Is anyone on here familiar with running diesels on vegetable oil? I will be getting a peugeot 309 with the 1.8 turbo diesel engine soon and I am looking into this as a possibility to save on running costs. Am I right in thinking that if the car has the lucas pump veg oil is a big no no?
Thanks

Before you think further look into the cost of veg oil. You will find its only a couple of pence cheaper than pump diesel so not viable - at present. I've run diesels on veg oil for probably 15 years yet now I don't bother as no real savings. Used veg oil is horrible so don't even think about "free fuel" using that. First it's difficult to find (I had to jump though legal hoops to get a regular supply from a school) and second it's so contaminated with burnt food and water that only a small percentage that you collect is useable. Best leave used veg oil to those who make proper bio diesel although that is no longer viable process as long gone are the days of getting the used oil for nothing.

Yeah, we're getting it at well below a quid a litre, for properly cleaned (filtered and centrifuged) stuff. Used, but perfect to put in your tank.
One thing I would say is that a switchable system is best - start and stop on diseasle. Veg oil (especially ropy used stuff) polymerises for a pastime, and when it has, nothing will shift it. That means it can curse word your pump, or injectors, or most often stick your rings up causing runaway. Which is scary. However, if you can stop the runaway in time (co2 extinguishers do the trick) then a prodigious amount of steam going down the spout when you restart will fix it! Least ways, it did for our big cummins. Water vapour (or washer fluid for the added ethanol) in the intake air is a really good idea on anything that you plan to run veg oil in for a long time.

I can get it below pump diesel price. I was thinking of running a 50/50 mix to save the expense of switchable tanks etc. Just waiting for the car to arrive tomorrow so I can see what pump its running first as google suggest lucas pumps are not up to it

I ran a Pug 205 diesel with Lucas CAV pump on 50:50 mix for thousands of miles. In the end a seal failed on the pump but cost less than £1 for the part to repair. NEVER just pour oil into the tank. It will settle at the bottom so the pump diesel is on top. If you do this in a clear bottle you will see that they don't mix unless shaken so the same happens in the tank. I always mix in a 20/25 litre drum and then use a caravan water pump to transfer into the vehicle tank. I did have a proper diesel pump but was no better. Don't assume that the pressure of diesel from pump will fully mix either. Neighbour did and we ended up having to drain his tank as it wouldn't start due to pump just sucking up neat veg oil that was too viscous for the engine to run in cold weather.
Cheapest I can get fresh veg oil around here (Stoke-on-Trent) is 99p litre. I used to buy in 20 litre drums from cash and carry's but no cheaper than 1 litre bottles from supermarkets - just more convenient.
I'm hoping fresh veg oil comes down in price as my current Discovery (300TDi) will happily run on it - however my Skoda 1.4TDi won't !

So once it has been shaken to be mixed it won't separate again?

Never had an issue mixing it TBH, perhaps my driving style mixes it better though i do blend my fuel (lucas pump) 70% doosil 25% SVO 4% stale petrol and 1% 2 stroke oil, makes my old P100 hum like a sewing machine and run sooo much better, on a bosch pump i run 95% SVO 5% petrol, just to get it to flow a bit better, my 106 loves SVO but still prefers a wee drop of 2stroke, makes cold starts easyer. Tesco have been selling 10L for £8 for the last 2 months and macro ect are cheaper

If you can buy it from a 'cash and carry' or Costco its under £15 for 20Litres so way cheaper than derv at the pump.

It's certainly not 'a couple of pence cheaper than diesel', unless you're running a comparison against 500ml bottles from the supermarket. 20l drums can be had for £0.70 litre.

OK - I accept that others can get veg oil cheaper than me I'm PRO running on veg oil and it's price that had stopped me doing after many years. At one time I was paying 39p litre when pump diesel was just under £1 so the savings were quite substantial.

I went round the local small cafes and snack vans asking if they had any waste oil, I used to get 100l a week free just had to provide them with a drum to put it in.

For a while now businesses who produce such waste have to abide by strict rules regarding disposal. There are exemption for private individuals who collect but business still has to record their details to avoid falling foul of the environmental bodies if they get inspected. I think the law change in 2004.

About 3 years now, I regularly ended up with that much of the heavy ends after I had settled it out that I swapped 3l oil for 1l Bio D to get rid of it. I think the places I went to were all keen to keep the builders coming in who were spending a fortune on bacon butties A couple of the cafes told me how much hassle they had getting rid of it! If you are up Humberside way there was a company doing IBC's of new oil for about 70ppl when the shop prices for oil were over a £1 on special

I have ran a Citreon AX and VW Golf both on Aldi's finest. Poured straignt into the tank with no issues.
I then had a Toyota Townace and decided to use waste oil, bit of a faff but I filtered through a fabric Primark bag to get rid of the big stuff, then a jay cloth ...then a face mask (fibre one that goes over nose and mouth) then let it settle for a week and no issues what so ever.
Oh and yes I really am that tight !!!

Maybe 75% of what I collected was unsuitable and had to be dumped. Also in winter, when temperature dropped, even the filtered oil turned very thick and almost like jelly.

Got the new car home last night and it's got a Lucas pump. Google says vegetable oil can't be put through a Lucas pump so looks like I'm sticking to pump diesel
