THE FLOW — HOW IT CONNECTS

Refining as the base,
extending into a range of businesses

GS Caltex refines crude oil into gasoline, diesel, jet fuel and a wide range of other petroleum products.

Naphtha, LPG, off-gas and unconverted oil from the refining process become feedstock for the petrochemical and base oil businesses, and go on to become materials and products for industry and everyday life.
