The Truck Manufacturers Association, Inc. (TMA) said it supports the Department of Energy’s temporary move to allow the interim introduction of Euro 2 petroleum products, but stressed that the measure has to be handled carefully and supported by clear guidance for motorists and transport operators.

In a statement, TMA said the Department of Energy issued Department Circular No. DC 2026-03-0010 to help protect fuel supply amid ongoing global supply concerns. At the same time, the group pointed out that the use of lower-grade fuel could create problems for many newer vehicles now on Philippine roads.

TMA said many vehicles in the country, especially those built to meet Euro 4 emissions standards, use fuel and emission-control systems that are more sensitive to fuel quality, particularly sulfur content. Because Euro 2 fuels carry significantly higher sulfur levels, the group said their use could affect engine performance, durability, and emissions-related components.

The association also said motorists should be given clear and easy-to-understand information on whether their vehicles can use Euro 2 fuel. It added that the advisory requirements in the DOE circular are a good starting point, but these should be applied consistently across fuel stations.

TMA also called on government agencies and industry players to work together on technical guidance and public information efforts. It said this would help fleet operators, transport groups, and private vehicle owners better understand how fuel choice may affect vehicle performance, maintenance needs, and long-term reliability.

While it acknowledged that Euro 2 fuels may be needed as a temporary measure, TMA said the policy should remain limited in duration, closely monitored, and consistent with the country’s longer-term push toward cleaner and more efficient fuel standards.
