Maintaining Proper Fluid Levels in Your Car: A Guide for Troy and Roseville Drivers

McInerney Auto Center • August 11, 2025

Keeping your vehicle in top condition isn’t just about oil changes and tire rotations—it’s also about the fluids that keep your engine, brakes, transmission, and cooling system running smoothly. For drivers in Troy and Roseville, where seasonal temperature swings and road conditions can take a toll, maintaining your car’s fluid levels is crucial to performance and safety.

Let’s break down why fluid checks are essential, what types of fluids need attention, and how often you should service them.

Why Fluids Matter in Vehicle Maintenance

Your car relies on several fluids that act as lubricants, coolants, hydraulic mediums, and cleansers. Neglecting these fluids can result in major repairs, decreased fuel efficiency, and even system failures.

By checking and maintaining fluid levels regularly, you can:

Extend your vehicle’s lifespan
Prevent overheating and breakdowns
Improve engine performance
Reduce repair costs
Drive safer through Michigan’s seasonal extremes

Top Fluids You Should Monitor

1. Engine Oil

Oil lubricates moving engine parts and prevents friction damage. If the level is too low or the oil is dirty, your engine can overheat or seize. Check it monthly and follow your vehicle’s oil change schedule (typically every 3,000–7,500 miles).

2. Coolant (Antifreeze)

Coolant prevents your engine from overheating in the summer and freezing in the winter. A low coolant level or an improper mix can lead to engine damage. Inspect levels at least twice a year—especially before winter and summer.

3. Transmission Fluid

This fluid ensures smooth shifting and protects transmission gears. For automatic transmissions, check the dipstick when the engine is warm and running. If it’s brown or smells burnt, it needs replacing. Most cars require a flush every 30,000–60,000 miles.

4. Brake Fluid

Brake fluid is essential for hydraulic braking systems. Low or contaminated fluid can lead to reduced braking power. It should be flushed every 2–3 years or as indicated by your vehicle’s manual. For drivers in stop-and-go Troy traffic, that interval may shorten.

5. Power Steering Fluid

This fluid allows you to steer smoothly with minimal effort. If steering feels stiff or you hear whining when turning, it may be low. Check it during every oil change or when symptoms appear.

6. Windshield Washer Fluid

While it doesn’t affect your car’s mechanics, having washer fluid topped off is essential for visibility during Michigan’s rainy springs, dusty summers, and slushy winters. Use washer fluid with antifreeze during cold months to avoid freezing.

When to Check Your Fluids

Here’s a quick maintenance timeline tailored for Troy and Roseville drivers:

Engine Oil - Check Monthly | Change Every 3,000–7,500 miles

Coolant - Check Before Summer/Winter | Flush Every 2 years

Transmission Fluid - Check Monthly | Flush Every 30,000–60,000 miles

Brake Fluid - Check Every 6 Months | Flush Every 2–3 years

Power Steering Fluid - Check Monthly | Top off as needed

Washer Fluid - Check Monthly | Top off as needed

Common Signs You’re Low on Fluids

If you experience any of the following symptoms while driving in Roseville or Troy, stop by McInerney Auto Center for a fluid inspection:

Overheating engine
Warning lights on your dashboard
Grinding or jerky transmission
Spongy or unresponsive brakes
Noisy or stiff steering
Reduced visibility due to dirty windshield

Why Fluid Maintenance is Especially Important in Michigan

In Michigan’s unpredictable climate, fluids can degrade or leak faster than in milder regions. Freezing winters, humid summers, and road salt can all affect fluid performance and system integrity.

For example:

Cold weather thickens oil and transmission fluid
Salt and grime contaminate brake and steering systems
Rapid temperature changes wear down seals and cause leaks

Fleet Vehicle Fluid Maintenance

If your business operates a fleet in the Troy or Roseville area—delivery vans, service trucks, Amazon vehicles—fluid checks should be part of your preventive maintenance program.
