A. Q8 Oils Goya 320 is for enclosed industrial gear units, particularly heavily loaded medium-speed gearboxes in general heavy-duty industrial service where ISO VG 320 industrial EP gear oil is specified.
A. Q8 Oils Goya 320 is ISO VG 320 — a widely specified industrial gear oil viscosity for general heavy-duty enclosed gear service.
A. Q8 Oils Goya 320 meets DIN 51517 Part 3 (CLP industrial EP gear oil); and DIN 51354 (FZG gear-test).
A. Both are mineral-oil-based industrial EP gear oils at ISO VG 320 meeting DIN 51517 Part 3 (CLP). Either can typically be selected based on lubricant supply preference and gearbox manufacturer approval list.
A. Both are Q8 Oils Goya mineral industrial gear oils meeting DIN 51517 Part 3 (CLP). They differ only in viscosity grade: Goya 220 is ISO VG 220 for general heavy-duty service; Goya 320 (this product) is ISO VG 320 for heavier-duty medium-speed industrial gearboxes.
A. The FZG test (DIN 51354) is a standardised gear-oil bench test that evaluates load-carrying capacity by running a gear pair under increasing load until the gear teeth scuff. The FZG load stage rating is a key performance criterion for industrial EP gear oils.
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.
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.
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.
