bio diesel 300 tdi

[micheal]

hi there all i was using comercialy bought bio disesl from a local supplier untill the car didnt run that well and i found 4" of setteled fat in the sdimenter after claening i reverted back to using just normal diesel i was thinking of buying some veg oil from the super market and using that would you recomend this for short journeys around town
thanks all micheal

[Snagger]

Absolutely not. On short journeys, the engine doesn't warm enough for vegoil to be a good idea. You should only use it in a warm engine.

Stick to diesel or make biodiesel. At current prices for buying SVO, it's not worth it unless you get a supply of free used oil, which is fine for making biodiesel, but no too good for running straight as it has water an fat contamination, and could easily be palm or soya oil which is bad for coking.

hi there i didnt think that it would be i used to use bio diesel but i got a couple of bad batches of the stuff the place that sld me it just pump it stright into the tank and i dont think that it was even treated in the way that it should be

Ethanol is an alternative fuel for petrol engines. bio-fuels are not
suitable for use in spark ignition engines and will damage the engine.
The two types of fuel are absolutely inter-mixable, and can be burned together.

Horses for courses really, Same ol' chestnut, my 300's on 30%svo in winter, and 50% (mixed with 10% unleaded)now. some times I only drive 2 miles. been usin' it 13 months now, done over 9,000 miles, saved a good bit, runs like a dream. Hey Ho , but wat do I know!, in the end its up to you really innit.

Hi

I used to have a TDi 300 Disco and, as I recall it, LR said it couldn't be run on Bio as the fuel system seals weren't right for it.

I now have a Def with a TDi 300 in it and am wondering if I can use Bio in it.

Any advice gratefully received.

Hi there, i have been using my own homemade bio for over a year in my defender and disco, if i make a batch that is not quite up to speck i put it in one of the tdi 300s no probs what so ever my wife drive`s the td5 2001 and it has covered over 7000 miles no probs i bought my defender for £2400, i have not been too a garage for 16 months except for an m.o.t and to blow up the tyre`s so if it blow`s up tomorrow i thing i will still be £1000 up. So don`t listen to them who say don`t use bio ..... If you know the quality of it is good use it. Willie

Interesting. Thanks.

Yes true ethanol is a petrol alternative but you should not run a car petrol engine on pure ethanol unless it has been coinverted for that fuel. The highest ethnol available that I have heard of thats commercially available is E85 and to run that you muist have a car thats able to take it, its not the engine thats the problem its some of the pipes and washers etc.

Its normal now to have up to 5% ethanol in petrol and at the that conecntration its fine.

I used to make my own bio diesel and use it at 100%. The engine (300TDI) worked great, the only problem I had was, after 3 years the injector pump started leaking. The rubbers deteriorated and I had fuel leaking into the timing belt cover. I had the fuel pump reconditioned and the seals replaced with synthetic rubber I believe the trade name is Viton.
Also to be careful of, due to the fact that the biodiesel is a solvent, it will tend to clean the fuel system and tank requiring the fuel filter to be changed more often.
Also if the fuel is not made to a high standard there is the possibility of a resin like substance collecting and restricting fuel flow this is usually also avoided by frequent fuel filter changes. I also added an transparent inline filter to the fuel line before the main fuel filter.
This I hasten to add, may have been due to the fact that I used 100% biodiesel, mixing with fossil diesel should pose no problems as long as it is not too rich a biodiesel mix. Having a mix for summer and a mix for winter is also wise.
I have a link in my signature with photos about my biodiesel manufacturing days.

HI... Buzz

I've loved reading your posts and have added a reply to one of the Malta threads where you are all discussing BIO production... it's really helped me to understand the BIO DIESEL process.

I recently bought a '92 110 Defender with a 200TDi engine (only 85k on the clock) and I've been looking into running it on Bio Diesel and called some local suppliers. Eventually I'll produce my own as the UK law states 2500 litres a year are Tax exempt and that's plenty for my purposes. Thinking of buying one of these - http://greenfuels.co.uk/product/fuelpod-2.aspx

Since you know all the Pros & Cons of Bio and what the viscosity does to the fuel pump, seals etc. and the waxing issues in cold weather etc. what should I be looking out for when I start using it?
My questions are:

1. Do I need to change the fuel line seals first?
2. What is the ideal pump for a 200TDi that will cope with Bio?
3. What's the worst fuel pump for it?
4. Is there a particular fuel filter heater that helps with the waxing issue (i've read electric ones are better than ones that use coolant)
5. How often should I be looking to change the fuel filter?
6. Is it essential to have a mix of Fossil Diesel during winter months to prevent clogging?
7. What's the best mix 50/50 - 70/30 or 80/20 ?
8. Is there a thinning agent to add to 100% BIO that will stop the waxing process and clogging?

Hope you can help as I really want to stop buying Fossil fuel :)

Thanks

hi there bud, I have been making and useing bio fuel for three years and beleave me i would not go back to mineral.

I have used it in my tdi 200 both tdi300 and my wifes tdi 5 No problems what so ever i use 100% bio,
if it is good quality and de methed properly you will minimise all your problems,about changing anything pumps/pipes/seals, dont bother your leaks will be very small and you will have pleanty of time to resolve it, (IF ITS NOT BROKE DONT FIXIT) you should have a bosh pump and they are as hard as nails.
as for buying a full made up system dont you will kick your self when it arrives and you see how easy it can be built for hafe the price.

I am a member on this site http://www.vegetableoildiesel.co.uk/ go on there and do a bit more home work.

Hi Willie,

I sent the guy a message and he asked for my email address via U2U... sent it over but haven’t heard back yet. In the meantime I’ve found these 2 processors for sale that look good (and much cheaper than the FuelPod 2). Take a look at let me know what you think:

HI Nolan, if you wont a good cheep system i have one of these i have made about 12,000 lt with no probs at all oilybits the guy there will keep you right go on ebay an put this number in the search box. 160374121088 all you need is a bench top made out of an old worktop cut out a circle so the reactor can fit through to first lip shelf underneath cut out a smaller circle with 6inches of reactor sticking though to make it all steady, then you are good to go. have a look see if this was the sort of plant you had in mind. willie

[Nolan]

Thanks Willie, looks like a good system (and cheap). I am still looking and will definitely get in touch with your guy.
In the meantime what did you think of the links I sent in the previous post? Any good?

Nolan

[BLACKBESS90]

hey nolan, forget about the heated filter, it was 9 below here last week i just use 25% derv never had any probs starting or running, the glass bowl is the way to go my man. it will give you pease of mind as well.
if you can put the plant together that is the one you want basic nothing there you don't know,( what the firk is that for.) any thing else bud give me a shout. try and get someone near you to get a look at the way they do it and adapt your own way that is the way i went.

There is not two people making it the same way every body finds a better way that suits them..............

[micheal]

hi guys after finally getting my password im back on lol
my disco is now on bio and runnning pretty good after the injectors began dribbling had them taken out and tested the guy said that a bit of muck coulod have caused two of them to dribble on the bio but as ive run the car got the engine warm and added shell vpower diesel over the last couple of weeks it seems to have got better im wondering if i should keep on adding the bio to the tank and getting some more use out of the disco on bio or weather or not to continue on dino

[BLACKBESS90]

micheal, i am not preaching bio but do you make your own if so if it is demethed properly and passes the 27/3 test is is beter than mineral you wont have any dirt from the bio, the only dirt you will have is from the deposits the mineral has left behind, so if after the bad weather you are back to using 100% bio make sure you change the fuel filter more often to catch the muck left with the mineral. willie

[micheal]

Hi there mate no I don't make it my self i buy it from
a supplier that's local to me but would it start working within 2 miles and I only put in a tenners worth off bio to half a tank of diesel and bought twenty quids worth in a drum that was clean and since then I have had what sounds to be a loud knock on the engine I can only put it down to the bio it's slightly improving over time and I've used all of my bio

[micheal]

I'm going to crawl under the disco and just check if there's any muck and crap in the sedimenter tommorow afternoon resett the tappets and maybe change the fuel filter for the second time in a week lol. I wana see if using the bio has dragge any muck from the tank it all got done a month before the bio went into the disco and the filter was only changed around two weeks ago again before the bio went into the tank il chuck in another couple of fuel treatments and see if that helps it did before and fill it up with v power diesel and then run it a few miles over the weekend. I was just wondering if using bio would drag crap out of the tank and start working within 2 miles and cause the injectors knocking or dribbling I must admit it hasn't been to bad over the last couple of weeks it has improved the more that I have run the disco but it ain't any where as near as quite as what it should be for a 300 tdi
