Title: Chip fat.... sorry biodiesel - a question?
Post by: Psychoman on June 12, 2006, 06:49:46 PM
OKay, apart from the pong of the Chippy, anyone know of any other disadvantages? Someone has started selling this locally and claims is safe for all diesel engines, but I remember some horror stories about this stuff disolving gaskets, pipes, etc... anyone had any practical experience? Cheers.

This comes up every now and then. A couple of years ago it made the news because a whole Welsh village got nicked for using it!!!

It will run in 'older' simple engines without problem, but don't even think about it in a modern common rail engine.

I seem to remember someone saying you had to 'decoke' it about every three month because it 'gums' up.

A guy at work makes the stuff,  Seems to run OK in most things oil burning.  It might pay to run some 'real' diesel though it occasionally to clean everything out.  Oh and keep checkin the fuel filter.  Home made stuff tends to have a little emmulsion in it cos it's virtually impossible to get all of the water out without really expensive equipment which is well beyond most small time producers. :wink:

The real story about the Welsh wasn't properly covered in UK papers.
They were running commecial vehicle on veg oil and selling to others.
The actual case was for VAT evasion and not fuel duty !
I've personally done probably 20,000+ miles in a variety of vehicles on new veg oil mixed with pump diesel without an problems.

I didn`t believe it personally till my mate pulled into morrisons car park on our way home (we were short on fuel) and went and bought 6 ltrs of Veg oil and poured it straight into the tank of his Peugeot 106.It got us home and he said that would do him the week :!: Usually its the filtered waste stuff form the local chippy.
  He said in winter he does the mixing it with diesel to keep it `thinnner` and the fuel filter gets changed more often.

I work for a company which deals in animal by-products (offall, fat, blood, bones etc..) which is investigating producing bio-diesel.

Since I presume this will be a mix of animal fat and diesel, I wonder if it will be labelled not suitable for vegetarians?

Incidently, tallow (animal fat) is used as a fuel source in the factory as a replacement for heavy oil, and provided it is heated and filtered, could be used as a diesel substitute in suitable engines / generators.  Even though it is classed as a waste product, we still have to pay fuel duty!

Did you know that................

The diesel engine should actually be called the veg' oil engine since that was what it was originally designed to run on.

The original engines were only later converted to run on diesel because veg' oil was too expensive as a fuel! :wink:

Not sure.  But it should be easy enough to do a web search to find out if you can.

Mate of mine used to run his Cherry on a diesel/mazola mix. He'd fill up with diesel, then as it got used, he'd top up with veg oil. When the diesel percentage got below a certain point, he'd top up with diesel again and start over. AFAIK he's still doing fine on this method.

There's a fella in Wolverhampton that runs a dieselveg conversion on his 3.1TD WJ. It's on http://http://www.dieselveg.com. Since the taxman now doesn't class veg oil as biodiesel, it doesn't attract the 27.1p/litre tax rate, but the usual 47.1p of diesel, unless you have your veg oil tested. I looked into this ages ago, and concluded it wasn't worth the hassle.

Oh, and if the taxman catches you using veg oil as fuel and you haven't paid the tax, you'll get shit on from a ludicrous height.
