RUBIA WORKS 4000 15W40

APPLICATIONS

Rubia Works 4000 15W-40 is especially suitable for engines used in earthmoving activities (quarrying, construction,
mining, road transport, railway traction and power generating units) requesting API CK-4 or CJ-4 level. Furthermore,
thanks to its numerous approvals, it can be used also in “On-road” truck engines. This lubricant withstands very long
working periods under severe conditions and high load, with dust and heat.

Rubia Works 4000 15W-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 15W-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 15W-40 is designed for the latest Diesel engines equipped with post-treatment systems, such as Diesel particulate
filters (DPF) or DENOX catalysator

PERFORMANCES & BENEFITS

Rubia Works 4000 15W-40 is formulated using advanced technology base oil together with robust additive formulation
that provide enhanced oxidation resistance & lubrication performance.

• Rubia Works 4000 15W-40 exhibits excellent thermal stability ensuring efficient lubrication of hot engine pieces
  during severe and long working periods.
• Rubia Works 4000 15W-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.
• The advanced “Low SAPS” formulation Rubia Works 4000 15W-40 helps prevent the clogging of the Diesel
  Particulate Filter (DPF) and extends the post-treatment system durability.
