Cooking oil cars?

Hi All,

I have heard of running used (filtered)cooking oil in some diesels with a slight modification.

A gentleman whose opinion I respect has told me that early 1980's VW pickups can run it straight without the modifications.

Can anyone verify this for me?

Thanks

Mike
 
I don't have first hand knowledge of it but there is plenty of info available on it,most people that are doing it,seem to be doing it with Volkswagon diesels but any diesel should run on it at least in warm weather,I'd be leary of it in cold weather.I do know on a few of the diesel truck forums,there's guys burning used motor oil in diesel pickups to get rid of it,not on a regular basis but after an oil change they get rid of it by putting it in their fuel tank a little at a time.
 
Here's a rally car , a regular at many rallies like our Rally new York. It has a slight aroma of a fast food place - that's why we call it the McDonald's car !!

www.greasecar.com has all the info.

Ive heard of people doing this in old land rovers and old volvos. Not sure I'd want to try it in a new high performance diesel engine.

Apparently the best method is to take pre used cooking oil and take it through s filtering and treatment process, but I have heard of people mixing fresh cooking oil with regular diesel and using it in old land rovers.

I have no idea what the long term effects of this are however!
 
I see these on the highways all the time. I always know they are there, because I think my motorcycle is burning up. Then I realize I smell a car, not my bike a few cars ahead of me.

It's called biodiesel. Here is a short informative site on how to make your own:

No it's not, not the way the OP originally described it.

There are three ways to use regular veggie oil in any diesel engine:

- Use it straight after filtering and dewatering. This requires modifications to the vehicle, mostly to start and end on regular diesel fuel and to heat the veggie oil to a higher temp so that it will flow and atomize in the engine. These modifications are mostly vehicle-specific although some of the hardware can be used on other vehicles. This is what the OP is referring to in his original post. To make it clear: veggie oil is not biodiesel.

- Biodiesel: transforms the veggie oil into biodesiel via a chemical process (transterfication (sp)). Can be used in any diesel engine except in very cold climates; bio will clean your fuel system out, so there's higher maintenance for replacing fuel filters as the bio washes out fuel system garbage. Most OEM warranties will only warrantee bio use up to B5 (i.e. 5% bio, 95% diesel) although some go to 25%. Bio is a very good diesel fuel lubricity additive, see the diesel fuel lubricity study over at thedieselplace.com site for more info on this. If you can get it, you should use it in your diesel; however plan to replace fuel filters for a while as the bio cleans out your fuel system.

- Mixing straight veggie and diesel; not recommended, don't do it.

And by the way, that JourneytoForever process is a known flawed process, don't use it to make bio; see the various and numerous bio forums for ways to make bio, GirlMark is a good source.
