In demanding industries such as transport, logistics, agriculture, construction, and mining, engine reliability is non-negotiable. But if you're still relying on outdated API-grade oils like CI-4 or CJ-4, you could be spending more than you realise on maintenance, repairs, and downtime.
Here are five signs your engine oil could be eating into your operating budget - and why upgrading to Shell Rimula R4 L 15W-40 CK-4 might be the smart solution.
You’re changing oil too often
Older-generation engine oils tend to degrade faster under stress and heat, resulting in shorter drain intervals, more workshop visits, and rising labour and disposal costs. Shell Rimula R4 L 15W-40 CK-4 is formulated with advanced oxidation control, enabling longer oil life and extended drain intervals - saving time and money.
Your engines are running hot or noisy
If engines are running louder or hotter than usual, your oil might not be holding up under load. When oil breaks down, it leads to increased engine friction and reduced efficiency. Engineered for high-performance protection, Shell Rimula R4 L 15W-40 CK-4 performs even under the most demanding South African operating conditions.
Repairs and downtime are becoming routine
Turbocharger issues, camshaft wear, and piston scuffing are signs that your oil isn't providing sufficient wear protection. Shell Rimula R4 L 15W-40 CK-4 offers up to 50% better wear protection than previous API categories, keeping vehicles on the road longer and reducing unplanned maintenance.
Emissions system failures are becoming more common
Many older oils aren’t compatible with emissions systems such as EGR, DPF, or SCR. The result? Filter blockages, fault codes, and costly system replacements. Shell Rimula R4 L 15W-40 CK-4 is designed to support modern after-treatment systems, helping operators remain compliant and reduce fuel consumption.
Oil consumption is higher than it should be
If oil top-ups are becoming more frequent, it may be due to poor thermal stability. Older oils are more prone to evaporation and breakdown under heat. CK-4 oils like Shell Rimula R4 L maintain viscosity and protect engines over longer intervals, improving overall oil economy.
Why upgrade?
Shell Rimula R4 L 15W-40 CK-4 offers a range of advantages, including extended service intervals, reduced oil consumption, and enhanced wear protection. It is designed to be compatible with emissions systems and is suitable for use in both new and older engines.
