I used to run on veg but soon moved to Bio as it is a direct replacement to diesel and doesn't need mixing etc. I'm sure over a long enough time there'll be some pump degradation but at a saving of over 40p a litre at today's pump prices I'll bung another s/h on eventually .
I spoke to Diesel Bob a few years back about Bio and injector mods for performance gains. He was of the opinion it was a black art and wasn't interested in helping. Once I said I had LPG injection already done he was more helpful :nenau

 

[AlexD333]

This is interesting, if I could find bio for around the 60-70p mark a litre I would happily convert, I pay 13.99 for 20l at the moment.

Infact yeah,that works out at 0.6995 a litre :thumb2

What the cons of bio then? More regular fuel filter changes?

If you can find it that cheap I'll have a few thousand litres of it :sly
Bio will defo clean out your tank of crud and so yes a few filters needed when you start but no big deal.
Benefit is it needs no mixing with anything. A few years ago when we had that cold snowy winter, I had the truck running on bio at -15 and no issues.
It still needs good glow plugs in the cold but you save as there's no diesel or petrol or redex to add to it thus diluting the saving :thumbs
My friend runs his VWvan on it and does 2500 litres a year on deliveries. Proper mileage test
The only down side I really had to deal with was changing the fuel pipes on my Maverick. Got some nice bio proof ones and did front to back. Fixed corroded pipes all in one .

As I am now beginning to suspect my pump (Zexel) for my performance issues, (have already swapped the CKP and Maf from off road Mav) with a small improvement but not enough, and running my Maf and CKP on the off road Mav made little difference to it, so rang Diesel Bob, two problems, 1 he does not keep one on the shelf and 2 could be £600 to repair, so now thinking I will remove the Mav pump and swap them over, lot of work but better than £600 plus no motor for a week or more, Rick

 

[makeitfit]

Would you then service up the one you're taking off ? Reason I ask is that I have a very good one sat here in reserve for my Black Pearl. You could have mine in the short term for exchange of a good one back at some time if that helps

 

[makeitfit]

Well I'm OK as I've just spent £600 on a fully fledged Bio Processor and all the gubbins that goes with it, I'm knocking up B100 at 63p a litre all in that's as viscous as Diesel and can make 200 litres a go :thumb2

Now you're talking Can I reserve 2000 please :sly I've got IBCs and a big piss off trailer :naughty

The way I understand it is anything other than Diesel has hidden over head costs...

Diesel... £1.20(ish) per litre. Readily available within a reasonable distance anywhere in the country. No running problems, and you can use as is any time of year.

Bio... £0.80(ish) per litre. Many issues, finding a good local trust worthy source is the first big hurdle, but when away from home, impossible to find on the fly. You still have to change fuel pipes. Also because of some of the chemicals used, you may need to change the pump prematurely anyway as some Bio attacks the rubbers. You can alternatively, make your own, but need to buy expensive processing gear, plus use electricity, filters and chemicals to process it, so not only needs up-front costs, plus space and source for raw materials, but it still has fairly high over heads on going. Things that need to be taken into account is, even if you purchase old oil for £0.25 per litre, you do not actually get a full litre of fuel from this. You also need to pay for the unusable waste to be disposed of properly, which I guess is why it is relatively expensive, compared to new Veg oil.

Veg... £0.65(ish) per litre. Like diesel, readily available, and can be used as is, or mixed with Diesel, depending on time of year. Puts premature wear on your Pump.

Now based on rough figures... I do 12K miles per year. Lets say the T2 does 30MPG (Open to debate, but will do for comparison), that is 400Gallons of fuel, which is 1780litres.

The annual fuel cost if I run on 100%
Diesel £2136
Bio £1424 Saving £712
Veg £1157 Saving £979

Surely, in either case, the savings are sufficient to cover the cost of a fuel pump, as long as you get more than a year out of them, and there have been many people on here talking about running their T2's on Veg for several years, and I have never seen a post moaning about having to change the fuel pump.

For those of us, with no access to Bio, and no way to transport and store sufficient to make it worth while trying, Veg oil has to be a good alternative way to save a few quid, as long as you are aware of the possible hardware costs.

On a personal note, even if you don't run 100% veg all year, since most people run higher percentage in the warmer months, and less in the winter, in my case, I probably do about 50% as an average, I am still saving £480 (ish) a year, and at those mixes, I have never added any other chemicals, other than the odd shot of Redex here and there, when it is on offer in Costco, but I would do that even if I was using pure Diesel anyway. The only other cost I can see is the Fuel Filter, which I choose to change every 6K, rather than the 12K I would change it at, if I was running on Pure Diesel.

 

[makeitfit]

Agreed mate. I've been on bio for years as has my mate. Just remember the figures and smile
Luckily there is a good but not cheap Bio dude not too far away and a very cheap one in the woods where duty men dont go :naughty

 

[elty001]

I pay 1.00 per litre of bio,which comes down to 80p if I buy 200 ltrs or more.
Stick derv in if I need to but I only average about 6k milage a year.
Had new fuel lines fitted and change the filter regular and so far so good.

DPF

Just been having a read through this site, I can recommend it to all and especially the Veg burners and two stroke adders, there is even a big blue banner to this site, as an ex diesel engineer I can recommend this site and go along with all that he says, and the simple way he says it, helpfull info is the drop down to look at, Rick, http://www.dieselbob.co.uk/tips.shtml

Yes interesting site I liked the section on removing DPF's though there may be some issues if the MoT tester knew you had removed them.

If my 300C starts to have issues with the DPF I would bin them and have the software changed if I could get away with it at MoT time.

At work we have had quite a few new ML's with the new 250 engine having DPF burn off problems. I have driven quite a few ML 250 models with mpg displays over a 7,000 mile period showing 35 mpg average and thats not bad though they are a bit gutless compared to the 350 variants.

I like this, this is my kinda math :lol

Perhaps I should be the first to source a veg oil fuel pump, there must be a company around that do custom ones? :nenau

That is a very kind offer Pete, one which I may take you up on, once I prove for certain what is going on, first I will rob my shaft breaking Mav and go from there, also if I did have your pump with the view to having mine refurbed to return to you, it may just cost too much, bearing in mind I paid £300 for my current motor plus a bit of welding, I may be better off looking for a Bosch pumped TDi Rick
