Shell Rotella's T6 Multi-Vehicle 5W-30 full synthetic oil is designed for versatility, meeting the API CK-4 specification for Class 8 Trucks as well as API SN specification for gasoline trucks and vans.

The oil is aimed at owners of mixed fleets with Class 6-8 diesel trucks and gasoline powered pickup trucks and vans. To do this, Shell designed and tested the T6 MV 5W-30 for needed wear, oxidation and depsoit control needed in modern commercial diesel engines while also exceeding the requirements for the API SN performance category of gasoline engines.

“With Shell Rotella T6 Multi-Vehicle 5W-30, it is now possible for hard working fleets or businesses that run diesel and gasoline powered engines to carry a single oil that offers numerous benefits,” said Megan Pino, Shell Rotella global brand manager. “The full synthetic oil has been engineered to provide protection under the most severe engine conditions for both diesel and gasoline engines.”

The oil contains Shell's Triple Protection Plus technology, combining additives and synthetic base oils to protect against wear, deposits, and oil breakdown, while also offering better fuel economy with it's lower viscosity. T6 MV 5W-30 oil demonstrated strong oxidation resistance in the Volvo T-13 oxidation  test, according to Shell, controlling acid build up, preventing oil thickening, and exceeding the API CK-4 limits for oxidation. 

The T6 MV 5W-30 Full Synthetic oil is designed to work better at low temperature oil flow when compared to Shell's own T4 Triple Protection 15W-40. Through testing, Shell says the T6 MV 5W-30 oil had better cold cranking properties and low temperature pumpability than the T4 oil at -30 and -35 degrees Celcius, respectively. 

"I think we've been able to demonstrate that there's no loss in performance, in durability, between having our 15W-40 T4 Triple Protection compared to our T6 MV 5W-30," said Jason Brown, global technology manager for heavy duty diesel engine oils at Shell. "Starting with that baseline [in performance], the T6 itself offers many benefits in and above a 15W-40. That level of viscosity change is opening a window to fuel efficiency that you don't have at 15W-40, which is cost savings. This is dollars that you can keep in your pocket."

Shell also announced the T5 Ultra 10W-30 synthetic blend diesel engine oil, which meets the API FA-4 service category for 2017 diesel engines. The low viscosity oil has been formulated to offer better fuel economy and improved high and low temperature performance while meeting the reuqirments for many low emissions engines beginning in 2017.

“Shell Rotella T5 Ultra 10W-30 synthetic blend is designed for next-generation on-road diesel engines to help maximize fuel economy without sacrificing engine protection,” said Pino. “It is designed to provide protection that adapts to driving conditions and is formulated to minimize oil consumption and protect exhaust catalysts and particulate filters.”
