The reasons to buy a BS-6 petrol car are many, the first to start with is they don’t pollute as much as the BS-4 car does. To calculate how less, the Carbon-Monoxide particles are limited at 1.0 g/km, the Hydrocarbons and Nitrogen oxides at 0.16 g/km and particulate matter at just 0.05.

Another reason is, the BS-6 cars will run with BS-6 fuel and they are designed to do so, while the BS-4 cars were designed to run on the BS-4 fuel. The BS-4 fuel would be out of market soon, and BS-4 cars will have to rely on the BS-6 fuel only, which is something not appreciable at all.
