Vegtable/Cooking oil, who runs it? Any Advice?

[tjolliffe]

Hi all, I want to run my 200tdi engine on Vegtable oil or cooking oil. Does anyone do this, what do you use, vegtable oil or cooking oil? What % mix should I use? Also whats the law surrounding use of it?
Cheers

JUST SUCK IT AND SEE MATE, you will get that many different opinions on here your headwill explode, start at 50/50 and mix more veg oil every tank till it ticks over rough then back off a bit, by the sumer it COULD manage 100% veg oil, mine used to but that does vary from engine to engine somehow.
best thing to do is sell it buy a v8 and gas it, much better!
loads of nice noise and affordable to run. :lol: :lol:

True, at the moment the 3.9 V8 costs as much to run on LPG as the TDI does and I've had so much grief with running Biodeisel that I've given up with it.

You have to watch the price though, some LPG stations have put the price up 20p in the last few months, in line with petrol, but as a percentage rise that represents 50% increase :shock:

This time of year run at 50/50 mix...in warmer weather upto 100& veg oil should be fine.
Buy Rapeseed Oil from supermarkets to begin.
Your fuel filter will probably clog after 1-3k miles as oil cleans all the crap out...carry a spare filter with you  ;)  unless you are RRB then carry 5!  :lol: (Sorry RRB  :oops: 8-[)
Make sure your glow plugs are working too as they will be needed in cold weather.
Enjoy cheaper motoring  :dance:

All  these V8 owners seem to forget the fact that you have to pay allot of money to enjoy the cheaper fuel...tdi's you just enjoy the saving from the first drop of veg oil  :dance:
V8's are good for  :-k I have no idea  :lol:
Coat...........byeeeeeee :-'

hi, if you buy fresh oil from a shop. what do you have to do before you put it in the tank, just mix it? or is there something we are missing?  :-k, i really want to use this stuff, do i just pour it in, with there still being fuel in the tank?

I've run a V8 on gas and a TDI on 50% veg oil and I know which is better to run on and off road. A V8 sounds sweet and is more responsive when you boot it but the 200 TDI just pulls and pulls off road and isn't daunted by hills.

Been running mine on a twin tank system from diesel veg and run 100% veg oil all year round with a diesel start up tank. done around 8000miles so far so has more than paid for the kit. Im now looking at settling and filtering waist veg oil to run even cheaper.

what no one seems to mention is the fact that the veg oil molecules are 10 times the size of a diesel molecule and basically act as an abrasive to you fuel pump and injectors, dramatically shortenning the life of them.
though the savings made over 30k miles might offset the cost of rebuilding the fuel system.

as for the legality of it, if you dont pay the road fuel duty you can get your vehicle impounded and crushed, and a huge fine if you get caught
paying the duty is a matter of filling out a form and sending payment. no one can really check how much veg oil you use, compared to what you tell them ;)

You are legally allowed to produce & use 2500litres of biodiesel before you have to declare it & inform HMRC.
As for the pump & injectors....most of them upto 300tdi probably need replacing or reconditioning anyway  :lol:  Its the seal that go & I have had my pump & injectors reconditioned for veg oil use  :D

where did you get that info? i cant find it anywhere on the HMRC website.
looking through this link it looks like you have to pay duty on anything you produce/use

the 2.500litre thing came in around october 2007 might have been earlier, i suspect site out of date, you are suppose to keep a record. more info on a veg forum that the name escapes me. but i will track down .  some info on this site . www.vow2.co.uk

if you heat veg the molecules you speak of are ok, but between 70 and 90 degrees C. i run twin tank also.  start up on derv until warm then switch over i switch back about 3 miles away from home so i dont leave much veg in the pump ready for the next day start

hot engine, hot veg appears to be working fine ive nearly clocked 4k on it.

issues ive seen is when you use exsiting tank the veg cleans all the derv crud out the tank and puts it in your fuel filter, some guy was doing a new filter every week.  ive not yet changed one on mine but i do carry one. other issue is cold morning they struggle to start if too much veg in the system

also lots of debates on heaters to use i use a glow plug inline type thing,www.vow2.co.uk
 has a thermostate in it ,  you can get coolant ones etc etc, i also have a change over valve.   all cost me about 140 quid and its payed for its self. 

Ive also got a 200tdi defender and wouldnt run it on there, purly for the fact i use the 200tdi disco most days and the defender gets used for offroading , weekend drives and to work now and again,   veg doesnt seem to like to sit around outside
