Euro 3 gasoline refers to a specific standard for the quality of gasoline set by the European Union. It is designed to reduce harmful emissions from vehicles by setting limits on the amount of sulfur and other pollutants in the gasoline. Euro 3 gasoline has a sulfur content of no more than 150 parts per million (ppm), which is lower than the previous Euro 2 standard. This cleaner fuel helps to improve air quality and reduce the environmental impact of vehicle emissions. **
