Typical characteristics

Manufacturer's description

Cat DEO (Diesel Engine Oil) SAE 15W-40 is a heavy-duty diesel engine oil for the Asia Pacific, Europe and CIS markets, developed, tested and approved by Caterpillar to meet the same standards as all Genuine Cat Parts. It is recommended for Tier 3 and prior engines without aftertreatment systems, for heavy-duty diesel engines from other manufacturers that call for API CI-4 and prior oils, and for automotive gasoline engines requiring API SL oils; it is used as standard factory-fill for Cat engines. Cat DEO resists oxidation and prevents piston and ring deposit buildup for increased engine life, has been thoroughly tested in Cat diesel engines including those running on high-sulfur fuel, and offers improved soot control and enhanced shear stability that maintain proper viscosity for longer. Typical 15W-40 characteristics include a flash point of 225°C, density 0.869 g/ml, pour point -36°C, kinematic viscosity 110.20 cSt at 40°C and approximately 15.5 cSt at 100°C, viscosity index 136, sulfated ash 1.1% wt., TBN 9.2, zinc 0.129% wt. and phosphorous 0.112% wt. The 15W-40 grade meets or exceeds API CI-4/CH-4/SL, Caterpillar ECF-2, ACEA E7-16, and China GB 11122-2006 CI-4/CH-4 / GB 11121-2006 SJ/SL; it can also be used in engines requiring Cummins CES 20077/76/72/71, Mack EO-N/EO-M/EO-M PLUS, MAN 3275-1, MB 228.3, MTU Oil Category 2, Renault RLD-2, and Volvo VDS-2/VDS-3.

Applications

• Tier 3 and prior diesel engines without aftertreatment systems.
• Heavy-duty diesel engines from other manufacturers that recommend API CI-4 or prior classification oils.
• Automotive gasoline engines requiring API SL classification oil.

Performance & benefits

• Increased engine life: resists oxidation and prevents deposit buildup on pistons and rings.
• Proven performance, tested thoroughly in Cat diesel engines for excellent engine life across all applications, including with high-sulfur fuels.
• Long-lasting protection: improved soot control and enhanced shear stability maintain proper viscosity over longer operating periods.
• Used as standard factory-fill for Cat engines.
