Afton Chemical Launches HiTEC® 65522 Gasoline Performance Additive Series Approved for TOP TIER+™ Gasoline

RICHMOND, Va.--(BUSINESS WIRE)--Afton Chemical Corporation, global leader in Gasoline Performance Additives (GPA), is proud to announce the launch of its HiTEC^® 65522 GPA series, now approved for use in TOP TIER+™ gasoline. This innovative additive series is designed to meet the evolving needs of modern engine technology, particularly Gasoline Direct Injection (GDI) engines, which are now utilized in 74% of new vehicles in North America, according to the U.S. EPA recent automotive trends report.

Twenty years ago, a group of original equipment manufacturers (OEMs) established the voluntary TOP TIER™ standard to enhance fuel detergency and optimize engine performance. Recognizing the advancements in engine technology and the need for updated standards, these OEMs have introduced the revised TOP TIER+™ standard. This new standard includes additional requirements to address potential deposit issues in GDI engines, ensuring cleaner and more efficient fuel options.

The new TOP TIER+™ standard, revision G, published in early January, includes two new test methods using a GM LHU engine. The first test evaluates injector deposit control by measuring injector fouling and particulates. Injector fouling can lead to poor spray patterns, compromised fuel delivery, reduced fuel economy, and increased particulate emissions. The second test focuses on protection against stochastic pre-ignition (SPI), a harmful pre-ignition event that can occur in modern downsized engines and potentially lead to engine failure.

In anticipation of these changes, Afton Chemical has developed the HiTEC^® 65522 GPA series, our most effective chemistry to date. They are specifically formulated to maintain excellent control of intake valve deposits while providing superior deposit control for direct injection engine technology. These additives ensure optimal engine performance and longevity, aligning with the stringent requirements of the new TOP TIER+™ standard.

"We are excited to introduce the HiTEC^® 65522 GPA series to the market," said Gerardo Alvarez, Marketing Director for the Americas at Afton Chemical. "Our team has worked diligently to develop an additive that not only meets but exceeds the new TOP TIER+™ requirements. This launch underscores our commitment to providing innovative solutions that support the latest advancements in engine technology."
