In high-pressure industries like transport, agriculture, logistics, mining, and construction, engine performance is profit. And one of the most overlooked culprits eating away at that profit? Outdated engine oil.
If you're still relying on older API-grade oils like CI-4 or CJ-4, your business could be spending more on maintenance, downtime, and fuel than it needs to. Here's how to tell if your oil is doing more harm than good — and why Shell Rimula R4 L 15W-40 CK-4 is the smart upgrade.
one

You're Changing Oil Too Often
Frequent oil changes aren't just time-consuming — they're expensive. If you're still using older oils that degrade quickly under heat or stress, you're likely dealing with:
- Shorter drain intervals
- More workshop visits
- Labour and disposal costs
Shell Rimula R4 L 15W-40 CK-4 is formulated with advanced oxidation control, which allows for extended drain intervals — saving you both time and money
two

Your Engines Are Running Hot or Noisy
Older oils can break down under high-load or high-temperature conditions, leading to:
- Increased engine friction
- Noisy operation
- Reduced efficiency
Shell Rimula R4 L 15W-40 CK-4 is engineered for high-performance protection, even under South Africa's toughest conditions — from stop-start traffic to long-distance hauls in 35°C heat.

Repairs and Downtime Are Eating into Profits
Are you seeing an increase in:
- Camshaft wear?
- Turbocharger issues?
- Piston scuffing?
Outdated oils often don't provide the wear protection modern engines demand. That translates into premature part failures and costly downtime. Shell Rimula R4 L 15W-40 CK-4 offers up to 50% better wear protection compared to previous API categories — keeping your vehicles on the road, not in the shop.

Emissions System Failures Are Becoming Common
Many older API oils are not compatible with modern emissions systems like EGR, DPF, or SCR. This can lead to:
- Filter blockages
- Fault codes
- Expensive system replacements
Shell Rimula R4 L 15W-40 CK-4 oil is designed to protect and clean emissions systems, improving fuel economy and helping you stay compliant with local environmental standards
five

Your Oil Consumption Is Higher Than It Should Be
If you're topping up oil between service intervals, you're wasting product and money. Poor thermal stability in older oils leads to evaporation, breakdown, and increased consumption. Shell Rimula R4 L 15W-40 CK-4 maintains its viscosity and stability longer, reducing oil top-ups and giving your engines consistent protection throughout the service life.
What's the Solution?
It's simple:
Upgrade to Shell Rimula R4 L 15W-40 CK-4 — the smarter, tougher oil for South African engines.
✔️ Longer service intervals
✔️ Less wear and tear
✔️ Lower oil consumption
