RRBO addressed in latest code of practice: ATIEL

  • 19/12/25

European lubricants industry associated ATIEL has addressed use of Re-Refined Base Oils (RRBO) in automotive engine oils in its latest code of practice.

The 26th issue of its code of practice comes into effect today, and includes RRBO for the first time in engine oil formulations. Regarding API base oil grouping, ATIEL recommends RRBO is treated in the same way as virgin base stocks.

This represents ATIEL's effort to align European lubricants industry practices with resource efficiency and circularity principles, supporting the EU's Green Deal ambitions. By providing guidance for formulators and marketers, the new code is intended to aid continuous improvement in the development of engine lubricants.

Re-refined base oil stocks were largely available in Europe in December. A weaker economic outlook and plentiful availability of virgin grades of similar viscosity weighed on spot prices. Some suppliers issued discounts to spur sales before Christmas.

Argus-assessed Group I SN 150 re-refined base oil spot prices dropped by €15/t to €675/t across December.
