The technology demonstration period will give oil marketers and additive suppliers the time and framework needed to develop and test candidate oils against performance targets. These target limits, agreed upon in late 2024, will be finalized at the end of the demonstration period to receive approval and balloting from API and ASTM by December 2025.\u003C/p\u003E\r\n\u003Cp\u003E\u003Cb\u003EWhat is the PC-12 mandatory waiting period before commercial licensing in 2027?\u003Cbr\u003E\r\n \u003C/b\u003EThe first licensing date for PC-12 engine oils will be January 1, 2027, following a mandatory 12-month waiting period throughout 2026. This waiting period provides the time needed for the oil manufacturers to complete the category's engine testing requirements. With engine testing in high demand, the extra time allows oil marketers to complete development and compliance testing to ensure that oils will be ready to be introduced into the market on the first licensing date.\u003C/p\u003E\r\n\u003Cp\u003E\u003Cb\u003EHow Do API Chemical Composition Limits Lower Environmental Impact?\u003C/b\u003E\u003Cbr\u003E\r\nA core component of this process is validating that the candidate oils meet chemical composition limits set by the API New Category Development Team (NCDT). These limits are designed to maintain durability and protect sensitive aftertreatment systems while lowering environmental impact. That means stricter constraints on phosphorus, sulfur, and sulfated ash levels—all without sacrificing the protective capabilities fleets and drivers rely on.\u003C/p\u003E\r\n\u003Cp\u003E\u003Cb\u003EWhat Field Testing Does Rotella Do To Validate PC-12 Oils? \u003C/b\u003E\u003Cbr\u003E\r\nAnother key component of technology demonstrations is evaluating performance in the field. Shell Lubricants conducts field trials with its Shell Rotella PC-12 candidate oils in fleet trucks alongside lab testing. These real-world evaluations are crucial for ensuring that the oils pass technical specifications and stand up to the rigors of daily fleet operation. From heat and soot to start-stop conditions and long-haul cycles, these trials offer robust validation that the oils deliver the durability and performance fleets expect.\u003C/p\u003E\r\n\u003Cp\u003E\u003Cb\u003E\u003Ca href=\"https://rotella.shell.com/en_us/info-hub/diesel-oil-specs-tech-standards/pc-12/additives-at-the-core-of-api-pc-12-oils.html\"\u003EMore on the PC-12 oil additives involved in lab testing\u003C/a\u003E\u003C/b\u003E\u003C/p\u003E\r\n\u003Cp\u003E\u003Cb\u003EWill Shell Rotella Bring New Oils PC-12 Oils To Market?\u003C/b\u003E\u003Cbr\u003E\r\nAPI, oil marketers, additive suppliers, engine manufacturers and other industry parties are well on their way to adopting PC-12 specifications.
