About Base Oils

Section 1

We’re never satisfied with the status-quo. And when it comes to adding more value from our base oils production, we saw an opportunity and we delivered.

For the past 40 years, three of our downstream affiliates (LUBEREF, Motiva and S-Oil) have been major suppliers of quality Group I, Group II and Group III base oils. We’re collaborating to deliver new solutions that meet the needs of our customers – and the needs of evolving markets – with consistent quality and reliable supply from refineries located strategically around the world.

We’re integrating our product offering under a unified global brand family, Aramco Base Oils, to deliver a broad range of base oil products under the aramcoDURA, aramcoPRIMA, and aramcoULTRA brands.

Our customers can easily source the base oils that meet their existing specifications for finished lubricants from any one of our strategically located base oil facilities.

Get ready for a new base oils era from the largest crude supplier in the world.
