Rubia Works 4000 0W-40 is specially formulated for engines equipped with exhaust gas after-treatment systems that comply with EURO Stage V and US EPA Tier 4F standards, as well as for road vehicles meeting EURO 6 and lower standards. This oil is perfectly suited for American, European, and Japanese engines.

Thanks to its low-SAPS technology (low content of sulfated ash, phosphorus, and sulfur), Rubia Works 4000 0W-40 is designed for modern Diesel engines equipped with after-treatment systems, such as diesel particulate filters (DPF) and DENOX catalysts.

Product advantages:

- Excellent thermal stability: Ensures optimal performance even at high temperatures.

- Extended oil change intervals: Exceeds the maximum recommended oil change intervals by manufacturers.

- Enhanced resistance: Maintains its viscosity against shear and oxidation.

- Particulate filter protection: Helps prevent clogging of the DPF.

- Increased durability: Prolongs the lifespan of after-treatment systems.
