Marvell 10W40 CJ-4/SN/E9 Semi Synthetic Diesel Engine Oil (205L)

Product Overview

Marvell 10W40 CJ-4/SN/E9 Semi Synthetic Diesel Engine Oil is a high-performance heavy-duty lubricant designed for modern diesel engines requiring advanced protection, reduced emissions, high cleanliness and long service intervals. Formulated using high-quality semi synthetic base stocks and an advanced multifunctional additive system, this engine oil is engineered to withstand severe load, high temperature operation and harsh Australian working conditions.

This 10W40 viscosity grade offers excellent balance between cold-start fluidity and high-temperature film strength, ensuring consistent protection whether engines operate in urban stop-start delivery cycles, heavy transport haulage, mining machinery, agricultural equipment or off-highway machinery.

The 205-litre industrial drum packaging is ideal for workshops, fleet operators, transport depots, service centres and agricultural maintenance facilities with high-volume lubricant consumption.

Key Features & Benefits

1. Advanced Wear Protection

The semi synthetic formulation combined with a reinforced anti-wear additive package protects critical engine components such as camshafts, bearings, valve trains and turbocharger shafts. This provides long engine life even in high-load, high-temperature environments such as long-haul transport and mining equipment.

2. Excellent Soot Control & Cleanliness

Marvell 10W40 CJ-4/SN/E9 provides strong dispersancy that maintains soot in suspension, preventing sludge formation, bore polishing and deposits. This protects engines operating under high EGR soot-loading conditions, providing cleaner pistons and improved long-term performance.

3. Optimised for Low-Emission Engines

This oil supports modern low-emission diesel technologies. Its low-SAPs formulation ensures reduced sulphated ash, phosphorus and sulphur levels, helping prevent after-treatment blockage and extending the life of DPF, SCR and catalytic converters.

4. Stable Viscosity for High Temperature Operation

The semi synthetic base oil blend gives excellent thermal and oxidation stability. The oil remains within its viscosity grade under extreme heat, ensuring consistent lubrication and preventing breakdown that can occur under sustained heavy loads.

5. Enhanced Cold-Cranking Performance

The 10W rating ensures rapid oil circulation during cold starts, reducing start-up wear. This is particularly important for fleet vehicles, agricultural machinery and diesel engines that start under low-temperature conditions.

6. Reduced Oil Consumption

The highly stable base oils reduce evaporation and burn-off, lowering oil consumption and increasing operational cost efficiency for fleet operators.

7. Strong Detergent System for Clean Engines

High-detergency chemistry keeps injectors, pistons and ring lands clean, maintaining fuel efficiency and performance over long service intervals.

8. Suitable for Mixed Fleets

Because of its dual API rating (CJ-4 for diesel and SN for petrol), this product can be used in mixed-fleet operations, reducing the need for multiple oil grades and simplifying workshop inventory.

9. Extended Drain Intervals

Under OEM-permitted conditions, Marvell 10W40 CJ-4/SN/E9 supports extended drain intervals thanks to its excellent oxidation stability and resistance to viscosity breakdown.

Applications

Marvell 10W40 CJ-4/SN/E9 Semi Synthetic Diesel Engine Oil is recommended for:

• Heavy-duty diesel engines in trucks, buses, construction, agricultural and mining equipment

• Engines fitted with EGR, SCR and DPF after-treatment systems

• Modern Euro IV, V and VI engines requiring low-SAPs CJ-4 oils

• Off-highway machinery such as excavators, loaders, graders and dozers

• Mixed fleets operating petrol and diesel vehicles

• Long-haul transport fleets requiring excellent thermal control and long oil life

• Turbocharged and naturally aspirated engines

• High-temperature industrial diesel engines requiring stable viscosity control

It is also backward compatible with older diesel engines requiring API CI-4, CH-4 or earlier performance levels.

Handling & Storage Advice

• Store in a cool, dry, well-ventilated area away from direct sunlight.

• Keep containers sealed when not in use to avoid contamination.

• Avoid storing above 60 °C or in freezing conditions.

• Use clean, dedicated dispensing equipment to prevent cross-contamination with other oils.

• Do not mix with oils of different performance categories unless verified compatible.

• Dispose of used oil and empty drums in accordance with local environmental regulations.

• Always refer to the Safety Data Sheet for guidance on handling, disposal, and first aid.

• Shelf life: Up to 5 years when stored in unopened drums under optimal conditions.
