Can I just pour cooking oil from the supermarket into my diesel tank?

Question

Renault Turbo diesel?

Answer 1

"can" implies a physical ability. YES, I'm sure you are physically capable of doing that, but SHOULD you? Probably not. Unless you're up for Dummy Of The Year award, then go ahead.

Answer 2

No,You have to have the injectors modified,Other wise engine knackered.

Answer 3

Yea I think you can but you have to add an accelerant i.e diesel

Answer 4

NOO!!! you cant!! your engine MUST be modifed to do that!!!!  its like putting pretrol into a diesel car.. ie total ruination of the engine!!

Answer 5

Go for it, vroom vroom!!!

Answer 6

better off in a chip pan

Answer 7

Yes, you can. BUT there are certain things to look out for. 1st--the answer that it must be used is not right.  if it is used it must be filtered very very very well.  2nd--the oil will gel if at a lower temperature (colder weather) and that will clog up your fuel lines and injectors.  So there is no simple yes or no answer, you must do the research try the site www.thedieselplace.com  best site out there for diesel knowledge.  EVEN the newer engines are approved to run on biodiesel which is made from veggie oil--really cool technology when you think about it.

Answer 8

If you have a Bosch diesel pump, then yes yo can get away with this in hot weather. Now - in October, then it's too thick to use without pre heating it as it's too thick at autumn temperatures. Proper SVO conversions have a second tank and heating coil to provide the heat.

If you have a Lucas pump, then it's a no-go at any time of the year. However, if it's a throwaway car then you've nothing to lose.

You will, of course, be paying the duty won't you ;)

Answer 9

My mates car runs on asda cooking oil i couldnt believe it myself until i saw it for myself he just pours it in and is away

Answer 10

Legally your not meant to (cos you are not paying duty on it)

But most diesels will run on cooking oil in the summer months,

In the winter you should mix at least 50/50 with normal diesel or you can buy an in-line  fuel heater (quite a few on e-bay)

Dont use used oil unless you filter it.

Older cars have natural rubber fuel lines and they can break down over time if used with cooking oil, more modern cars (1995 or newer) have synthetic fuel lines and these are ok.

your car will burn cleaner with cooking oil than with regular Diesel, more power(slightly) and more mpg.

BUT...........

It will smell like a chip shop, alright whilst cruising along but you might want to switch your engine off at Traffic lights ect.

if your not sure try using "Bio Diesel" to start with http://www.enfuels.co.uk     its made from cooking oil and you can use it all year round with no mods at all and its only 92p a litre

Answer 11

it has to be used oil

Answer 12

If you're talking about used oil  you would need to filter the oil first.  Any food particles can clog fuel injectors.

The oil should probably mix well with the diesel fuel.  You might try mixing it about 50:50 in a bucket or can.  If that mixes well, you might then add the mixture to your fuel tank......with the tank at least half full of diesel fuel.  Then try to up the amount of cooking oil you're adding.  

Plain cooking oil might be too viscous (thick) for your engine....especially in winter.  Thinning it with diesel fuel should help.

Answer 13

yes you can , the car may not go , but you can

Answer 14

If you try this please report back to us on how many miles you get.  Im not joking.  I use old cars as im skinty so i would like to know.

Answer 15

depends on the year your car was made

Answer 16

no the oil is too heavy and must be treated with other chemicals to lighten it.

Answer 17

If this catches on so will the increase in prices for Sunflower, Olive & Vegetable oil....great!!

Answer 18

yes you can but your injectors will clog every now and then and you cant get done for it because you pay tax on oil

Answer 19

No, it won't work

Answer 20

Probably wouldn't go down too well in a modern turbo Diesel, particularly a high-pressure system, but in an old Merc or Land Rover, yes, it works. You'd need to add some petrol or paraffin to it in winter to stop it solidifying though.

But to answer your question, I wouldn't put it in a modern Renault.

Answer 21

It is a free world - you can do what you want

HOWEVER, you would do less damage to your engine if you poured raw sewerage into the tank.

So, if you want to damage your engine - go ahead

Answer 22

Mix it with 3 parts Balsamic vingear 2 parts parsley butter and a teaspoon of mustard and you will be good to go.

Answer 23

if you use a funnel, yes. but it wont do any good.

Answer 24

I wouldn't. The glycerine needs to be removed with methanol and lye before you use it as fuel. Besides, in the U.S, oil from the store costs more than diesel per gallon.

Answer 25

no has to be used. think top gear or another motor program did a program on it. stopped off at chippys to use their waste oil that had been used.

they used a normal very old diesel engine for it ho. not sure what it would do to a newer engine tho.

Answer 26

Depends on the year.

1987 oil is the best.

Only kidding.

If it's an older car, then yes.
