Can synthetic-blend SAE 10W-30 or 10W-40 diesel engine oil help enhance the performance of my engine? Yes. Synthetic-blend SAE 10W-30 or 10W- 40 diesel engine oil, such as the new Shell Rotella® T5 Synthetic Blend Technology, may offer enhanced engine cleanliness and excellent wear protection in the hottest summer heat and the coldest winter freeze. This is possible through a combination of additives and synthetic-blend technology base oil. Synthetic-blend oil provides protection in critical areas by helping to control acid, deposits and wear. Synthetic-blend oil helps protect against acids which are formed as fuel burns. Wear control also contributes to engine life by keeping metal surfaces apart. Synthetic blends are often offered in lower viscosity grades such as SAE 10W-30 or 10W-40, compared to conventional SAE 15W-40 oil, so they will thicken less at colder temperatures. Quick oil flow in the engine at startup is important particularly in cold-climate conditions, as improved fuel and injection-system controls in newer diesel engines reduce the time it takes to start your engine. A synthetic-blend SAE 10W-40 or 10W-30 flows better than a conventional SAE 15W-40 diesel engine oil in a cold engine. Synthetic-blend engine oil also maintains its viscosity under high temperatures, providing strong protection under hot operating conditions. Increased fuel effi ciency is possible with synthetic-blend SAE 10W-30 engine oil, compared to conventional SAE 15W-40 engine oil, because it can increase fl ow capability, reducing the energy used to pump the oil through the engine. Shell Rotella® T5 Synthetic Blend Technology is an innovative heavy duty engine oil developed by Shell Lubricants designed to deliver fuel-economy savings, enhanced engine cleanliness and excellent wear protection. Shell Rotella® T5 Energized Protection™ oil meets API CJ-4 specifi cations for compatibility with the latest exhaust- emissions control systems. API CJ-4 synthetic-blend engine oils are suitable for use in most heavy duty diesel engines manufactured prior to 2007.
