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.

Greyhound G-Premium 15W-40 Engine Oil CK-4 20L: Heavy-Duty Diesel Engines

15w-40 ck-4 engine oil application: trucks, buses, bakkies, 4x4s and vans; construction, mining, agricultural and industrial equipment; mixed fleets running both new low-emission and older diesel engines.

Greyhound G-Premium 15W-40 CK-4 is our top-tier heavy-duty diesel engine oil, engineered for the latest low-emission diesel engines. Moreover, it is fully backward compatible with API CJ-4, CI-4+, CI-4 and CH-4, so one oil covers your whole diesel fleet – from the newest DPF-equipped trucks to older workhorses. The 20L drum is the fleet and workshop workhorse – the most economical way to run API CK-4 protection across trucks, buses, plant and mining equipment.

15W-40 CK-4 Engine Oil for Modern Low-Emission Diesel Engines

API CK-4 is the current heavy-duty diesel category, developed for engines fitted with EGR, SCR and diesel particulate filter (DPF) exhaust systems. Blended with high-quality API Group II and Group III base oils and a modern additive package, Greyhound G-Premium 15W-40 CK-4 delivers stronger oxidation resistance, better shear stability and improved soot control than previous-generation CJ-4 and CI-4 oils. As a result, it protects turbochargers and aftertreatment systems, keeps particulate filters cleaner and supports extended drain intervals under severe operating conditions – high temperatures, heavy loads, stop-start cycles and extended idling. In addition, it is well suited to the modern Chinese trucks and equipment now common on South African roads, mines and construction sites – including Sinotruk, HOWO, Shacman, FAW, Foton, SANY, XCMG and LGMG – as well as European and American diesel engines from Mercedes-Benz, MAN, Volvo, Renault Trucks, Mack and Caterpillar.

Specifications: SAE 15W-40; API CK-4 (backward compatible with CJ-4, CI-4+, CI-4, CH-4); formulated to meet the requirements of Mercedes-Benz, MAN, Volvo, Renault Trucks, Mack and Caterpillar heavy-duty diesel engines; suitable for engines with EGR, SCR and DPF exhaust-gas aftertreatment; blended with high-quality API Group II and Group III base oils.

Current API CK-4 heavy-duty diesel specification – the latest low-emission category;
Fully backward compatible with API CJ-4, CI-4+, CI-4 and CH-4;
Safe for EGR, SCR and DPF-equipped engines – helps prevent particulate filter clogging;
Outstanding oxidation resistance and shear stability for long-drain performance;
Superior soot dispersal and wear protection for extended engine life;
Ideal for modern Chinese, European and American diesel trucks and equipment.
