  • Approved by Scania, RVI, ZF, and meets API GL-5 and MT-1 standards

Global Product Code: 001D8285



Application:

Shell Spirax S3 AS 80W-140 is a high-performance axle and transmission oil designed for use in a wide range of automotive axle units subjected to heavy-duty conditions. It is formulated with advanced additives and high-quality base oils to enable extended drain capability in specific applications. The oil is suitable for most modern heavy-duty axles with hypoid gears and is also recognized by certain manufacturers for use in heavy-duty manual gearboxes where API GL-5 or MT-1 oils are specified.

Performance Features & Benefits:

  • Excellent Component Protection: Provides strong anti-wear, anti-rust, and oxidation stability to extend gear life under extreme conditions.
  • Superior Oxidation Stability: Exceeds enhanced oxidation requirements of the latest API gear oil standards, reducing sludge and deposit formation.
  • Enhanced Spalling Resistance: Formulated to protect against surface fatigue and gear pitting.
  • Improved Filterability: Specially developed for use in axles fitted with oil filtration units, maintaining optimum oil flow throughout extended drain intervals.

Main Application Areas:

  • Heavy-duty axles with hypoid gears requiring extended drain intervals
  • Non-synchronised and some synchronised heavy-duty manual gearboxes where API GL-5 or MT-1 oils are allowed (not suitable for gearboxes requiring GL-4 oils)
  • Other automotive transmission systems operating under high-speed/shock load, high-speed/low torque, or low-speed/high torque conditions

Specifications & Approvals:

  • API GL-5, MT-1
  • Scania STO 1:0
  • RVI (Recommended for latest heavy-duty axle P1370 applications)
  • ZF TE-ML 12E, 05A, 16C, 21A

Usage Instructions:

  • Follow manufacturer recommendations for oil type and drain intervals.
  • Do not use in manual transmissions requiring GL-4 oils.
  • Consult Shell Technical Helpdesk for applications not listed here.

Environmental & Safety Information:

  • Shell Spirax S3 AS 80W-140 is unlikely to present significant health or safety hazards when used properly and with good personal hygiene.
  • Avoid skin contact with used oil. Use gloves and wash thoroughly with soap and water after contact.
  • Do not discharge used oil into drains, soil, or water. Return used oil to an authorised collection point.
  • Safety Data Sheet (SDS) available via inquiry.
