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.

Semi-Synthetic

Semi-synthetic engine oil blends synthetic and mineral base stocks to sit between conventional mineral oils and full synthetics on both performance and price.

It is a practical choice for higher-mileage petrol and diesel engines, light commercial fleets and vehicles running in demanding local conditions where a full synthetic is not specified. The synthetic component improves oxidation stability and cold-start flow compared with a straight mineral oil, while the detergent and dispersant additives keep pistons clean and hold soot in suspension. Common grades are 10W-40 for petrol and light diesel, and 15W-40 for heavier diesel duty.

Semi-synthetic engine oil should still be matched to the API or ACEA service level in the vehicle handbook, and drain intervals kept to the manufacturer schedule. Packs run from 1L up to 210L drums.
