Can I Run My Car On Waste Vegetable Oil

[Cybercabz]

i have a mercedes cdi 200 diesel year 2005 engine 2.2
am i able to filter waste vegetable oil from a chippy so there are no bits in it and then pour it in to the tank of my car to use for fuel,or would i need to add something to the oil first to mix it with something before poring it in.
Are there any consequnces or bad things about using it.
Is it a simple task to collect oil from my chippy and convert it for use for fuel

First consequence is likely the cost of a new engine.

There is a lot more to it than just putting it through a sieve.

the chippy are likely to already have someone who collects their oil, Bart and Homer discovered this when they wanted to make a fortune out of grease.

Do you park the car in the back lard ?

I ran my VW camper on used chip oil, I used to put 1 gallon of diesel in and then fill it up with chip oil, from outside it stank like a chip shop, it ran with no problems at all. I used to buy my oil for 37p per litre, already cleaned.

i have heard one of the large fast food companies run all there lorries on it, as said though not a straight forward process.

I don't know about chip oil, but I knew someone who ran their diesel car on kerosene, for well over a year, with no problems.
He even asked the guy from where he bought it from, if it would be safe to do so and the guy told him he needed to add approx 10% by volume of engine oil - this was to lubricate the valve seats (or something along them lines).
I think it worked out he was paying less than half of what he normally paid.

I believe that older diesel engines can cope with it, but newer ones are at risk of damage.

Straight Vegetable Oil (known as SVO here in the U.S.) is not recommended for long term use by all diesel engine manufacturers here. A number of problems occur, including fairly rapid carbon build up within the engine. Additionally, the viscocity of SVO is different enough that the spray pattern of the injectors system is enough to produce a rough running engine.

Kerosene, on the other hand can be modified fairly easy... most folks I know use Stanadyne lubricity additive and 100 to 1 Penzoil outboard engine oil (or any other 2 stroke engine oil) as an additive to get the SCAR number (roughly translated this is the number related to wear produced by friction) down to an acceptable 225 or so (untreated kerosene comes in about 600 or above). Kerosene runs hotter than diesel so one would expect less performance and higher engine deposits. Here, kerosene is about 1/2 the price of # 1 diesel due to there being no "road tax" on kerosene since its classified as a home heating fuel...
