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.

4 Stroke Engine Oil

4 stroke engine oil is used in motorcycles, quad bikes, lawnmowers, generators, pumps and small air-cooled engines where the oil circulates in a sump rather than being burned with the fuel.

Motorcycles need particular attention. Most bikes share one oil between the engine, gearbox and wet clutch, so the oil has to lubricate the engine, survive gear tooth loading and still give the clutch enough friction to grip without slipping. That is what the JASO MA and MA2 ratings cover, and it is why a fuel-economy car oil with friction modifiers can cause clutch slip in a motorcycle. Air-cooled engines also run hotter than car engines, so thermal stability matters more.

For garden and standby equipment, check the grade in the manual and change oil on hours run rather than by season. Available in 1L, 5L and 20L packs.
