A. Castrol Hyspin HVI 15 is intended for severely stressed hydraulic systems requiring a high level of anti-wear performance and fine filtration. The ISO VG 15 viscosity is the lightest grade, suited to cold-ambient hydraulic operations.
A. Castrol Hyspin HVI 15 is supplied at ISO VG 15 — the lightest grade in the Castrol Hyspin HVI range.
A. Yes, Castrol Hyspin HVI 15 is based on a carefully selected ashless (zinc-free) additive system.
A. Castrol Hyspin HVI 15 meets ISO 6743-4; and DIN 51502 and 51524.
A. Both are Castrol Hyspin HVI high-viscosity-index ashless anti-wear hydraulic oils with the same classifications. HVI 15 (this product) is ISO VG 15 — the lightest grade for cold-ambient operation. HVI 22 is ISO VG 22 — slightly heavier, for cool-ambient mobile-equipment operation.
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.
