Making Biodiesel from used chip oil

I've got a Peugeot 306 Diesel (XUD lump) non-turbo but not sure if its worth the risk :o

Would it work on just pure vegetable oil? :confused:

Yes, in summer it will run 100% although to be safe I've seen it recommended you run no more than 80%
 
Right, time for this thread to be revived :)

With the realy high Diesel prices at the moment.. I want to run my HDi on Biodiesel, not the 5 percent stuff from the pumps. Proper biodiesel thats made from new or used veg oil,

I understand that you need certain chemicals to break down the fats in the veg oil ?

You need to get the amounts spot on or you will either end up with crap biodiesel, or something useless.

You also need to wash the Biodiesel to remove the glycerin etc..

Does anybody know of a nice cheap Processing unit that I can dump my veg oil in.. add my chemicals.. flick a switch then come back in a few days time and wash the fuel ?

The cheapest I've come across at the moment is one made by " Yorkshire Green Fuels " which is £330 delivered to your door, this does what I've asked for above but makes 160 litres at a time.. which is a bit too much..

would be ideal if you can store it easily.

Check over on http://www.vegetableoildiesel.co.uk/forum/index.php

The glycerin drops out during the biodiesel process, it's the methanol you need to be sure is removed.

If you have the time, build your own processor, LOADS cheaper.

Thanks, I will sign up later :)

I've got lots of time, going to look on ebay later for some bits :D

160 litres at a time sounds great. How many litres would you have to use to break even?

No idea how long it takes to break even sorry, Main problem is getting someone to supply the used veg oil.. It probably wouldn't take me long to break even because I would get dad to stick it in the tractors , in his car, my car, sisters boyfriends truck :D , and used veg oil works out cheaper than red diesel these days..

It's like re-filling print cartridges; cheaper, but messy, and not as good for the car.

Hmm.. I don't see it like that sorry :p

Its cheaper, you can make it yourself ( unlike Ink ) and I've read that its actually better for your car :confused:

It doesn't have the lubricating abilities of real diesel, it gets into the engine oil, its anti-waxing measures are as crude as adding petrol, and the food particles (if you're using used) can't be good for the CAT.

Just look at the damage it did to Top Gear's BMW.

lol :D

Correctly made biodiesel doesn't have particles left in it, it's filtered after production and again in the engine bay. And the stuff TG used was a gash batch with methanol left in.

The anti-waxing measures are the same crude measures that have been used for the last 70-80 years.

Thanks for cleaning that one up SB118, you mean top gear either didn't mix the chemicals properly ? or put too much in ? or didn't wash a particular batch ?

Theres a guy over at the tdci forum who runs his HDi on 100% home made bio with no problems, he also runs it in a newer engined peugeot with FAP , with no problems :)

I don't mind spending a little extra on some additives to give it more lubricating properies, or to stop it freezing :)

There are a couple of ways of removing methanol, some involve recovery (for reuse), so any one of a number of things could have gone wrong.

Leaving methanol in to try and modify the fuel is generally a bad idea as methanol beats the hell out of plastic/rubber hoses & seals. As TG found out.

Biodiesel is actually a "cleaner" fuel on the basis of it strips out all the muck from your tank, fuel lines, pump and injectors. If you get a bad batch and you've got serious trouble.
