Somebody will know... How long ago was it that Diesel fuel had the Sulpher content reduced here in Australia.  I remember BP having to pay out millions to car owners to replace seals in fuel systems that leaked. My Grey import Tarago had the whole back end covered in diesel. I was sent to a diesel mechanic in Springwood Brisbane to have it fixed. Took less than an hour and no cost to me.

Now many years later we find out that the Govt hasn't followed much of the rest of the world by reducing High Sulpher petrol here.

A good article, John (Rockylizard)

I was unaware that we had high sulpher content, in our petrol

I do recall, (going from memory), that we went unleaded, as the authorities found too much lead in the air, in the cities

It appears that this may have been affecting the brain power of city schoolchildren, in comparrison to the rural schoolchildren

 About 20 years after a city anywhere in the world stopped using lead in fuel. Crime rates dropped according.

Mmmm, interesting Rocky.

Maybe we need to get some 91 and 95 RONDA fuel to even out the playing field.

Agree with Terry here there is something amiss or the article is fiction, as we get about 90% of our fuel from China, Singapore & South Korea which is produced at 10 ppm sulfur the producers would then have to add sulfur up to 50 ppm to export to Australia, this is unlikely
The article seems to be assuming that we produce all our own fuel through our own refineries, when only 10% is the fact.

Clear as mud, Is the Australian refined stuff trucked separately? Does it get mixed with imported stuff? Does it only go to certain stations? Unlikely. So maybe the articles should have said 10% of petrol in higher in sulfur, but we don't know if you will ever have a tank of 50-150 ppm in you car ever.

Just more BS, this time from the Industry. It is well known by people in the running of wells that 'light sweet'crude oil can be put directly into an older diesel straight from the well unrefined. This is the preferred crude for refining.
The industry report quoted suggests the following....

'Much of Australias crude oil production is also of a quality (light sweet) which is very commercially attractive for processing in other countries. Australian refineries require a blend of crude oils to produce the product slate demanded by Australian fuel users'.

Where Wiki and others suggest....

'Sweet crude oil contains small amounts of hydrogen sulfide and carbon dioxide. High-quality, low-sulfur crude oil is commonly used for processing into gasoline and is in high demand, particularly in industrialized nations. Light sweet crude oil is the most sought-after version of crude oil as it contains a disproportionately large fraction that is directly processed (fractionation) into gasoline (naphtha), kerosene, and high-quality diesel (gas oil). The term sweet originates from the fact that a low level of sulfur provides the oil with a mildly sweet taste and pleasant smell. Nineteenth-century prospectors would taste and smell small quantities of oil to determine its quality'.[3]
