although a lower-viscosity oil should provide less restriction as it flows through the filter, which can help improve engine efficiency and fuel economy," Sheumaker says. The new oil designated for pre-2017 engines will be PC- 11A, classified as CK-4. It will replace SAE 40-weight oils. CK-4 products "will be com- pletely backwards-compatible with all current vehicles," Arcy says. "They will be designed with improved oxidation resistance, shear stability and aeration control." PC-11B, which will replace some SAE 30-weight oils, will be designated as FA-4. FA-4 oil will also meet those new requirements while add- ing lower-viscosity grades that are not suitable for older engines. Whitacre says the split cat- egory designation primarily reflects 30-weight oils, since 40-weight oils have viscosity that is much higher than the FA-4 category will allow. How- ever, he notes the possibility for confusion about 30-weight oils in the PC-11 framework. Both 10w-30 and 5w-30 PC-11 formulations could be marketed as CK-4 or FA-4, depending on their high-tem- perature high-shear viscosity, Whitacre says. API is trying to figure out exactly how the industry will communicate all of this information to drivers, technicians and fleets. Some users, such as a firm operating older equipment and mixed engine types, "will only see a small impact from PC-11," says Paul Cigala, com- mercial vehicles applications engineer for ExxonMobil Fu- els & Lubricants. Those fleets may only need to transition from CJ-4 to the newer CK-4 formulation. "In comparison, a fleet with a mix of older and newer equip- ment may choose to stock both CK-4 and FA-4 formulations," Cigala says. "CK-4 oils will be suitable for use in both older and newer equipment, but if the fleet is looking to enhance the fuel economy of its newer en- gines, it will likely decide to use the new FA-4 formulation."
