Q 1. What axles is Q8 Oils T 45 LS SAE 90 designed for?

A. Q8 Oils T 45 LS SAE 90 is designed for limited-slip differentials in heavy-duty, performance car, 4x4 and commercial vehicle applications where API GL-5 LS-specification axle oil is required.

Q 2. 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.

Q 3. What performance classification does Q8 Oils T 45 LS SAE 90 meet?

A. Q8 Oils T 45 LS SAE 90 meets API GL-5 LS — the limited-slip variant of the API GL-5 axle oil specification.

Q 4. Is Q8 Oils T 45 LS SAE 90 approved for ZF?

A. Yes, Q8 Oils T 45 LS SAE 90 carries ZF TE-ML 05C, 12C, 16E and 21C approvals.

Q 5. Why does a limited-slip differential need a special oil?

A. The clutch packs inside an LSD generate friction during operation. Without specific friction-modifier additives, the clutch can shudder or chatter — particularly in cold conditions or low-speed turns. Q8 Oils T 45 LS contains the friction modifiers needed for smooth LSD operation.

Q 6. What is the difference between Q8 Oils T 45 LS and Q8 Oils T 55?

A. Both are Q8 API GL-5 axle oils. T 45 LS (this product) is the limited-slip variant (SAE 90) for LSD axles. T 55 is the standard non-LSD axle oil (SAE 85W-140) for general heavy-duty axle service.

Q 7. 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 8. 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.
