Chevron Philippines Inc. (CPI), marketer of Caltex fuels and lubricants, has appointed Pongtorn “Bon” Tangmanuswong as its new General Manager and Country Chairman, marking an exciting new chapter for the company’s Philippine operations.

Bringing with him 17 years of experience across Chevron’s global operations, Tangmanuswong will oversee more than 600 Caltex service stations, 450 autoPro workshops, major commercial accounts, and five proprietary terminals nationwide. His leadership is expected to further strengthen Caltex’s foothold in the highly competitive Philippine fuel and lubricants market.
Tangmanuswong began his career at Chevron in 2008 and has since held key leadership roles in Procurement, Supply Chain, Engineering, Asset Optimization, and Special Projects across Asia-Pacific markets. Most recently, he served as General Manager and Country Chairman of Chevron (Cambodia) Limited, where he drove significant progress in terminal operations, supply and distribution efficiency, and market growth.
“It is an honor to step into the role of General Manager and Chairman at such an exciting time for our business. The Philippine market is dynamic, competitive, and full of untapped potential. I’m committed to leading with vision, energy, and collaboration. Together, we will challenge limits, seize new opportunities, and shape a successful, sustainable future,” Tangmanuswong shared.
He succeeds Billy Liu, who led CPI for nearly five years and will now take on a new role at Chevron’s headquarters in Houston.
Liu expressed confidence in his successor’s leadership, stating:
“Khun Bon’s and my terms as general managers of the Cambodian and Philippine offices have coincided. During that time, I witnessed his ability to deliver growth while putting people and partners at the center of his leadership. I am confident that CPI will continue to thrive under his direction.”
This leadership transition reaffirms Chevron’s commitment to expanding its Philippine operations and supporting the country’s growing demand for reliable, cleaner, and sustainable energy solutions.
