Chinese trucks and equipment have become a familiar sight on South African roads, mines and construction sites. Sinotruk and HOWO tippers, Shacman side-tippers, FAW rigids, Foton bakkies and SANY, XCMG and LGMG machines now make up a growing share of working fleets — and they have one thing in common under the cab: a modern low-emission diesel engine that deserves the right oil. That oil is CK-4 engine oil, and Greyhound Lubricants has just launched its G-Premium 15W-40 CK-4 range in South Africa.
Why modern Chinese trucks need CK-4 engine oil
Newer Sinotruk, HOWO, Shacman and FAW models sold in South Africa run engines built for low-emission standards, many fitted with exhaust-gas recirculation (EGR), selective catalytic reduction (SCR) and diesel particulate filters (DPF). These systems are sensitive to the oil you use: the wrong oil can clog a particulate filter, shorten drain intervals and cost real money in downtime. API CK-4 is the current heavy-duty diesel category, developed precisely for these engines. It controls soot, resists oxidation at high temperatures and keeps aftertreatment systems clean — which is why CK-4 engine oil is the sensible default for any late-model Chinese truck or machine.
One oil for the whole mixed fleet
Most South African fleets are mixed: a few new DPF-equipped trucks alongside older workhorses. The good news is that CK-4 is fully backward compatible with API CJ-4, CI-4+, CI-4 and CH-4. In practice, that means one drum of Greyhound G-Premium 15W-40 CK-4 20L can service the new HOWO alongside the ten-year-old Mercedes-Benz, MAN or Volvo — simplifying stock, reducing the risk of misfuelling the wrong engine, and usually working out cheaper than running two oils.
What you get with Greyhound G-Premium 15W-40 CK-4
- Current API CK-4 heavy-duty diesel specification — the latest low-emission category;
- 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;
- Formulated to meet the requirements of Mercedes-Benz, MAN, Volvo, Renault Trucks, Mack and Caterpillar engines as well;
- Blended in Europe at ISO-certified plants — global quality at local pricing.
Which size should you buy?
The 20L is the fleet and workshop standard. The 5L suits diesel bakkies, 4x4s and vans — a single service fill for most turbo-diesel engines. The 1L and 500ml are the top-up sizes to keep in the cab. Because CK-4 engine oil is backward compatible, topping up an engine currently running CJ-4 or CI-4 is not a problem.
