In Australia they are bringing in low sulphur diesel as part of environmental requirements. A friend told me that this will shorten the life of the fuel pump seals as it does not lubricate as well as the older type of diesel. Is this true and has anyone have detailed information on this? I have a number of diesel engines including 2 Daihatsu Rocky 4X4, several Kubota and several MF Perkins powered tractors etc.
