Questions & Answers

Is this a genuine original part?

This is a premium quality replacement fluid from Westway Oils, manufactured to meet or exceed ISO 11158 (HM) and DIN 51524 Part 2 standards.

How do I know if it is compatible?

Check your steering helm or trim pump reservoir cap or manual. If it specifies "ISO 10", "VG 10", or any of the cross-reference numbers listed above, this is the correct fluid.

Can I mix this with my existing hydraulic oil?

Yes, this mineral-based hydraulic oil is generally compatible with other mineral-based ISO 10 fluids. However, for best performance, a full system flush is recommended when changing fluid types.

Note: Please verify your manufacturer's required viscosity grade (ISO) before purchasing to ensure optimal system response.
