Conventional Oil vs Synthetic Oil

When it comes time to get your oil changed, your technician may ask what kind of oil you want to use in your vehicle? They will probably mention conventional and synthetic oils. But what’s the difference? Which oil is better for driving around Worcester, Auburn, and Shrewsbury, MA?

To help drivers answer these questions, Harr CDJR has put together this page comparing synthetic and conventional oils. Give it a read to learn more!

What Does Oil in Your Vehicle do?

Conventional Oil vs Synthetic OilOil has two jobs in your vehicle. The first job is to lubricate your engine. Your vehicle’s engine is made of many moving parts, and those parts shouldn’t rub together. When oil circulates through your engine, it prevents these parts from rubbing together. If there is not enough oil, these parts will rub together, and over time, your engine will get damaged.

The second job of oil is to keep your engine cool. When your engine runs, it puts off heat. As oil circulates, it cools down your engine. Since it also keeps engine parts from rubbing together, it reduces any heat the engine might give off from potential friction.

What is the Difference Between Conventional Oil vs Synthetic Oil?

There are a few different types of engine oil, and some of the most common are conventional oil and synthetic oil.

Conventional oil is the most common type of oil. It is best for later-model, light-duty vehicles with a simpler engine design. This type of oil handles high temperatures well without breaking down and is often less expensive than other types of oil.

Synthetic oil is best for vehicles that have high-level performance and need a high level of lubrication. More complicated engines do well with this kind of oil. Synthetic oil can help improve fuel efficiency; however, it often costs more money than conventional oil.

Synthetic oil is often more resistant to oxidation and has a higher viscosity level, keeping friction and heat levels down. Some engines react poorly to the switch to synthetic oil, particularly if they are older model vehicles, so it is not ideal for every car.

Signs You Need an Oil Change

Signs You Need an Oil ChangeRegardless of what type of oil you go with, there are a couple of signs you can keep your eye out for that will tell you when you need your oil changed.
