For fleets operating in extreme climates or subject to severe duty cycles, the investment in synthetics often translates to lower maintenance costs and longer engine life. Sulfated ash content, a byproduct of additive combustion, can poison the catalysts within Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) systems.
Understanding Heavy Duty Diesel Engine Oil Contamination Risks
Selecting an inappropriate viscosity can lead to increased fuel consumption or inadequate protection during peak loads. Contamination during the handling process is a common cause of premature engine wear, even with premium lubricants.
Benefits of Synthetic Formulations Conventional mineral oils remain a viable option, but synthetic alternatives offer distinct advantages for demanding applications. A designation like 15W-40 indicates the oil's flow characteristics at low temperatures (W) and its high-temperature viscosity.

Lower winter numbers ensure easier cold starts, while the higher number guarantees a stable film strength during operation. They also offer enhanced cold-flow properties and superior fuel economy over the life of the oil.
