A. Castrol Hyspin AWH-M 150 is designed for severely stressed hydraulic systems and circulating systems, suited to heavily loaded industrial circulation, large gearcase applications and hot-ambient operation where a thick hydraulic oil is specified.
A. Castrol Hyspin AWH-M 150 is supplied at ISO VG 150 — the heaviest grade in the Hyspin AWH-M range.
A. Castrol Hyspin AWH-M 150 meets ISO 6743-4; and DIN 51502 and 51524.
A. Both are Castrol anti-wear hydraulic oils. Hyspin AWH-M is the multi-purpose anti-wear range with a zinc-containing additive system for general industrial hydraulic and circulation service. Hyspin HVI is the high-viscosity-index ashless (zinc-free) range for severely stressed mobile hydraulic systems requiring wide-temperature viscosity stability.
A. Castrol Hyspin AWH-M 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. Yes, the heavier ISO VG 150 viscosity is positioned for warm- and hot-ambient operations and for systems generating high oil-film temperatures.
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.
