Rubia Works 4000 10W-40

Description

Rubia Works 4000 10W-40 is especially suitable for engines used in Off-Road activities (quarries, construction, mining, railroads…) requesting API CK-4 or CJ-4 level.
Thanks to its numerous approvals, it can be used also in “On-road” truck engines. This lubricant withstands very long working hours under severe conditions and high load, with dust and heat.
Rubia Works 4000 10W-40 is recommended for engines equipped with Exhaust gas after-treatment system meeting EURO Stage V (or US EPA Tier 4F) Standard and, for On-Road, EURO 6, as well as previous standards.
Rubia Works 4000 10W-40 is particularly suitable for American, European and Japanese engines.
Thanks to its specific “Low SAPS” technology (Low content of Sulphated Ash, Phosphorus and Sulphur), Rubia Works 4000 10W-40 is designed for the latest Diesel engines equipped with post-treatment systems, such as Diesel particulate filters (DPF) or DENOX catalysator

Rubia Works 4000 10W-40 exhibits excellent thermal stability ensuring efficient lubrication of hot engine pieces during severe and long working periods.
Rubia Works 4000 10W-40 has been especially reinforced in viscosity stability under shearing and oxidation resistance (much higher than simple API CK-4), providing the possibility for the end user to reach or to exceed the maximum manufacturer’s drain interval recommendation, even under severe working conditions with bad Fuel quality or with Bio-Diesel fuel.
Furthermore, it’s 10W-40 viscosity grade allows the end user to start the engine at very low temperature. The advanced “Low SAPS” formulation of Rubia Works 4000 10W-40 helps prevent the clogging of the Diesel Particulate Filter (DPF) and extends the post-treatment system durability.
