| Sulphur Content in Caltex Diesel |
|
Was surprised to learn that Caltex diesel contains a higher sulphur content than other suppliers. At the start of this year, the authorities relaxed the mandated suphur content regulation for Caltex because they did not have the manufacturing capacity to produce low sulphur diesel!! According to the magazine I was reading, Caltex is in the process of upgrading their refineries to produce mandated suphur content diesel.
I'm glad I do not use Caltex diesel, not because of the higher sulphur content, but because I find they are more expensive than most. '06 Disco 3 TDV6 SE Buckingham Blue

I had a concern about the black smoke that appeared from my D3 (and I was using predominantly Caltex diesel) but after the enhancement (LR applied software/hardware checking/updates) it was reduced dramatically.
Still using the same fuel but now my consumption has steadily increased so it is going for a check-up soon.
Recently read about a new fuel called SunDiesel that sounds promising but need to know more.

Leigh - I believe sulphur is unhealthy for catalytic converters but not sure if it is contributing to your rising fuel consumption, ie.clogging your catalytic converter. Is your oil consumption rising too? Black smoke normally is a result of abnormal oil consumption. I just put in a litre of oil in mine and it has just clocked 9k. Haven't checked if mine blows black smoke.. '06 Disco 3 TDV6 SE Buckingham Blue

Blue smoke normally means oil consumption.
Black smoke in a diesel usually means too much fuel being injected.
Mine put out black smoke under load before enhancement. Not now! Have a nice day!

Didn't someone else here have a problem with excessive oil consumption?? I'm too lazy to search. Have a nice day!

DiscoAtom, the smoke would appear at the traffic light grand prix. And usually I noted it when the lights of the car behind were filtered in my mirrors by my exhaust particulates as they dispersed into the atmosphere.
Jamo is right. The black smoke is associated with too much fuel being injected (and therefore being wasted) although I haven't really noticed any greater output of the smoke despite my increase in fuel consumption. Oil consumption is stable. Neither up nor down.

The diesel D3's do have catalytic converters fitted,
if there is an increase in exhaust black smoke, get the dealer to check for a DTC related to the air mass sensor (can't remember the exact DTC number), had this once on mine - no dash warning just an increase in smoke output and a slight reduction in power. A clear & re-read sorted it

Thanks for the heads up TFC. I will be getting mine checked soon. Just a few hundred more kilometres and I get the 24 000 km service.

Gee... some people might not like the refineries, where they make fuel with cat crackers! 
My father-in-law helped build the Caltex refinery at Kurnell and then worked there in the tank farm for about 38 years. I might ask him to investigate this issue - as I will be exclusively using Caltex diesel with the lease fuel card.

One of the reasons high output European diesels were not imported in Australia earlier was due to the high sulphur content on Australian diesel. I am not sure on this but I think, the a high sulphur content is detrimental to the catalytic converter.
The sulphur content issue with Caltex was at reported at the start of this year, I'm sure they would have upgraded their refineries by now. A recent article in a 4WD magazine have also indicated that they a including biodiesel (2% ?) in their diesel. '06 Disco 3 TDV6 SE Buckingham Blue

OK - I just found the following article:
http://www.caltex.com.au/about_news_detail.asp?id=858 which states: "The refinery's diesel hydrotreater unit is producing diesel to the new standards of a maximum 50 parts per million (ppm) of sulfur. This will reduce further to a maximum of 10ppm in 2009 (down from 500ppm in 2005)."
The article also mentions that the upgrade works have completed in both Lytton and Kurnell.
There are also pages which give specifics on their "ultra low sulfur" diesel:
http://www.caltex.com.au/products_oil_detail.asp?id=293
as well as their "new generation" diesel (which contains 2% biodiesel):
http://www.caltex.com.au/products_oil_detail.asp?id=332
I just had a look at the BP site and they also claim a max of 50ppm Sulphur.
