Sometimes, AFTON retires old handbooks to force customers to use their new "AFTON SmartSpec" digital tool. If you absolutely need the static 2022 PDF:
The Afton Specification Handbook 2022 covers a wide range of topics, including: You can track current guides, data sheets, and
For the 2022 edition, the relevance of such a resource is paramount. As engine technologies become more sophisticated, the margin for error in fuel and lubricant composition narrows. The handbook provides the definitive "recipe" for compliance, outlining the physical properties and performance metrics that additives must help fuels achieve. By standardizing this information, Afton empowers fuel marketers and refiners to ensure their products meet legal and performance thresholds, thereby protecting engine integrity and consumer investment.

These standards replace GF-5, offering enhanced fuel economy and protecting against the detrimental effects of LSPI in turbocharged gasoline direct injection (TGDI) engines. Afton’s technology is designed to meet these stringent requirements while optimizing additive treat rates. 2. API SP and API SP Resource Conserving Detailed bench, rig, and engine test parameters
I should also check the Afton Chemical website's resources section to see if the handbook is listed there. Maybe the handbook is behind a login or registration. I will search for "Afton Chemical knowledge center" and "Afton Chemical resources". search results for "Afton Chemical knowledge center handbook" show a 2013 article (result 0) and other pages from 2011. These are likely outdated. The search for "Afton Chemical resources specification handbook" did not yield the handbook.
The Afton Specification Handbook is a key industry reference for lubricant specs, featuring significant 2022 updates including the ACEA 2022 HDEO sequences and new On-Road HDEO guidelines. These current specifications and detailed data sheets for PCMO and HDEO are accessible via the official Afton Chemical website and resources.

While the baseline ACEA E4 and E7 categories were maintained, the physical testing protocols changed. The legacy OM501LA engine test was phased out in favor of modern piston deposit evaluations designed to mirror highly boosted, lower-emission heavy diesel architectures. 3.
