Castrol GTX ECO

To help contribute to a lower carbon future, Castrol is exploring new ways to manufacture engine oils that can help significantly reduce the carbon footprint of its products.

For example, Castrol GTX ECO products use an innovative base oil blend that is made of at least 50% re-refined oil with the remainder from virgin oil, delivering a minimum 10% carbon dioxide (CO₂) reduction ¹. 

To make Castrol GTX ECO, used oil is put through a rigorous re-refining process to return it into as good as new base oils.  Castrol GTX technology is then added to fortify the oil. This creates a high performance product that can help to extend engine life while reducing the CO₂ that is produced throughout the oil’s life cycle.

BP piloted GTX ECO in India in 2016-17 and launched two new variants of Castrol GTX ECO made with 100% re-refined oil in the US in 2018.

¹ In the case of the Castrol GTX ECO 15W-40 product released in India, the 10% CO2 reduction is based on 2015 Life Cycle Assessment when compared with Castrol GTX Diesel 15W-40.
