesel at all.
About the ring gumming, it does happen indeed and this could be very costly. There is a nice member here Musher who had this happen to him, it went through a lot of trouble but fix it with soaking the cilynder with diesel and something else, I wish I remember what it was, could be handy
As long as you keep the ratio at a minimum of 10% diesel you should be fine, but everyone take a risk. Also mercedes will have other costly repair that need to be done even with only running on diesel, the ring gumming make the big news as this is oil related but what is the % of car running on oil that have had their ring gummed? Not that many I would think.
NC, you are trully against oil, why?
All the best.

I don't think that's true.
I voice the opposite view of the blinkered advocates because it can and does ruin perfectly good cars - truly ruining the ship for an 'apporth of tar.
It adds a new hazard in buying an older MB diesel, you need to be on your guard for the previous owners fuel related greed and guilibility.
These cars were designed, engineered and developed to run on diesel. Full stop.

If there was one mod I would recommend when running wvo/svo it's to advance the injection timing -
With the MB mechanical systems (fabled Bosch in line pump) there is no way to allow for wear (chain) other than to physically move the IP -
Running svo/wvo will retard the ignition by a small factor so to allow for this you need to advance it by 2/3 degrees
BUT.... here's where I think a lot of the problems occur; the older MB's have a reputation for running veg oil as is, and whilst this may have been true when they were in tip top condition it may no longer be so 10 years down the road when the chain is worn -
So you may purchase a good well cared for MB with timing already retarded due to it's age (this is partially MB's fault for making a engine that will run on paint stripper poured out of a rusty can
)
In total your older MB may need as much as 5/6 degrees movement of the IP to run properly on veg with minimal risk -

30k on and 80 to 100% veg all the way and no major issues apart from the DVS replacement, o-rings and the tank strainer + usual fuel filter changes.
it could be argued that all these things were in a bad state at 200k anyway and could do with changing regardless of fuel used.
saying that, WVO has never touched my car - i only use brand new rapeseed.
i'd also ONLY recommend use of SVO if you are handy with spanners as you will need to mess around changing stuff - labour in mechanic fees would not be worthwhile if you had to pay someone to do it. definatly a DIY-car owners pursute IMO

Diesel engines are pretty tolerant of a range of diesel fuels.
Not all diesel oil is the same - There can be significant variations in chemical composition.
That's one of the reasons I use Millers additive and disagree with those who say that it is inadvisable.
BUT
I do agree with Number Cruncher's view of using wvo in my E300TD and would not want to risk the cost and inconvenience of serious damage.
The engine was designed by very clever engineers specifically for diesel fuel.
If I can enhance that fuel by using a small amount of Millers - That's fine.
Wvo offers no enhancement - Quite the reverse.
The risks of contamination and associated gummy deposits are just too high-risk.
That's an honest opinion.
I'm not in the pockets of the fuel companies.
I just see it as too risky.
