Q 1. What transmissions is Q8 Oils T 35 80W-90 designed for?

A. Q8 Oils T 35 80W-90 is developed for synchromesh manual transmissions — commercial vehicle and heavy-duty manual transmissions specifying an API GL-4 SAE 80W-90 gear oil.

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 35 80W-90 meet?

A. Q8 Oils T 35 80W-90 meets API GL-4.

Q 4. 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 5. 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 6. What OEM manufacturer approvals does Q8 Oils T 35 80W-90 carry?

A. Q8 Oils T 35 80W-90 carries MAN M341 E; John Deere JDM J11 and JDM; and ZF TE-ML 02B, 08, 16A, 17A and 19A.

Q 7. What is the difference between Q8 Oils T 35 80W-90 and Q8 XG 80W-90?

A. Both are Q8 SAE 80W-90 gear oils. Q8 Oils T 35 (this product) is API GL-4 only — for synchromesh manual transmissions. Q8 XG is the universal API GL-4/GL-5 fluid for both manual transmissions and hypoid axles, with the higher-EP additive system.

Q 8. What is the viscosity index of Q8 Oils T 35 80W-90?

A. Q8 Oils T 35 80W-90 has a viscosity index of 99 — indicating its resistance to viscosity change with temperature.
