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.
It0 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.
It 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

It exhibits excellent thermal stability ensuring efficient lubrication of hot engine pieces during severe and long working periods.
It 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 helps prevent the clogging of the Diesel Particulate Filter (DPF) and extends the post-treatment system durability.
