Any Change to The Engine?

The BS-6 compliant petrol engine will have a few changes, but the changes wouldn’t be surpassing the technological beliefs associated with an IC engine.

Should I Buy BS6 Instead of BS4 Petrol Car?

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. As BS-6 petrol will do with lesser sulphur content, and it acted as a lubricating agent in the fuel. So, it is better to buy BS-6 car, though the BS-6 would not have any major effect on the BS-4 cars. So considering a BS-4 vehicle over the BS-6 is not a bad idea, how good but? Lets’find.
