OFFICIAL RELEASE: Chevron Philippines : PUBLISHER: ADVAI
Manila, Philippines, October 2, 2025 — Chevron Philippines Inc. (CPI), marketer of Caltex fuels and lubricants, has appointed Pongtorn “Bon” Tangmanuswong as its newest General Manager and Country Chairman.
As CPI’s top executive, Tangmanuswong will bring his 17 years of experience with the energy company in leading CPI’s operations across more than 600 Caltex service stations, 450 autoPro workshops, major commercial accounts, and five Chevron proprietary terminals nationwide—further strengthening the company’s presence in the Philippine fuel and lubricants market.
Tangmanuswong joined Chevron in 2008 and has since held leadership roles of increasing responsibility from Procurement, Supply Chain, Engineering, Asset Optimization, and Special Projects across Asia-Pacific markets. He most recently served as General Manager and Country Chairman of Chevron (Cambodia) Limited, where he oversaw significant improvements in terminal operations, product supply, distribution, and marketing.
“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 a spirit of collaboration. Together, we will challenge limits, seize new opportunities, and shape a successful, sustainable future.” Tangmanuswong succeeds Billy Liu, who led CPI for nearly five years, and is now moving on to a new role at Chevron’s headquarters in Houston.
Liu celebrated his successor’s appointment, saying, “Khun Bon’s and my terms as general managers of the Cambodian and Philippine offices have coincided. In that time, I saw his ability in delivering 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 underscores Chevron’s commitment to strengthening its Philippine operations and supporting the country’s growing demand for reliable and cleaner energy solutions.
