What should I consider when pricing out oil?

There are many factors to consider when purchasing oil for the engine of a car, including price, viscosity, desired mileage and oil quality. Although high-quality oils may come with a larger price tag, it is important to pick the right oil for a specific car's needs.

Typically, high-priced oils are usually of a higher grade than low-priced oils. Higher-priced oils usually have an API stamp of approval and a two-character service designation, which are beneficial for the functionality of the vehicle, according to Popular Mechanics. Although vehicles can function when low-quality oils are used, oils that are high in quality allow vehicles to run at their fullest potential.
