Renault and Castrol launch Re-Refined Base Oils range
Renault Group and Castrol have together announced the launch of their new co-branded Renault Castrol GTX range formulated with Re-Refined Base Oils (RRBO).
With this launch, Renault Group says it is the first automotive manufacturer to introduce this advanced technology to its latest engine oil specifications.
Starting with RN17 (5W-30) now available across the European dealer network, it addresses over 50 per cent of Renault Group vehicles in use in Europe.

Combined with RN700 and RN710 already launched and to be followed by RN720 and AN2022 in 2026, Renault Group will be the only carmaker to offer a full range of premium engine oils for all its models, formulated to include RRBO.
Used oils are re-refined with advanced technology to meet a standard equivalent to that of virgin oil. Combined with its expertise, Castrol says these oils “satisfy or surpass” Renault Group’s technical requirements while “maintaining engine protection, performance, and warranty coverage”.
With an estimated 13-24 per cent lower carbon footprint reduction, Renault Group says it decided to exclusively propose these premium oils to its customers as”a clear commitment to a more circular automotive industry”. It is also said to help enable used oil recycling, reduces waste, uses less crude oil, and helps lower Scope 3 emissions.
“This launch makes Renault Group the first OEM to provide its entire recent vehicle range with next-generation lubricants formulated with re-refined base oil,” said François Delion, vice president global after-sales at Renault Group. “It’s a true demonstration that sustainability can go hand-in-hand with uncompromising performance and quality, over the complete lifecycle of the vehicle.”
“By co-engineering these products, we’re helping Renault Group meet customer needs today and tomorrow with high-performance, lower carbon, more circular lubricants for the automotive sector,” added Slawek Radon, vice president business development and partnerships at Castrol.
