Robert, I had understood that the standard ISO EN 590 related soley to the qualities of the FUEL, whereas the standards of Euro3, Euro4, Euro5, etc, only apply to the measurement of the various exhaust gases and particulates(Emissions). While the two have some relationship, they are not the same.

Excellent post Robert. I only just read it now although you wrote it some years back.
The distillate story parallels that of lead in petrol back in the 80s. Lead was removed from petrol, not for the much publicised lead poisoning of children, but to allow the use of catalytic converters. Lead (tetra ethyl lead) coats the active materials in the cats and renders them inactive. Just like the sulphur in diesel. Lead adds lubricity to petrol and its removal caused engine problems. Petrol engines had to be re-engineered to suit ULP. That's why we had a Nissan engine in the VL commodore.
Seems we are getting second rate ULSD here. I have a friend with a 5 cyl common rail Alfa and he has a lot of trouble with the local fuel. I guess he should try Bio.
Personally, i don't have to worry about warranties as I don't buy vehicles that new (let someone else de-bug and carry the depreciation). I can run my vehicles on vegetable oil and biodiesel and take responsibility for my action.
It is about time that manufacturers built engines specifically to run on biofuels so that we can ditch reliance on petroleum products.

Low sulphur diesel is not good enough. It has 500 ppm sulphur whereas the vehicle manufacturers specity 20 ppm.

two issues here;
1. there isn't and won't ever be enough veg oil to support fuel needs for the masses IMO. so why the hell would manufacturers bother when only say 1% of their market would give a toss about veg compatability. Think about it seriously and you'll understand you and me are just a piss in the ocean.

2. Have PM about.

i have read your posting of 2005. It is very positive and has been a great help in making up my mind about biodiesel. The manager at the biodiesel supply in town, who happens to be australian, is also very positive about it but he seemed to have reservations. He would not give me an assurance that there would not be a problem and his concern was with the oxidation of biodiesel and something to do with the iodine value. They make their diesel from soya and that has a value of about 70. He was worried that it might cause blockages in the catalytic converter. What do you think the effect of that can be?
