Q 1. What transmissions and axles is Q8 Oils XG 80W-90 designed for?

A. Q8 Oils XG 80W-90 is specifically formulated for use in both axles and synchronised as well as non-synchronised manual transmissions — a dual-purpose fluid for commercial vehicle and heavy-duty service.

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 classifications does Q8 Oils XG 80W-90 meet?

A. Q8 Oils XG 80W-90 meets API GL-4 and GL-5; and SAE J2360.

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 XG 80W-90 carry?

A. Q8 Oils XG 80W-90 carries MAN M341 E; MAN M342 E; and ZF TE-ML 02B, 05A, 12L, 12M, 16B, 17B, 17H, 19B and 21A.

Q 7. Can Q8 Oils XG 80W-90 be used in both manual transmissions and rear axles?

A. Yes, Q8 XG 80W-90 is a universal gear and axle fluid meeting both API GL-4 (manual transmission) and API GL-5 (hypoid axle) requirements. Always check the equipment manufacturer's specification before substituting.

Q 8. What is SAE J2360?

A. SAE J2360 is a US military-derived heavy-duty automotive manual transmission and rear axle gear oil specification that consolidates the requirements of multiple US military specifications. SAE J2360 approval indicates the product has passed an extended series of laboratory and field tests beyond the basic API GL-5 requirements.

Q 9. What is the difference between Q8 XG 80W-90 and Q8 Oils T 35 80W-90?

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