Gas remains the fuel of choice for vehicle owners

Diesel prices, on the other hand, have reduced from a high of Rs 98.44 per litre on November 1, 2021, to Rs 89.62 per litre as on October 22, 2022, according to Indian Oil, and petrol prices from Rs 110.08 per litre (on November 2, 2021) to Rs 96.76 per litre now.

According to Mahanagar Gas, CNG has very little carbon and so it does not contaminate crankcase oil, giving a new lease of life to the engine.

Over the last year, CNG prices in Delhi (where gas is the most affordable in India) have risen by 51%. As per data from Indraprastha Gas, on November 14, 2021, CNG cost 52.04 per kg, which increased to78.61 per kg on October 8, 2022. Diesel prices, on the other hand, have reduced from a high of Rs 98.44 per litre on November 1, 2021, to Rs 89.62 per litre as on October 22, 2022, according to Indian Oil, and petrol prices from Rs 110.08 per litre (on November 2, 2021) to Rs 96.76 per litre now.

Despite this reducing price gap, however, auto analysts say CNG has an advantage over diesel (and, to an extent, petrol) as far as total cost of ownership of a vehicle is concerned, be it a personal car or a commercial vehicle.Saket Mehra, partner, Grant Thornton Bharat, told FE that as CNG prices have increased over the past year, CNG car sale bookings have declined by 10-15%, and some companies have reported a slight growth in customer preference for vehicles powered by petrol vis-à-vis CNG. “But due to high level of pending bookings slowly catching up with impending demand, the decline in sales is not immediately visible,” he said.

“Overall, sales of CNG-run passenger vehicles have remained unaffected, especially for entry-level vehicles, as they have a fuel efficiency improvement of about 30% over petrol. ”For example, Maruti Suzuki’s Ertiga CNG is Rs 95,000 costlier than petrol. But CNG has better fuel efficiency (26.11 km/kg in the Ertiga) than petrol (20.51 km/litre), and, therefore, far lower running costs (Rs 3 per km for CNG vis-à-vis Rs 5 per km for petrol). Maruti Suzuki calculated that if your run is 50 km per day, within three years you will be able to recover the extra money spent on buying the Ertiga CNG and from thereon, it’s savings all the way. If your daily run is more, the recovery will happen sooner. Therefore, in commercial vehicles (CVs), where the daily run can be as high as 400 km (data for 2020, compiled by Statista), CNG has an advantage over other fuels.

Gaurav Vangaal, associate director, light vehicle forecasting, S&P Global Mobility, told FE that in CVs it’s predominantly diesel versus CNG — there is usually little price difference between a CNG and a diesel CV — and with CNG having higher fuel efficiency, operators can save lakhs of rupees per year only on fuel. Another advantage is that in places such as Delhi, diesel-propelled vehicles have to pay 25% extra road tax over non-diesel vehicles.

Mehra added that higher fuel efficiency and easier availability of CNG have been a major attraction for CVs, since it directly translates to lower operational costs. “The CNG goods carrier segment grew 212% in FY22,” he said. “Even with a hike in CNG prices, the increasing availability of CNG stations (4,500 in 2022 and expected to touch 10,000 by 2030) and rising products with CNG powertrain, lower total cost of ownership over diesel vehicles, and restriction to entry of diesel in certain cities (especially in Delhi from October 1, 2022, to February 28, 2023), owning and running a CNG CV appears preferable.”What works for CNG is longer engine life. While the cylinder and fuel lines need proactive maintenance, CNG is beneficial for the engine.

According to Mahanagar Gas, CNG has very little carbon and so it does not contaminate crankcase oil, giving a new lease of life to the engine. The absence of any lead content in CNG helps avoid lead fouling of plugs, thereby enhancing plug life. As CNG enters the engine in the form of a gas (and not as a spray or mist like petrol), no carbon is generated during the combustion of CNG, reducing the chances of wear and tear.
