Sulphur in fuel contributes directly to the emission of sulphur dioxide into the environment and while the majority of sulphur dioxide emissions are produced by industry and domestic heating, a significant amount is also emitted by motor vehicles.
Sulphur dioxide, in turn, leads to the formation of sulphate particles which can be associated with a variety of health effects, and contribute to the visible haze familiar to anyone who has walked or cycled alongside traffic congested roads.
The sulphur present in fuel reduces the efficiency of your car’s catalytic converter which means that over time it loses its ability to reduce the harmful emissions from your engine.
