A. Castrol Hyspin AWH-M 100 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 100 is supplied at ISO VG 100 — a heavy-duty grade in the Hyspin AWH-M range.
A. Castrol Hyspin AWH-M 100 meets ISO 6743-4; and DIN 51502 and 51524.
A. Both are Castrol Hyspin AWH-M anti-wear multi-purpose hydraulic oils with the same classifications. AWH-M 100 (this product) is ISO VG 100. AWH-M 150 (143C3A) is ISO VG 150 — the heaviest grade in the range. Select per the equipment manufacturer's required ISO VG grade.
A. Both are Castrol zinc-containing anti-wear hydraulic oils. Hyspin AWH-M (this product family) is the multi-purpose anti-wear range positioned for hydraulic and circulation service across heavier viscosity grades. Hyspin AWS is the standard anti-wear hydraulic range for mainstream hydraulic service.
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.
