All About Oil Change Service

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.

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!

Buick Service: Winterizing Your SUV

We expect so much out of our vehicles throughout the winter. After all, we still have our regular driving demands but are completing them in cold temperatures, snow, and ice. We can help you get your SUV ready with Buick service at Vaughn Chevrolet Buick GMC of Ottumwa.
Check Your Heater
It’s already chilly out, but we all know it’s just going to get worse. You want to make sure that your heater is in peak condition. Plus, you need to ensure that you can always quickly defrost your windshield.
Replace Your Windshield Wipers
You’re definitely going to have a hard time clearing your windshield if your wipers are worn or brittle. This is a great time to replace yours with a fresh set. You also want to fill up your windshield wiper fluid to help clear all that extra muck.
Top Off Your Fluids
The cold weather can seriously strain your vehicle. Topping off your fluids to ensure your vehicle works efficiently is essential. This includes motor oil, coolant, brake fluid, transmission fluid, and more.
Consider Snow Tires
Traction is crucial in the winter since the roads are often slick or snowy. We recommend upgrading your tires to winter tires because they are specially designed to conform to the road for better traction and handling. However, even all-weather tires are sufficient as long as they have sufficient tread depth.
Pack a Winter Safety Kit
A winter safety kit is crucial in case you end up trapped in the elements:
• Jumper cables
• Ice scraper and brush
• Sand or kitty litter
• First aid kit
• Blanket
• Snacks and bottled water
