Protect Your Engine: Why the DOE’s New Interim Fuel Shift Means You Must Choose Your Diesel Very Carefully at the Pump
Your ride’s health is taking center stage as the DOE introduces Euro II fuels to steady the local supply. While this keeps the pumps flowing, the Truck Manufacturers Association is raising a red flag for owners of modern, Euro IV-compliant rigs. Higher sulfur levels in older fuel blends can be tough on sensitive engines, potentially affecting performance and longevity. To keep your lifestyle on wheels smooth, stay informed, check fuel labels carefully, and prioritize maintenance during this interim shift.

On the Department of Energy Department Circular No. DC 2026-03-0010
(Interim Introduction of Euro II/2 Petroleum Products)
OFFICIAL RELEASE: Truck Manufacturers Association Inc. | PUBLISHER: ADVAI
While the Truck Manufacturers Association, Inc. (TMA) acknowledges and supports the initiative of the Department of Energy (DOE) to ensure adequate fuel supply through the interim introduction of Euro II/2 fuels amid current global supply challenges, our association would like to emphasize that the implementation of this interim measure must be undertaken with utmost caution, supported by clear guidelines, proper safeguards, and comprehensive public information.
Modern vehicles currently operating in the Philippines, particularly those compliant with Euro IV/4 emissions standards, are engineered with advanced fuel systems and emission control technologies that are highly sensitive to fuel quality – particularly sulfur content. The use of Euro II/2 fuels, which have significantly higher sulfur levels, may result in adverse effects on engine performance, durability, and emissions systems.
Clear and accessible information must be made available to the public on how to determine vehicle compatibility with Euro II/2 fuels, including distinctions between Euro II/2 and Euro IV/4 compliant engines. The advisory requirements prescribed under the Circular is a positive step, and their strict and consistent implementation across all fuel retail outlets is strongly encouraged.
Furthermore, TMA recommends that industry stakeholders and relevant government agencies collaborate closely in disseminating accurate technical guidance, conducting public awareness campaigns, and ensuring that end-users, particularly fleet operators, transport groups, and individual vehicle owners fully understand the implications of fuel selection on vehicle performance, maintenance, and longevity.
While the introduction of Euro II/2 fuels may be necessary as a temporary measure, TMA strongly advocates that such implementation be time-bound, closely monitored, and aligned with the country’s long-term direction toward cleaner, more efficient, and environmentally sustainable fuel standards.
