Veggie Oil run cars

[omega3000]

I hear one or two owners on here using veggie oil to run their cars on , my question is what car is suitable for this  Im presuming the oil is not sold commercially , so do you go round the local fish and chip shops then take it home and filter it or just chuck it straight in the tank

Little bit more to it than just that

most modern diesels will run on some oil in one form or another without any modifications,i know a disco diesel will run on veg oil but the fuel filter needs changing and i think you have to turn the fuel pump up....but the problem comes in cold weather as the oil starts to thicken so you need 2 tanks and some form of heater,as for used oil i think you would need too strain it before use and you will smell like a chip shop,and i think there is a limit as too how many miles/litres that can be used set out by the tax man

Interesting info on that site and answered one of my questions 

[quote]How much does a conversion cost?
An Elsbett "one tank" conversion, including the price of the kit and its installation, generally costs around £1200 [/quote]

might as well buy a petrol and pay for a gas converson

Or an indian takeaway 

And a couple a litres of oil in the shopping trolly for a top up 

might as well buy a petrol and pay for a gas converson

But petrol is going to run out soon and keeps going up

Modern diesel engines mostly wont run on straight veggie oil,they need biodiesel which can be made from veggie oil.
Older type diesels are often fine to run on veggie oil,particularily those which have a Bosch pump.
Cavalier (Isuzu) engines are great as are Peugeot xud,old Merc 190,s and lots of others.
The oil can be bought (usually unfiltered) commercially for around 50p per litre,or you can knock on doors of local restaurants etc. and try to get it free or cheap. Ime chip shops,kebab shops etc arent much use as the quality of the oils is very poor - full of animal fat - and takes forever to filter.
You need to have some system of filtering the oil.The simplest method is "sock filters" - which come in various grades. Typically from 100 microns down to 5 microns,so the oil can be filtered in stages.
Im fairly new to it,but many people speak about dewatering the oil.I dont know much about this yet,but the oil I currently use is very high quality and doesnt seem to need anything more than running through a filter to remove any largish particles.
In cold weather the oil can be too thick and cause difficult starting,rough running,and premaure pump failure.There are various answers to this,the simplest being to mix it with anything up to 50% diesel.
This partially negates the point of doing it imo as its relatively expensive.The best method ime is to mix 10- 15% petrol with the oil (believe it or not) which keeps the oil thin and makes the engine pretty pokey as well.

P.S The limit set by the taxman is 2500 litres per year of personal use.

My brother has run his Pug 306 for years ONLY on homemade bio. It isn't free but not far off if you go about it the right way. You need a bit of space, lots of storage containers and a bit of patience - oh and a supply of oil and a "still"

Q. How does the taxman know how much you have used? What a daft rule. Anyway I guess that would be about 20k miles!

Thanks for that link albs and will have a read through it tomorrow  I did spot the old pugs and citroens being used in the link martian posted .

How does the tax man know how much your using 

[albitz]

You keep a record of what oil you collect,where you got it from etc.Then in the unlikely event the taxman comes knocking,you show him. Tbh its unlikely an individual motorist is going to exceed the limit,so as long as your not selling it on for profit etc. I cant see any problems arising. My Cav does 40 mpg so 2500 litres would be (as Varche suggested) at least 20,000 miles p.a. I do around 6,000 miles p.a. in it.

I'm going to start running my Merc on veggie oil from Costco when the weather warms up. It'll be 80% oil/20% diesel and I'm sure she'll be fine.  I used to do it with a Rover 218 diesel.

Sounds good or like albs said  10- 15% petrol with the oil

well that intresting as know of five companies that run,focuses,octavias and volvo's,peugets all under a year all run on veg oil with no modifications and all run with no problems...not sure what it does to the injectors etc,come to think of it not sure what it would do too the warranty either

Iirc, you thin it out with ethnol
