Lubricants suppliers are facing increasing challenges due to the ongoing military conflict in the Persian Gulf, which is impacting the certification process for the GM Dexos licensing program. Industry groups are now calling for temporary relief measures to continue supplying critical markets, including the United States
According to the Independent Lubricant Manufacturers Association (ILMA), the ongoing conflict has had a detrimental impact on the availability of Group III base oils due to damage to key production facilities. In addition, the conflict resulted in the cessation of shipping through the Strait of Hormuz, hampering an important global supply route.
ILMA states that the majority of Group III base oils used in the United States are sourced from the Middle East, and therefore, lubricant manufacturers are now struggling to obtain sufficient ingredients to maintain the required formulations under GM’s Dexos standards. In response, ILMA has formally petitioned GM requesting temporary flexibility in the Dexos certification framework.
The organization is seeking several important accommodations, including extensions of deadlines for testing and certification, suspension of enforcement due to certification deficiencies, faster approval of interim base oil substitutes, and efficient communication between GM and suppliers.
“This is an extraordinary situation that lubricant manufacturers cannot control,” said ILMA CEO Holly Alfano. “Our members remain fully committed to maintaining the performance and quality standards required by API and GM. The temporary relief we are requesting will allow the companies to continue supplying the market while facing supply disruptions on an unprecedented scale.”
GM’s Dexos specifications are an important benchmark for engine oil performance across its vehicle lineup, ensuring that products meet stringent requirements for lubrication performance under high pressure, fuel efficiency optimization and emissions compliance. ILMA has emphasized that its request is closely related to “force majeure” conditions and is not intended to undermine Dexos standards. Rather, the goal is to provide short-term flexibility so manufacturers can continue to supply lubricants that meet requirements during the current supply disruption.
