Key Components
Base Oil: High-quality Group II or Group III base oils provide excellent thermal stability and oxidation resistance.
Additives: Accel-DX uses advanced detergents, dispersants, anti-wear agents, and antioxidants to protect critical engine components and ensure cleanliness.
Viscosity Modifiers: These ensure that the oil maintains its optimal viscosity across a wide range of temperatures, enhancing cold start performance and protecting against thermal breakdown.
Benefits of Accel-DX
1. Superior Wear Protection
One of the most critical functions of any engine oil is to protect engine components from wear. Accel-DX Diesel Engine Oil is formulated with anti-wear additives that create a protective layer on metal surfaces, reducing friction and preventing direct metal-to-metal contact. This is particularly important in heavy-duty engines that operate under high loads and pressures, where even minor wear can lead to significant damage over time.
2. High Oxidation Stability
Heavy-duty engines often operate at high temperatures for extended periods, which can cause oil to oxidize and break down. Oxidation leads to the formation of sludge and varnish, which can clog engine components and reduce overall efficiency. Accel-DX Diesel Engine Oil is formulated with antioxidants that provide excellent resistance to oxidation, ensuring that the oil retains its performance characteristics for longer periods and reduces the need for frequent oil changes.
3. Enhanced Soot and Particulate Control
Diesel engines produce higher levels of soot and particulates than gasoline engines. If left unchecked, these contaminants can accumulate in the oil and cause increased engine wear. Accel-DX Diesel Engine Oil contains advanced dispersants that prevent soot and particulates from clumping together, ensuring that they remain suspended in the oil and are carried away by the filtration system. This helps maintain engine cleanliness and prevents abrasive wear.
4. Excellent Viscosity Control
Maintaining the correct oil viscosity is critical for ensuring optimal engine performance, particularly in extreme temperature conditions. Accel-DX Diesel Engine Oil is designed to maintain its viscosity across a wide range of temperatures, ensuring reliable cold start performance in winter and excellent thermal stability in hot conditions. This viscosity control helps reduce engine friction, improve fuel efficiency, and extend the life of the engine.
5. Extended Drain Intervals
Frequent oil changes can be costly and time-consuming, especially for fleets of heavy-duty vehicles. Accel-DX Diesel Engine Oil is designed to provide extended drain intervals without compromising on protection or performance. Its high resistance to oxidation and thermal degradation means that the oil can remain in service for longer periods, reducing maintenance costs and vehicle downtime.
6. Fuel Efficiency Improvements
Reducing engine friction and maintaining optimal viscosity are key factors in improving fuel efficiency. Accel-DX Diesel Engine Oil is formulated to minimize friction between moving parts, which not only reduces wear but also helps improve fuel economy. For heavy-duty fleets, even small gains in fuel efficiency can result in significant cost savings over time.
