Can I use a 5W-40 engine oil if my owner's manual recommends 5W-30?

In many cases yes, but it is best to follow your vehicle manufacturer's specification. The 40 indicates a slightly thicker oil at operating temperature; check that the oil still meets the API/ACEA and OEM approvals listed in your manual, or contact our team for advice on your specific vehicle.

What is the difference between hydraulic HM and HV grade oils?

HM oils are anti-wear hydraulic oils for systems operating at relatively stable temperatures, while HV oils have a higher viscosity index, meaning they maintain more consistent viscosity across a wider temperature range, making them better suited to outdoor or variable-temperature applications.
