Factory-Fitted (S-CNG / i-CNG) vs Aftermarket Sequential Kit

1

Factory-Fitted CNG (OEM Approved)

Vehicles like Maruti Suzuki S-CNG, Tata i-CNG (twin cylinder technology), and Hyundai Hy-CNG feature factory-tuned dual ECUs, integrated fuel gauges, reinforced suspensions, and full OEM warranty coverage.

2

Aftermarket Sequential CNG Kits

Sequential injection kits (from brands like Lovato, Motozen, Tomasetto) utilize dedicated gas injectors for smooth acceleration with only ~8–12% drop in peak power. Ensure the kit is government RTO-approved.

3

Mandatory 3-Year Hydrostatic Cylinder Testing

Under Petroleum and Explosives Safety Organisation (PESO) regulations, all vehicle CNG cylinders must be tested and certified every 3 years. Running an expired cylinder is hazardous and illegal.

Frequently Asked Questions (FAQs)

Does running on CNG reduce car engine life?
CNG burns cleaner than petrol with zero carbon deposits, which keeps engine oil cleaner for longer. However, because CNG lacks the lubricating properties of petrol, it is recommended to start the car on petrol daily and service spark plugs and valve clearances at regular intervals.
Is RTO endorsement required after installing a CNG kit?
Yes, getting your vehicle's Registration Certificate (RC) and Car Insurance policy endorsed with the fuel type changed to 'Petrol/CNG' is legally mandatory across all Indian states.
