For many years, 15W-40 had been the most common viscosity for diesel motor oils used in trucks. It provides a good high temperature protection and can be formulated from conventional base stocks or synthetics.
In recent years, a number of oil companies have introduced thinner 5W-40 diesel oils – not only for cold weather operation, but also for year-round use. Most of the 5W-40 diesel oils are a synthetic-blend or a full synthetic to achieve the cold flow characteristics needed for easy starting. Other cold weather diesel oils include 0W-30, which is formulated for subzero arctic-type conditions.
