Caltex and Puma service stations are owned by the US corporation Chevron. Chevron runs natural gas extraction and pipelines off the shore of Palestine/Israel, making it a major partner in Israeli energy apartheid, the military blockade on Gaza, and the illegal exploitation of Palestinian land and resources. Chevron are a global BDS target. Don’t fill up at Caltex or Puma service stations.
