When to Replace Your Car’s Fluids

Service Maintenance | Woodbridge, VA

When it comes to maintaining your vehicle’s fluids, oil changes are just the beginning. Other critical fluids, like coolant and brake fluid, also need to be changed to help your car last longer and perform better. Here’s an overview of when you should replace your car’s fluids.

Motor oil

When it comes to changing your oil, the time frame will vary based on the kind of oil you use. Conventional oil needs to be swapped every 3,000 miles, synthetic blends can last up to 5,000 miles, and fully synthetic lubricants can go for 10,000 miles. That said, it’s still important to check your oil regularly to make sure it’s not dark or gritty.


When your car’s antifreeze gets old, it can corrode your vehicle’s gaskets and seals. That’s why it’s important to change the coolant about every three years.

Brake fluid

As time passes, brake fluid absorbs moisture, which can lead to rusting in your car’s brake lines. Don’t risk this critical part of your vehicle — have the brake fluid changed every two years.

When it comes to other fluids in your vehicle, consult your vehicle owner’s manual to learn more. While service intervals can vary based on how often you drive and the condition of your vehicle, you can always consult the experts at the Lustine Chrysler Dodge Jeep® Ram service center in Woodbridge, Virginia.
