Smoking badly on veggie oil

Decided to take the plunge and put 20L of veggie oil into my Disco 300TDi. There was very little diesel left in the tank and I took her for a 10 mile drive with no issues. Went to start her up today and my battery won't crank over quicke enough to start so jumped the old girl. Finally got her going and after she was smoking very heavily for about 10 mins before I switched off the engine. The smoke is white / grey. Any ideas? If I drove her like that I would risk getting pulled. Had no smoking issues whilst running on DERV.

Oh i am not sure about that but try topping up with £20 worth of diesel, it will dilute the veggie oil. I have been reading alot about it on here and they reckon on a 50/50 mix in summer and a lesser mix in the colder months say 30/70. good luck.

Second that. Too much veg oil in one hit. Get some derv in there and all will be well.

70/30 mix. Stick 5lites of petrol in it to thin the oil down for starting.

you should be mixing it with diesel as the veggie is a bit thick to run neat.you will need to have a good battery when running on veggie and maybe an inline heater to thin out the oil.

as above i managed 100%veg in our summer when we got to 19 degrees, but anything lower than 14ish and the old girl struggled, i then ran her on 50/50 and she was fine, not run her on veg since cambelt chage but will prob be down to 70/30, but i am going to try 5% petrol to veg oil to see what shes like.

I found that my old 300tdi ran fine on 70% Rapeseed oil but didn't like running on oil with anti-foaming agents in it. If it had anti-foaming agents in it, it would smoke and stutter on start up and until it had warmed up.

I know it's sounds like a daft question but isn't the price of veg oil currently the same price of diesel at the pumps ????

Unless its used veg oil

Its about £20 for 20L whereas derv is going to cost you £30 for your 20L

We're s the best place at mo to buy

I got mine at MaKro - £39.96 for 40L

If you are going to try swo (straight veg oil) mixed with derv in some proportion,try and get rapeseed oil if you can ,it is thinner than Gm soya

tesco nearly always have an offer on that is 2x5 litre bottles for a tenner

Here in France you can get sunfloweroil for +/-60 cent per liter in Aldi and Lidl. Its kind of fun to to go there, buy a couple of boxes and fill up straight in front of the shop ;-).

CIRRUS:
If you intend to become "veggie-fundamentalist" you MUST fit a inline heater to heat that up this soup, otherwise you risk to screw up the battery with long ignition time.

I ad sometimes a bit 2 stroke oil to clean up the mess left (chemically the same like "tune-up). I only use a mix of 50:50 mix without torturing the engine above 3500 rpm. This is now going on since 2 years & over 40.000 km without any hassle. Once I had to clean the tank. Ah yes, its the good old 4cyl. in 200Tdi..., drinking everything else as well something between 6,5 to 8 liter per 100 km.

I now have a 50/50 mix and she runs fine on that. I am having the battery tested this week and deep charged as it is struggling to turn over quickly enough. Have to say though that not sure it's worth the saving to be made - 20 litres DERV & 20 litres SVO costs me £48.60 instead of £57.20 on DERV alone.

17.20 per tank @ 80 litres

depends how much you use it, i go through 1.5 to 2 tanks a month usually, so

34.40 x 12 = 412.80...so pays for tax and other odds and sods..

worth it to me, i would save more than that aswell as i use more veg then derv.

yh i got some of that the other day

Mine doesn't like too much sunflower oil. It can drive abit jerky if it's not mixed with diesel. Is fine on motorway and higher rpm.

I am like that in the morning too..

When we had our old 200TDi ...

we used to put a cetane improver in perked it up great ...

just remember to change the fuel filter after a 100 or so miles, SVO will clean out you fuel pipes very well ...
