When it comes to vehicle maintenance, few things are as important as oil change service. It helps to keep your vehicle working efficiently. We’re diving into all the details at Vaughn Chevrolet Buick GMC of Ottumwa. 

What Does Engine Oil Do?
Engine oil lubricates engine parts. It reduces friction, which helps minimize heat. It also helps keep your engine clean, which limits abrasive wear. As it does these jobs, it prolongs engine life.

Why Do You Need Oil Changes?
As motor oil ages, it thickens and loses its ability to flow freely. Then, it won’t protect your engine like it should. It will also force your engine to work harder than necessary, diminishing your performance and fuel efficiency.

How Often Should I Get an Oil Change?
Each vehicle (and driver) has different maintenance demands. Your owner’s manual will include a detailed description of the service you need and how often. Remember, you will need maintenance more often than the recommended timeline if you have harsh driving conditions.

What are Considered Harsh Driving Conditions?
Some drivers need maintenance more often than others, depending on their driving conditions and habits. These factors include:

• Frequently taking short trips
• Driving in dusty or muddy conditions
• Mountainous driving
• Driving in extreme temperatures
• Frequently towing or hauling heavy loads

What Type of Oil Do I Need?
Many GM vehicles need synthetic oil. It is a premium oil typically recommended for luxury and performance vehicles. Check your owner’s manual to see the specific recommendation for your car or SUV.

Schedule an Oil Change in Ottumwa, IA
When you need an oil change, it’s best to leave it to the professionals. That’s where our trained and certified technicians come in. Contact Vaughn Chevrolet Buick GMC of Ottumwa to schedule an oil change today!
