TD5 BioD?

I haven't seen that one in a while, tis always one of my favorites.

On a weight basis, the energy level is 12.5% less. Since biodiesel is more dense than the diesel fuel, the energy content is only 8% less on a per gallon basis (32.9 MJ/liter compared with 36.0 MJ/liter).

Since diesel engines will inject equal volumes of fuel, diesel engine operators may see a power loss of about 8.4%. In some cases, the power loss may be even less than this because biodiesel's higher viscosity can decrease the amount of fuel that leaks past the plungers in the diesel fuel injection pump leaving more fuel to be injected."

so there.. "oomph", now defined..

Also given biodiesel is a natural lubricant it doesn't need some of the additivies of dino-diesel, and the engine runs smoother (less friction) as a result. So the actual power drop is less than the amount of energy would suggest.

It's not necessarily going to slow your vehicle down either, but it may mean using some extra revs. Power isn't all about energy per litre, because if it was diesels would be more powerful than petrols.

I wouldn't say a lack of power would be a reason to avoid biodiesel.

No, the outright destruction of your motors Injectors, combined with non economical fuel usage vs cost should be enough to avoid bio-diesel.

Interesting facts...

Most Common Rail and unitary injector failures in Europe... France...
Shortest life of a bio-diesel TD5.... 600 miles (2nd tank ever)

Most common cause of injector failure in UK... Biodiesel

Large TD5/Landrover company in UK... Stated Bio destroys the injectors due to changes under pressure....

Arguments for Bio, most based on old style injectors and cost savings.

Any proof for any of this??? The only failures I have heard of have been linked to either poor quality or unwashed biodiesel. There are plenty of people all around the world running TD4 and TD5 landrover diesels on good quality, washed biodiesel, without reliability problems or engine failures.

However it is true that most engines are not warranted by the manufacturers to run on biodiesel - but they are warranted to run up to 50% petrol in the fuel in places like siberia - which I am sure would do more harm than biodiesel.

Have a read here for more information.

okay so bio diesel up here in darwin is made from palm oil does it make a difference what it is made from ie:canola.palm oil.cooking fat.etc

Remember the John Laws ad "Oils ain't Oils"

When using any Bio the most important thing would have to be it's viscocity. In Bricklayers terms for DD How runny the **** is. As for what oils they use in the process it doesn't really matter , just don't risk it your TD5

Hi, I ran my MY2003 TD5 on South Australia Farmers Federation(SAF) in SA for 2 years without problem. It gave more power and better fuel milage without any problems.

BOll**Ks

My brother has been running his TD5 D2 for 4 months on Bio fuel in the UK. Says it goes better than with Diesel. But he does do a 3/4 tank dio and 1/4 tank diesel

Still havn,t had mine on the road enough to even think about it yet. I would like to do it though but there is no possible way my budget can afford any unexpected repairs so If I break it I will have to sell it to fix it.

well.. I can only re-iterate my own experiences..

no problems running home made B100 (100% biodiesel) in my 2001 TD5 D130.

biodiesel bob..
