The Difference Between Conventional and Synthetic Oils

Car Care

Understand the Basics of Motor Oil

A lot of questions can arise when it comes to choosing the right motor oil for your car, truck, or SUV. What is the advantage of synthetic? Does my new truck take conventional oil? At what point do I need to switch to high-mileage? Understand the basics of motor oil to help you answer these questions.


Conventional Oil

High-Mileage Oil

Synthetic Oil

Conventional oil is made to ensure that it has the proper breakdown resistance, heat tolerance, and viscosity (thickness and fluidity) that engines require. For most vehicles, conventional oil is sufficient to get the job done. Depending on your application, stepping up to a more robust motor oil may be the right solution.     High-Mileage oil is meant for vehicles that have over 75,000 miles on the odometer. High-mileage oil helps to protect seals and prevents oil evaporation. High-mileage, high-performance vehicles, however, would benefit from using a synthetic oil as opposed to high-mileage.     Synthetic or "full synthetic" oil is made specifically to provide the highest level of lubrication in all temperatures, which results in better overall engine protection. Synthetic oil has superior cleansing properties which help to keep your engine cleaner.
