Factory and Indoor Machinery (Purpose: Standard Industrial Use)
Product Series: Shell Tellus S2 MX 46 (formerly S2 M 46)
Fluid Type:

ISO HM / HLP
This fluid is optimized for stationary indoor equipment like injection molding machines, hydraulic presses, assembly lines, and factory machine tools. It is designed for environments where the temperature stays relatively constant. It contains high-quality anti-wear additives and Group II base oils but lacks the extra polymer additives needed for extreme outdoor weather changes.

Outdoor and Mobile Equipment (Purpose: Wide Temperature Variations)
Product Series: Shell Tellus S2 VX 46 (formerly S2 V 46)
Fluid Type: ISO HV / HVLP
This fluid is designed for heavy machinery operating outdoors, such as construction excavators, mining equipment, mobile cranes, and marine hydraulic systems. It has a high viscosity index, meaning the oil will not get too thick in freezing morning temperatures and will not become too thin under intense midday heat and heavy workloads.

Longest Life and Extreme Workloads (Purpose: Maximum Efficiency and Synthetic Performance)
Product Series: Shell Tellus S4 ME 46
Fluid Type: Synthetic Advanced HM
This is a top-tier synthetic hydraulic fluid meant for energy-saving goals and critical systems running 24/7 under high pressures. It reduces energy consumption through specialized friction modifiers and lasts up to 2 to 4 times longer than standard mineral oils, significantly cutting down on maintenance downtime in heavy industrial plants.
Environmental Protection
(Purpose: Biodegradable and Eco-Friendly Use)
Product Series: Shell Tellus S4 VE 46
Fluid Type: Biodegradable / HEES
This fluid is formulated for machinery operating in environmentally sensitive areas, such as near waterways, agricultural land, forestry zones, or construction sites with strict pollution regulations. If a leak occurs, the fluid breaks down naturally without toxic impacts on soil or water.

Zinc-Free Requirements (Purpose: Critical Components and Silver/Bronze Plated Pumps)
Product Series: Shell Tellus S3 M 46 or Shell Tellus S3 V 46
Fluid Type: Ashless / Zinc-Free Anti-Wear
Standard hydraulic oils contain zinc additives for wear protection, but zinc can chemically attack components containing silver or yellow metals found in certain specialized industrial pumps. The ashless S3 series uses alternative chemical chemistry to provide strong component protection without corroding sensitive metals.

Shell Tellus S3 68 
refers to a premium tier of hydraulic fluids featuring an ISO VG 68 thickness. The defining feature of the S3 tier is its advanced zinc-free (ashless) anti-wear technology combined with top-tier oxidation resistance.
Zinc-Free Chemistry:
Uses exclusive ashless technology to protect heavy-duty hydraulic pumps without depositing ash or causing corrosion in components that contain yellow metals or silver plating.
Extended Fluid Service: Offers significantly prolonged oil drain intervals, with the industrial version achieving a TOST oxidation life up to 7,500 hours, keeping systems clean and reducing component sludge.
Excellent System Efficiency: Ensures rapid air release, low foaming tendencies, and fast water separation to maximize power transfer efficiency and protect pumps against cavitation.
High Shear Stability (S3 V Series Only): The V series incorporates highly shear-stable viscosity index modifiers that prevent the fluid from breaking down or thinning out under severe mechanical stress.
Primary Applications:
Indoor Industrial Plant Equipment (S3 M / S3 MX): Optimally used in stationary manufacturing machinery, high-pressure injection molding machines, automated press lines, and systems operating under controlled ambient factory temperatures.
Outdoor Mobile Equipment (S3 V): Ideal for machinery operating in exposed outdoor areas with extreme climate changes, such as excavators, cranes, marine hydraulic systems, and mining setups.
