Shell Spirax S4 CX 10W (formerly Shell Donax TC 10W) is a high-performance off-highway transmission and hydraulic oil designed to provide operators with reliable operation across the equipment service life. The product meets the demanding requirements of modern transmission, oil-immersed brake and hydraulic systems fitted to off-highway earthmoving and mining equipment.

The SAE 10W single-grade viscosity is the lighter powershift transmission viscosity for cold-climate or cool-ambient powershift operation in off-highway machinery.

Approvals and performance levels include ZF TE-ML 03C; Allison C-4; and SAE J300.

Shell Spirax S4 CX 10W is also available in a 209-litre drum (PRD00004026) for workshop bulk supply.

The 20-litre pack format is suited to single-machine top-up and small workshop service. Store sealed in the original packaging, in a clean, dry area away from extremes of temperature, to preserve product performance over its shelf life.

Shell Spirax S4 CX 10W is designed to provide operators with trouble-free operation and maximum reliability for the lifetime of the equipment, it meets the demanding requirements of modern transmission, oil-immersed brake and hydraulic systems fitted to heavy-duty off-highway equipment.

Technical

Q 1. What machinery is Shell Spirax S4 CX 10W designed for?

A. Shell Spirax S4 CX 10W is designed for modern transmission, oil-immersed brake and hydraulic systems in off-highway earthmoving and mining equipment. The SAE 10W viscosity suits cold-climate or cool-ambient powershift operation.

Q 2. Is Shell Spirax S4 CX 10W the same as Shell Donax TC?

A. Yes, Shell Spirax S4 CX 10W was previously named Shell Donax TC 10W.

Q 3. What is an OEM Specification?

A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.

Q 4. What is an OEM Approval?

A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.

Q 5. What OEM manufacturer approvals does Shell Spirax S4 CX 10W carry?

A. Shell Spirax S4 CX 10W carries ZF TE-ML 03C; and Allison C-4.

Q 6. Why is Shell Spirax S4 CX 10W a single-grade viscosity?

A. Powershift transmission fluids in the off-highway CAT TO-4 class are typically supplied as single-grade SAE 10W, 30W or 50W — the absence of viscosity-index improvers gives the friction stability required for powershift wet-clutch operation.

Q 7. What is the difference between Shell Spirax S4 CX 10W and CX 30?

A. Both are Shell Spirax S4 CX off-highway transmission, brake and hydraulic oils with the same approvals. CX 10W (this product) is the lighter single-grade for cold-climate operation. CX 30 is the heavier single-grade for general powershift service in warm conditions.

Q 8. What is an API/ACEA classification?

A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.
