If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

What does the W stand for in oil?

The short answer:The numbers represent the viscosity of the oil and the W stands for WINTER. The long answer:The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics.

Should I use thicker oil in a high mileage engine?

High mileage engines will need thicker oils. Thicker oils have additives such as conditioners, antioxidants, seal swells, detergents and friction additives that are engineered to take care of high-mileage engines. Gaskets, seals, and non-metal parts start decaying as an engine ages.
