This will let third-party companies to install this alternative fuel kits to any BS-6 petrol/diesel car. As of now, only BS4-compliant models are permitted for retro-fitment of CNG/LPG conversion kits.

Manufacturers like Maruti Suzuki, Hyundai, and Tata Motors are offering factory-fitted CNG kits on a few of their cars, while no model comes with a factory-fitted LPG kit currently. By allowing retro-fitting in BS-6 cars, car buyers will now have a lot more options available to them.

As per the notification, the type approvals for vehicles retrofitted with LPG/CNG kits shall be valid for 3 years from the date of issue of such approval and shall be renewed every 3 years.
