Shell Lubricants introduced Shell Rotella T4 NG Plus 15W-40 heavy-duty engine oil which is formulated for use in mobile natural gas engines as well as diesel and gasoline engines. The engine oil is particularly relevant for waste haul trucks and buses operating with 100 percent compressed natural gas (CNG) and liquefied natural gas (LNG) fueled engines.
“Shell Rotella T4 NG Plus 15W-40 meets the specifications for natural gas, diesel and gasoline engines, making it a true multi-vehicle engine oil that will help fleets consolidate the number of engine oils they need in their shop,” said Megan Pino, Shell Rotella global brand manager. “We continually look at the needs of fleets and develop engine oils to keep their vehicles performing well while helping to minimize maintenance complexities.”
Natural gas engines, with their spark combustion, run significantly hotter than diesel engines. Shell Rotella T4 NG Plus 15W-40 has been specially formulated for use in natural gas-powered vehicles in order to manage their high heat and provide the necessary engine protection.
According to the company, Shell Rotella T4 NG Plus 15W-40 offers several key benefits:
- Piston and engine cleanliness. An optimized balance of detergent and dispersancy provides good piston and engine cleanliness and ensures long and efficient operation.
- Ignition system protection. The formulation contains additives to control the deposit formulation in the combustion chamber to help prolong the life of valves and spark plugs.
- Emissions system compatibility. The low ash formulation helps protect the exhaust catalysts and particulate filters found on the latest low emission vehicles.
- Suitable for natural gas, diesel, and gasoline engines. Mixed fleets can benefit from using one oil for multiple engine type, thus minimizing maintenance complexity.

API CK-4 certification for cold weather engine oil
Shell also announced that its Shell Rotella T6 Full Synthetic 0W-40 heavy-duty diesel engine oil is now licensed as API CK-4 service category. The engine oil is designed to meet the needs of advanced engine technologies for both on-road and off-road vehicles and equipment.
“Shell Rotella T6 Full Synthetic 0W-40 heavy-duty engine oil is intended for engines operating in tough, cold weather,” Pino said. “This low-viscosity engine oil, which now meets the current CK-4 engine oil standard, provides the low-temperature performance needed to keep trucks and off-highway equipment moving in harsh conditions.”
Shell Rotella T6 Full Synthetic 0W-40 heavy-duty engine oil is formulated with the company's Triple Protection Plus technology. The engine oil is designed to provide protection against wear, deposits, and oil breakdown, and offers pumpability at low operating temperatures. Shell Rotella T6 Full Synthetic 0W-40 is suitable for on-road and off-road applications requiring API CK-4 engine oil. The low ash formulation helps protect the exhaust catalysts and particulate filters found on the latest low emission diesel vehicles.
Key benefits of Shell Rotella T6 Full Synthetic 0W-40, according to the company:
- Wear performance. Advanced wear protection for long engine life.
- Deposit control. The advanced multi-functional dispersant additives in combination with synthetic base oils provide protection against the effects of soot, dirt, and other contaminants.
- Heat resistance. The oil resists breakdown by heat to provide continuous protection throughout the service interval.
- Protection in extreme climates. Provides improved low temperature flow compared to a conventional SAE 15W-40.
- Emissions systems compatibility. Advanced low-ash formulation helps control blocking of or poisoning of exhaust after-treatment devices, helping maintain DPF service life.
