Unisol Eco Shield is a 20W-50 engine oil (API SM) made in Rajkot, Gujarat by Satyam Petroleum for vehicles that run on CNG or switch between CNG and petrol. CNG burns hotter than petrol and, as a dry gas, gives the valves and seats none of the lubrication liquid fuel provides, so a CNG engine puts heavier thermal stress on its oil. Eco Shield is formulated for that load, with extra protection against wear, oxidation and deposits. It suits CNG cars, auto-rickshaws and bi-fuel engines where the manufacturer specifies a 20W-50 grade.
Specially formulated for CNG-powered engines, which run hotter and need extra protection against wear and deposits.
Unisol Lubricants manufactures 1 cng engine oils at its ISO 9001:2015 certified plant in Rajkot, Gujarat, India.
Eco Shield 20W-50 for petrol and CNG vehicles. CNG engines run hotter and leaner, so this oil delivers extra protection against wear, oxidation and deposits for a longer, cleaner engine life.
A dedicated CNG oil is recommended. CNG engines run hotter, and the dry gas gives no lubrication to valves and seats, which increases oxidation and deposits. An oil formulated for CNG, such as Unisol Eco Shield, is built for that extra stress.
Follow the grade in your vehicle manual. Many CNG cars and auto-rickshaws in India use 20W-50, while some newer engines specify a lighter grade. Unisol Eco Shield is a 20W-50 for engines that call for it.
