TotalEnergies Rubia Optima 1100 15W-40 – Low SAPS Heavy Duty Diesel Engine Oil

TotalEnergies Rubia Optima 1100 15W-40 is a high-performance, low-SAPS heavy-duty diesel engine oil developed for the latest generation of on-road diesel engines while remaining backwards compatible with older diesel engines. Previously known as Rubia TIR 7900 15W-40, this advanced engine oil is designed to provide reliable protection under severe operating conditions.

The low-SAPS formulation is suitable for modern diesel engines fitted with exhaust after-treatment systems, including Diesel Particulate Filters (DPFs). Its advanced formulation helps protect these systems while providing excellent engine cleanliness, wear protection and oxidation resistance.

Rubia Optima 1100 15W-40 is also designed to help simplify fleet lubrication requirements, making it suitable for mixed-brand commercial vehicle fleets where a single high-performance engine oil can cover a wide range of applications.
