Q 1. What machinery is Shell Spirax S4 CX 30 designed for?

A. Shell Spirax S4 CX 30 is for modern transmission, final drive, oil-immersed brake and hydraulic systems in off-highway earthmoving and mining equipment. SAE 30 is the standard powershift viscosity for warm-ambient service.

Q 2. Is Shell Spirax S4 CX 30 the same as Shell Donax TC?

A. Yes, Shell Spirax S4 CX 30 was previously named Shell Donax TC 30.

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 30 carry?

A. Shell Spirax S4 CX 30 carries ZF TE-ML 03C; and Allison C-4.

Q 6. What is the difference between Shell Spirax S4 CX 30 and Castrol Transmax Offroad 30?

A. Both are SAE 30 single-grade powershift transmission fluids for off-highway machinery. The Shell product carries ZF TE-ML 03C and Allison C-4. The Castrol product carries Caterpillar TO-4 plus ZF TE-ML 03C and Allison C-4. Verify the OEM approval needed against the equipment specification.

Q 7. Why are powershift fluids single-grade?

A. Powershift wet clutches require friction stability across the service life — multigrade additives (viscosity-index improvers) can shear and alter friction characteristics. Powershift fluids are therefore supplied as single grades (SAE 10W, 30 or 50).

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.
