Purpose and Specifications

Shell Rimula R4 L 15W40 is a premium heavy-duty diesel engine oil designed for tough jobs in trucks, construction gear, and farm equipment. This 5-liter jug delivers energized protection with low-ash formula that guards exhaust systems like DPF filters, keeping your engine compliant and fuel-efficient even in modern low-emission vehicles.

It flows smoothly in cold starts down to -20°C and stays thick up to 150°C under heavy loads, slashing wear by up to 50% more than older oils for longer engine life. Backed by approvals like API CK-4, ACEA E9, Caterpillar ECF-3, Cummins CES-20086, Volvo VDS-4.5, and MB 228.31, it's versatile for Euro 5/6 trucks, off-road machines, and high-sulfur fuel areas.

• Key Benefits: Cuts deposits for cleaner pistons and valves, resists heat breakdown for 25 million+ km proven performance, boosts drain intervals to 50,000-100,000 km or 12-24 months depending on duty.
• Practical Edge: Lowers repair costs with superior acid control and sludge-free operation, ideal for mixed fleets.

When to Use / Replace?

Use in severe-duty diesels running hot hauls, dusty sites, or long distances. Perfect for daily drivers needing one oil for old and new engines. Replace every 40,000-60,000 km in heavy use or 12 months max; check dipstick monthly. Shelf life: 5 years unopened in cool, dry storage.

FAQ:

Is this oil good for my Euro 6 truck? Yes, its low-SAPS tech protects DPF and catalysts, maintaining emissions and efficiency.

Can I use it in older engines? Absolutely, meets backward-compatible specs for pre-2007 diesels too.

How often change for construction work? Aim for 30,000 km or 6-12 months in dusty, high-load conditions.
