I run mine 50/50 veg and diesel in warmer conditions than the present and it runs beautifully.

Could get too thick in these temperatures. I'd run a 25v/75d mix in the winter and otherwise 50/50. Although to be fair the simple P38 diesel engine could probably run a higher percentage of veg oil. Dunno if there's a suitable solvent to add to stop the system gumming up with veg oil varnish. If your lifter pump is weak any amount of veg oil might tip the balance towards difficult starting.

I've noticed vegetable oil prices have started to come down - perhaps the older diesels that can run it are starting to become rare!

It may well knacker your lift pump.

don't put neat veg oil in there are too many additives processed into the oil, it will bugger up pump and injectors, do it properly and process the oil, add hibernia(stops the oil from waxing creating blockages) when temps go below 5c and you will have no probs running 100% in winter, i have done this for 8 years now.German engines especially the mercs will run well on bio diesel as the seals are strong enough,don't put it in a ford they don't like it at all. not sure but its just a thought Ive had that its why there is not more bio diesel in the forecourt pumps because lucks pumps cant handle any more. watch out for bacteria in the tank ive just had this problem pain in the arse to clean out whole system.

lucas pumps in fords bloody spell check thing

May sound daft to some but can sunflower oil be used also where can you get hibernia and also when you state process do you just mix the oil and hibernia together if I was to do it I would use new veg oil! Ive fitted a new fip and alway been worried what damage neat veg oil would do so I have stayed well clear

So could you please explain how you do it 'the hammer'

matt1987
if you are using the methanol method once you have washed the oil wet or dry washing it needs to be heated up again to add the hibernia you do not need to wash it again so you don't have to go through the slowest part of the process. i get all my chemicals from trinity research in lymm they are on the bay and deliver/post. i dont use new veg oil too expensive by the time the chemicals/electric etc have been used to make it. the only oil that i have not had a "good yield" is what used to be called p600 as used in chippies solid fat like lard.UK Biofuel Systems T200 BioDiesel WVO Processor Reactor | eBay. this is similar to the machine i use i got the cost of buying his within 6 months so don't be put off with the price, hardest part is finding waste oil as a lot of people do it now, plus china pay top money for waste oil so a lot is being sent over pm me your email address and i can send instructions it looks difficult but as anything else once you've done it a couple times.

I decided against it in the end because someone on here reckoned his lift pump only lasted a year using svo.

Biodiesel might be worth a go if you can find a cheap source of waste oil.

Central heating oil doesn't have much tax on it ... although it does have a chemical marker, I'm told.

It will also knacker your injection pump up.

This is what I heard too. I think its OK to put diesel in most central heating boilers but not the other way around.

Strange. Wonder if that's the nature of the marker chemical they put in? I'll look into it one day.

The "Brigade"boys do it in Northern Ireland, close to the border on a massive scale. They use acids & god knows what to remove the dye. Google "Fuel laundering"-the U.K. & Ireland are losing millions in tax revenues due to it. It's estimated that the majority of diesel sold at garages close to the border is laundered !!
I can't see the mechanical problems with Agri diesel other than getting waved into a checkpoint and getting your tank dipped by the Revenue

Agri diesel is exactly the same as normal diesel except for the dye, it runs common rail tractor engine so it will work fine in any diesel car.

Central heating oil in the Uk is kerosene, not diesel. Industrial central heating plant uses 22 seconds Redwood #1 which is near enough the same as diesel, but like agri it's dyed

I run mine on veg oil and petrol most weeks

I cover 400 miles each week and run the tank from full to empty in 5 days

Have no issues running on veg oil

Also egr or no egr will make no difference - mines blocked off with a 1p coin anyway

How much petrol to veg do you run?

Correct, neat Kerosene (Paraffin) will knacker your pump up big time. It is not oily enough and wears the internals away.

I have been running my p38 diesel on a 50/50% SVO mix for about 18 months now without any serious problems. Once or twice the veg oil has dropped straight to the bottom of the fuel tank causing starting problems. Other than that the engine runs well. Actually sounds better. I buy veg oil at 90p/L in 20L kegs from Costco. The savings soon build up.
A lot of the BMW forums recommend using an inline solid state pump like a Facet if you use more than 50% veg oil.
