Does anyone run they 2.4jtd on bio fuel

Hi thinking of running my 2001 156 2.4jtd on bio fuel.
Has anyone had problems with it?

Has to be proper bio diesel, roughly the same viscosity of pump diesel, otherwise you will come into problems. You can't run these on filtered waste vegetable oil.

When my previous engine was failing and i knew i was going to change it, to keep costs down i used bio fuel. It made the engine absolutly useless and gave it absolutely no power, was extremely rough and shook a lot and it also began eating the injectors and fuel filter bacame knackered fairly quickly. So I dont think the jtd can handle bio fuel. You can try as my engine wasnt healthy but i honestly wouldnt bother

Do Alfas have Pierburg fuel pumps?

Pierburg says:

Reviews performed within the scope of our quality management program have resulted in the finding that the use of bio diesel, especially in the case of bio diesel of low quality can cause, after a short operating time, the following functional impairments and damage to our electric fuel pumps:
- Deposits will clog filters and block the pumps
- Deposits on commutators have an isolating effect
- Carbon brushes will burn out after a short operating time
- Contact corrosion will destroy metal parts

Bio and SVO will take out the electric pump in the fuel tank first if the viscosity of the fuel is not up to diesel standards. If the tank pump goes, the high-pressure pump will follow suit and seize, which usually results in a snapped cam-belt, and you know where a snapped cam-belt leads you.

Some common-rail diesels are less tolerant of bio-diesel as the additives tend to damage rubber seals in the fuel system. Easiest way to find out if you are able to use it is to ask an Alfa dealer if it can be used or not. Most manufacturers state in their handbooks if they are compatable with biofuels.

Personally i wouldn't run the risk, i've seen the damage made to a Punto JTD engine after it lunched itself on bio.

I wouldnt risk it, even for the cost savings. Knowing my luck I'd need a new engine!

Its not really that great for the environment either, if that's a concern.
