Could I run a car on waste veg oil

I used to run my old Peugeot 405's on waste oil, I just left the oil for a week to let the animal fat and food bits to sink, then decanted it off and used it!

Make sure the car has a Bosch fuel pump, Lucas/Roto aren't strong enough, and don't use neat oil in winter.

You can make bio diesel with not much effort, and you can buy preheater kits that use a glowplug to heat the oil/thin it down.

Loads of books but try this:

Well worth it, it burns better than pump diesel plus its a natural lubricant...the first diesel engines actually ran on peanut oil! :good:

Don't know about your car, depends on how old it is, but been running my 200tdi Disco on WVO, NOT, Bio, for quite a few years now. If you got the old Lucas or Bosch injector pump and not the modern, common rail injection system, PROBABLY, ok. I get my oil from local pubs and filter it down to 1 micron. In summer, when....err, warm, I can run it on a mix of 20L of oil to 2L of white spirit, now it's winter, I add 20L of normal derv as well.

Only setback is, it smells like a chippy, EVERYWHERE :lol: Last MOT, the examiner complained, it stank, but flew through emission test :yes: Think he had no sense of humour :oops:

If I were you, I would search for "your vehicle" + WVO on google and see what comes up, BEFORE you even try :hmm:

If you can use it, be ready with a few new fuel filters, as WVO scours the **** out of the tank and fuel lines for a while, then ok. Better economy and better performance can be the result

I have just bought and waiting delivery of a bio diesel processing set up, along with all the chemicals etc. The fuel quality is as good as a forecourt so I will be running it in my 2.0 td mazda 6 and the freelander td4. It can do about 100 litres at a time and only takes about an hour after you have left it too settle.

 

As for running wvo with just being filtered there is a two tank system which seems to work very well, in efffect you have a small tank in your boot of diesel to start and stop on and your main tank is wvo. It needs preheaters and things but worth the effort. Also it stops wvo sitting in your fuel line and diesel pump which is what eats them away.

 

The other option is just mix it with diesel 50.50 or what ever ration you want depending on how cold it is.

I fill up in the car parks :D get so many odd looks from people as you dump 3L bottles down the hatch

 

 

Make sure you get the ones without anti foaming agents if you buy new

I used to run my old Pug on super market sun flower oil at 70 pence a litre, it wasnt long before the price went to over a £1 a litre. :angry:

I bought a Shogun mainly because it can run on almost anything that you can put in the tank. Wast veg oil filtered to 1 micron thinned with regular unleaded gasoline when its cold, Straight veg oil from cash and carry (still less than £1 per ltr.) Acetone (nail polish remover) to boost octaine rating. Older diesels OK newer diesels fussy on fuel you may be able to introduce them to Bio slowly. Theres lots of info out there, seek and ye shall find.

All the best

sure i was reading somewhere the greedy goverment had introduce a tax on it if you produced a certain amount??

 

I believe you have to pay tax over 2500 litres, which is enough to make a big saving first and enough for most people anyway.

Of course, the day you get discovered using it is the day you started, so it's 2500 litres per year from when they find out... :)

Most modern diesels will run on biodiesel but not veg oil, most older diesels will run on either.

 

There are issues with veg oil, not least being ring gumming, caused by burning oil in a cold engine. The resolution to this is a twin tank system and heat exchanger to maintain viscosity when it gets cold!

 

There's loads of info out there, try http://www.vegetableoildiesel.co.uk, stacks of info. I've run my Pajero on WVO for a while now but you MUST ensure it's filtered well and de-watered. I'm about to start producing Bio diesel, for £400 you can get set up and be producing bio diesel for as little as 40p a litre. Won't take long to get your money back if you do significant mileage.

 

I have to laugh at those that keep saying "With the price of veg oil in the shops, it's just not worth it"! I can get oil at £1.00 a litre, that's 40p or more a litre less than diesel, and yet these are probably the same people who travel 5 miles to fill up for 2p a litre less than locally! :lol:

If you do start using it as well your car will come to a spluttering hault as the oil acts as a detergent and cleans your diesel tank and fuel lines and all this crude blocks the filters. By sounds of it normally takes 2 or 3 filter changes but after that should be all good.

 

The 2500 is a pointless figure as there is no requirement to keep records so they will never prove you have done more.
