Lower the Sulphur content? I work in a Refinery and the Diesel goes out to all the vendors from exactly the same storage tanks! Companies like Shell inject "additives" but they will have no effect on Sulphur levels. The benefits from these additives are slightly dubious in my opinion as the standard diesel is manufactured to be entirely suitable for modern engines.
Interestingly vendors keep the details of these additives a closely guarded secret, me being a bit of a cynic am suspicious that it could maybe be a means of making more profit. |

I recall student days when I worked the bars in Edinburgh and when we ran out of McEwans export we would connect Tartan Special to the pump - people would drink the Special from the Export tap saying that it tasted so much better than that Special rubbish!!! (for the English, Special is cheaper than Export and weaker in strength ) This is an example where if you believe it is better then it will be better - even when the same - my opinion on these 'special fuels' is similar - some people believe that because it costs more it must be better |

However, I prefer to pay extra for premium diesel for two reasons: I believe that the premium fuel may contain less biodiesel. In Oz they can add up to 5% biodiesel before having to declare the percentage. I believe that the discount fuel would have the maximum 5% and premium fuel perhaps less. The premium fuel probably produces less soot and consequently less work is needed in the DPF. I have no proof that either of these beliefs are correct.

I like the beer analogy, Tartan Special, ah....that takes me back a bit, come to think of it I was a student in Edinburgh! (only kidding)
For some years now Refinerys have had to produce ULSD or Ultra Low Suphur Diesel. The main purpose of this was to reduce Sulphur Dioxide emissions from vehicle exhausts (for EC emissions regs). I think that common sense has to prevail here, as I understand it the regen frequency is initiated by the ECU. I would find it hard to believe that this will go ahead if the engine is not sufficiently heated up. When the engine has reached normal temperature revving the guts out of it will not make any difference. If you miss a complete regen once or twice it should not mean the end of the world, it is inevitable that some fuel will find its way into the oil between service intervals. Vehicles that experienced excessive contamination should have had the oil and filter changed out FOC, as customers we should not accept draining down. It looks to me as though Volvo have acted on some vehicles injecting too much diesel during the regen and that is what the re-programming does. Just remember, there is only one Refinery in Scotland and it makes 90% of all the fuels sold on the forecourts here, Tesco, Asda, BP, Shell the lot. Paying extra for additives is a bit like ....... a car placebo...... makes us feel a bit better but we don't quite know why. Anyway, had my R Design Ice White Geartronic for about 6 weeks now and am very pleased with it, love the forum, aren't we all a load of sweetiewives! |

Their response is "Apart from the additives in Vortex Diesel, all the other properties of the fuel are the same as our "ordinary" Diesel. The Cetane Number of both diesels is typically around 50 - 52 and both products must meet the Australian Specification for Diesel fuel. " and the additives are "You are correct in saying the difference between Caltex Diesel and Caltex Vortex Diesel is that Vortex Diesel contains a very effective fuel system cleaner (particularly injectors), and an anti-foam (to promote speedier filling), while Caltex Diesel does not. In addition, the Vortex Diesel also has a touch of perfume, to make it smell more pleasant if you accidentally spill some on yourself ( mainly for the ladies). Neither of these Diesels contain Biodiese" So I wouldn't worry too much if one can't find premium diesel for the occasional tankful. |

Thanks for that clarification about the premium diesel. I regard any diesel from Caltex, Shell and BP as premium fuel and had not considered the best of the best choices. If Caltex add no biodiesel at all I will try to use it when possible.
In clarification of my previous statement, I avoid the discount independents such as SAFF and United for diesel because both promote the use of biofuels and presumably add as much biodiesel as they are allowed, up to 5%. Some outlets sell B20 and even B100, if you choose. Conversely, I choose to use their bio alcohol enhanced petrol, up to 10% alcohol, for my petrol engine cars. Generally these discount fuels are cheaper and I am happy to promote Australia growing its own fuel. However, home grown biodiesel additives may not be the best choice for the rising oil level problem.

a very valid point, but given my DPF issues I'll err on the side of caution with every aspect of my car including spending a little extra on premium fuel if there any chance it will reduce the frequency that my engine decides to mix some of it with my oil. |

I guess that the post from ScotGC at
http://www.volvoforums.org.uk/showthread.php?t=104713 shows that not only is the spelling poor in the extract you found, but also that the figures are woefully incorrect At least we now have some attributable information from BS EN 590. |
