[QUOTE="astroboy, post: 377181, member: 4527"] Johorian can use loo... just need to go down to S'pore once a month to fill up.. :p Year, Standard, Specification. 1994, Euro 1, Maximum sulphur limit of 0.2% (wt.) = 2,000 ppm for all gas oils, including diesel fuel. 1996, Euro 2, A maximum sulphur limit of 0.05% (wt.) = 500 ppm for diesel fuel. 2000, Euro 3, A maximum sulphur limit of 0.035% (wt.) = 350 ppm and cetane number of 51 for diesel fuel. 2005, Euro 4, A maximum sulphur limit of 0.005% (wt.) = 50 ppm for diesel fuel. “Sulphur-free”10 ppm sulphur diesel fuel must be available for highway vehicles. 2009, Euro 5, A maximum sulphur limit of 0.001% (wt.) = 10 ppm (“sulphur-free”) for diesel fuel for highway and non road vehicles Next, Euro 6, single digit sulphur < 10ppm. Update: So why high sulphur no good? Sulphur in diesel forms sulphur oxides during combustion, which promotes particulate formation in the exhaust gas. Sulphur oxides further react with moisture present in the combustion chamber to form sulphuric acid which causes [B][COLOR="Red"]corrosion on the cylinder liner piston, ring and and piston[/COLOR][/B]. Low sulphur diesel reduces these phenomena substantially. This also enables an increase in oil drainage intervals as basic additives in the engine oil that sustain Total Base Number (TBN) have a much reduced depletion rate. Sulphuric acid formed by combustion of sulphur in diesel play a major role in increasing engine wear. Sulphur in diesel leads to the formation of sulphate particulates. In the engine oil, these cause [COLOR="Red"][B]depletion of the additives[/B][/COLOR] and [B][COLOR="Red"]thickening of the engine oi[/COLOR][/B]l. Same phenomena with high sulphur petrol thickens the engine oil is a petrol engine. The sulphate particulates, that leave the exhaust and that form in the air from sulphur dioxide emissions, also negatively effect air quality.
