Rubia Optima is the guarantee of real performance improvements in heavy-duty engines

The new Rubia Optima benefits from state-of-the-art “T.I.R Technology”, which refers to:

  • TotalEnergies protection: industry tested, Rubia products are put through numerous tests (Laboratory, bench and road tests) to achieve results that show excellent performance in oxidation stability, and protection against wear, deposits and soot.
  • International approvals: Rubia has a greater number of approvals as well as more advanced approvals than most other products in the market. This means multi-brand fleets require fewer products to meet crucial requirements of the most advanced engines in the market.
  • Reduced costs: Rubia offers better fleet cost savings with a full suite of TotalEnergies Fuel Economy engine oils that enables extended oil drain intervals.

TotalEnergies has worked closely with key Heavy-Duty Original Equipment Manufacturers (OEMs) to develop the new Rubia Optima oils with performances that surpass CK-4 oils including outstanding oxidation control, shear stability and oil aeration control.
