Typical characteristics

Manufacturer's description

Cat DEO Cold Weather SAE 0W-40 is a synthetic diesel engine oil designed with an extremely stable formula for long-lasting engine protection over a wide temperature range, from -40°F (-40°C) to 104°F (40°C). It exceeds the performance requirements of Cat ECF-3 (Engine Crankcase Fluid Specification) and the API CJ-4 and API SM categories, and is backward compatible, making it well suited to mixed fleets of new and old machines; when used in engines with emissions-reduction technologies it delivers the full life and performance of aftertreatment components. Its special formulation flows readily at low temperatures, reducing startup wear and improving fuel economy in some applications, while outstanding thermal stability and oxidation resistance keep engine components cleaner. In testing it reduced piston deposits by more than 30% and gave more than 80% better viscosity control than ECF-3 standards, helping lower owning and operating costs through fewer oil changes and repairs. Typical characteristics include pour point -45°C, kinematic viscosity 87 cSt at 40°C and 15.2 cSt at 100°C, viscosity index 186, phosphorous 0.111% wt., sulfated ash 0.99% wt., sulfur 0.4% wt., TBN 7.8 and zinc 0.121% wt. Cat DEO Cold Weather can be used in heavy-duty diesel engines from manufacturers requiring API CJ-4, CI-4 PLUS/CI-4 or CH-4 oil, and in automotive gasoline engines requiring API SM oil; it also meets Cummins CES 20081 and Mack EO-N PP '03 OEM performance levels, and supports engines meeting 2007/2010 US on-highway emissions standards, Tier 4 (US), Stage IIIB/IV (EU) and Step 4 (Japan).

Applications

• Preferred diesel engine oil for low-temperature applications.
• Supports consistent emissions performance in engines fitted with aftertreatment devices (DPF, DOC, SCR, LNT) meeting the 2007/2010 on-highway standards (US), Tier 4 (US), Stage IIIB/IV (EU) and Step 4 (Japan).
• Suitable for mixed fleets: usable in heavy-duty diesel engines that recommend API CJ-4, CI-4 PLUS/CI-4 or CH-4 oil, and in gasoline engines recommending API SM oil.
• Recommended operating range: -40°C to 40°C, versus -10°C to 50°C for Cat DEO-ULS 15W-40 and -18°C to 40°C for Cat DEO-ULS 10W-30.

Performance & benefits

• Easier engine starts: excellent low-temperature performance eliminates hard starting.
• Reduced engine wear thanks to improved detergents that keep engine components cleaner.
• Minimized deposits: reduced oxidation breakdown and thermal degradation limit the formation of sludge and varnish.
• Full component life: specially designed additives protect the engine and extend the life of aftertreatment system components.
• Supports consistent emissions performance over the life of the aftertreatment system.
• Extended drain intervals are possible when regular S•O•SSM oil analysis is used.
