Running a car on cooking oil?

Featured Replies

Hi all,

Read about this in the paper last night and was just wondering does this not damage your engine in the long run.

Good few topics on here about this Davy.

From what i remember, PD engines arn't too good with this type of thing.

But i'll add my usual disclaimer...

I'm usually wrong. :D

Thats what I thought about the pd engines, noticed some guy in the paper filling up his tdi alhambra

I'm not 100% sure what the score is,

i think it's 50/50 with some saying it's fine, others saying steer clear.

Until anythings proven, i'll stick with the real stuff. :)

I would too stick with the normal stuff, had my dad joking about sticking it in my car yesterday with the crsip and dry!

Does low fat stuff make your car lighter ?? :D

A guy at work uses veggie oil all the time in his Frontera - it's got the 2.5-litre BMW TD lump with fuel pre-heater fitted. He's never had any issues at all.

I wouldn't try it on mine though...

My dad has been sticking about a 50/50 mixture in his Sharan for quite some time now and not had any problems.

Its a T reg (i think) so not sure its a PD engine... just know its a 1.9tdi 110.

But best to stear clear with newer engines for now.

i had r reg seat ibiza tdi some time ago and ran that on cooking oil for about 30k,never had any problems. did stink though but for the amount of money i saved it was worth it!

Do they really smell that much ?

What sort of smell?

I used to be able to smell it when i got out of my car, it smelt vaguely like a chip shop. nothing too over powering

my uncle runs his 406 hdi on it and i cant smell it.....:confused:

im not trying it till proven otherwise though :thumbup:

stand behind his car and get him to rev it it, if you cant smell it your nose is broke:rofl:

Same here, not worth the risk.

Not sure how it would affect a remapped car either.

Alternatively... you could buy a proper kit and get it fitted... they are available for the pd130 engine:

Heres the site... click on "PKW/Kleinbusse/Cars/Vans/ Personenwagens/Busjes/Vans" then it will list all cars makes.

It's fine for old mechanical injection pump engines. Don't try it with HP electronic injection, common rail or unit injector engines.

I think it also clogs up your fuel filter a lot faster?

There is an article in Volkswagen Driver mag this month about this. One of the mag's contributors has converted a T5 TDI to run on it. I think the company that did the conversion is called DieselVeg or similar (?)

From what I remember (I don't have the mag to hand and I had consumed a beer or two when I read it!) the PD engines need a Diesel feed until the car reaches operating temperature as the 'fat' is too thick when the engine is cold and will bugger up the PD injectors. He ran the T5 on Tesco cooking oil which he said was the cheapest. Used cooking oil has to be properly filtered before it can be used in a PD and this takes quite a bit of work.

For anyone covering a high mileage who is seriously interested the mag can be obtained here: wwwautometrix.co.uk
