A. Castrol Hyspin AWS 150 is designed for severely stressed hydraulic systems requiring a high level of anti-wear performance. The ISO VG 150 viscosity is the heaviest grade suited to heavily loaded industrial circulation systems, large gearcase applications and hot-ambient hydraulic operation.
A. Castrol Hyspin AWS 150 is supplied at ISO VG 150 — the heaviest grade in the Castrol Hyspin AWS range.
A. Castrol Hyspin AWS 150 meets ISO 6743-4 HM; DIN 51502 and 51524 HLP; and ASTM D6158.
A. Yes, the Castrol Hyspin AWS range uses a zinc-containing anti-wear additive system.
A. Both are Castrol Hyspin AWS zinc-containing anti-wear hydraulic oils with the same classifications. AWS 100 is ISO VG 100 — the heavy-duty viscosity. AWS 150 (this product) is ISO VG 150 — the heaviest grade in the range, for the most heavily loaded circulation and hot-ambient applications.
A. Castrol Hyspin AWS 150 is a hydraulic/circulation oil. For dedicated industrial gearbox applications, a Castrol Alpha SP or Alphasyn industrial gear oil to ISO 12925 CKD / DIN 51517-3 is the correct selection — check the gearbox manufacturer's specification.
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.
