The Truck Manufacturers Association, Inc. (TMA) has backed a government move allowing the temporary use of lower-grade fuel, but warned it must be enforced with “utmost caution” to avoid damaging modern vehicles.
The group expressed measured support for Department of Energy Circular No. DC 2026-03-0010, which permits the interim rollout of Euro II petroleum products amid global supply constraints.
TMA said the policy could help stabilize fuel supply but stressed the need for clear safeguards, strict enforcement, and sustained public information campaigns. It flagged risks for vehicles built to Euro IV emissions standards, which dominate the Philippine market and rely on more advanced fuel and emissions systems.
“Euro II fuels contain significantly higher sulfur levels, which may adversely affect engine performance, durability, and emissions control systems,” the group said, citing potential long-term maintenance costs and environmental impact.
The association called for accessible guidance to help motorists determine fuel compatibility, noting that misuse could affect both private vehicles and commercial fleets. It welcomed advisory provisions under the circular but urged regulators to ensure consistent compliance across fuel stations nationwide.
TMA also pressed for closer coordination between industry players and government agencies to disseminate accurate technical information, particularly to fleet operators and transport groups that could face operational disruptions.
While recognizing the measure as a short-term solution, the group emphasized that the use of lower-standard fuels should remain temporary and tightly monitored. It added that the policy must stay aligned with the country’s broader push toward cleaner, higher-quality fuel standards.
The DOE has yet to release detailed implementing guidelines, which industry players say will be critical to minimizing risks and ensuring a smooth transition during the supply crunch.
