Caterpillar DEO-ULS Cold-Weather
CAT DEO-ULS COLD WEATHER
Cat® ECF-3/API CJ-4 Engine Oil
SAE 0W-40
Cat DEO-ULS Cold Weather supports consistent emissions performance in engines equipped with aftertreatment devices designed to meet:
• 2007 / 2010 On-Highway exhaust emissions standards (US)
• Tier 4 (US)
• Stage IIIB/IV (EU)
• Step 4 (Japan)
Cat DEO-ULS is an excellent choice for mixed fleets because it can be used in heavy-duty diesel engines built by manufacturers that recommend API CJ-4, CI-4 PLUS/CI-4 or CH-4 classification oil as well as automotive gasoline engines that recommend API SM classification oil.
Cat® DEO-ULS™ Cold Weather is a synthetic diesel engine oil designed with an extremely stable formula tailored to provide long-lasting engine protection over a wide temperature range, -40°F (-40°C) to 104°F (40°C). The backwards compatibility of Cat DEO-ULS Cold Weather makes it well suited for mixed fleets of new and old machines. When used in engines equipped with emissions reduction technologies, Cat DEO-ULS Cold Weather delivers the full life and performance of aftertreatment components. Cat DEO-ULS Cold Weather exceeds the performance requirements of Cat ECF-3 (Engine Crankcase Fluid Specifi cation) and the API CJ-4 and API SM categories.
Cat DEO-ULS Cold Weather takes the trouble out of starting your engine when temperatures are very low. The special formulation flows readily at low temperatures, reducing startup wear and improving fuel economy in some applications. The outstanding thermal stability and oxidation resistance of Cat DEO-ULS Cold Weather keeps engine components cleaner, further reducing wear. In testing, Cat DEO-ULS Cold Weather was shown to reduce piston deposits by more than 30% and to have more than 80% better viscosity control than ECF-3 standards. These results demonstrate that Cat DEO-ULS Cold Weather will help lower your owning and operating costs through fewer oil changes and repairs.
• Easier Engine Starts - Excellent low temperature performance eliminates hard starts
• Reduced Engine Wear - Improved detergents keep engine components cleaner
• Minimized Deposits - Reduced oxidation breakdown and thermal degradation improves stability which minimizes the formation of deposits, sludge and varnish
• Full Component Life - Specially designed additives deliver superior engine protection while supporting consistent emissions performance and extending the life of after treatment system components
• Extended Drain Intervals - When regular S•O•S™ Oil Analysis is utilized, long oil life is possible
