Veggie oil - am I an idiot?

The danger is it will clog up your injectors. There are quite a lot of posts around this theme and the concensus is don't do it. If I remember rightly there's a post on this somewhere from ChearlesY, and he's good at explaining the technical stuff. Think about the small amount of money you're saving as against the cost of putting it right if it goes wrong. No way I'd stick it in mine, although as I say it seems happy on 50% bio-d - runs better in fact. The TD5 is a very different engine from the TDi's.

Hiya thanks for the reply

Well we both have the same symptoms so im happy, everything you have stated is exactly the same as mine, I have wound my turbo and fuel pump up, (also fitted a turbo gauge so as to know im not gonna blow a head or melt a piston) I found since the tune up the low end idling improved and the pull away in first is phenominal! The issue regarding the feeling of lack of power just under 2000 revs still exists if driven gently! However if i give it then its just not there at all! Regarding fuel filters my first change was 500 miles and thereafter im looking at once a month, but do carry a spare just in case!! My 80 percent is more of a guess! as i get oil every two weeks and filter over twelve days, now week one will be a quarter tank of diesel to three quarters oil, week two i will add only oil! and then start over again, if this makes sence?? I have also noticed that the engine oil seems to stay cleaner and not smell so bad which must be a plus point! Anyway great to hear from ya and that we are both getting the same results, it makes me much happier, im thinking (if its ok with you???) That i will post them in the veg oil thread that you started so as other people can look and gain a better understanding/insight of what is going on!

But again thanks for the coms and keep burning the oil, its great!

Have a good one................Jethro

Hi,

I was running 100% for about 500 miles. I then got a power issue - juddery at low revs and loss of top speed. This felt like fuel starvation - I changed the filter and I haven't had an issue since. Lots of people say you need to change filters after 500 to 1000 miles so this is normal - the thick veg oil lifts all the crap out of your tank. I certainly saw this when I used an old jerry can I usually use for red - loads of rubbish came out with the veg oil.


I ran another 600 miles or so at 100%, but I have been using diesel for a couple of weeks because I haven't got round to sorting out my tank and filter to get some more filtered oil ready. I am not doing huge miles at the moment.

It is smokey at start up for a few hundred yards then everything is fine. I make sure I don't rev too much when it is cold. There can be an issue with unburnt veg oil getting past the rings and 'gumming up the engine.' I though this was an urban myth, but I had a local LR independent confirm that they have seen this happen. I spilt some oil on my paintwork and it went really gummy and was a bugger to get off. i wouldn't want this stuff going anywhere it isn't supposed to be inside the engine.


I guess I am runnning more of a risk at 100% than at 80%.

On 100% veg it is sometimes a little odd at low revs - it can idle quite high and sometimes the engine 'hunts' a little when idling - but no real problems once it is moving.

I suggest you try changing the fuel filter if you haven't already.

Cheers

what's wrong with palm oil (other than the environmental side of it)?

oh, and you can tell if a SVO has anti foaming agent, because if it doesn't then it has a calorific value of about 900 per 100 ml and if it does then it's down to about 816.

It gets very thick when cold and therefore gels. I went out to loads of vehicles that were not starting after putting bio fuel in over winter. After making a few enquiries it turned out that suppliers were 'palming' (scuse the pun) palm oil off as being vege oil. My blowtorch's never had so much use.



If you are being given WVO in unmarked containers you don't know wether they have anti-foaming agents. Most oils used in chippies and kebeb shops etc DO have anti-foaming agents in em.

Does this also apply to using alterative fuels in a petrol engine or have we to pay the tax??

I am using an oil with anti-foaming agent. I have searched far and wide for evidence that this does harm, but I can't find any. Mine contains E900 Dimethyl Polysiloxane which seems to be a common anti-foamer in foodstuffs including chicken nuggets and Diet Pepsi. I think you are going to find this in most oils used for commercial catering.

If anyone has seen any evidence that anti-foamers do harm please post it here. For the meantime I am carrying on being an idiot...
