The Importance of Regular Differential Fluid Changes: What You Need to Know
Devin Kelley • February 20, 2025
Your car’s differential plays a crucial role in ensuring smooth and efficient power transfer from the engine to the wheels. Like other critical components, the differential requires regular maintenance, including fluid changes. Let’s explore why regular differential fluid changes are essential and what you need to know to keep your vehicle running smoothly.
What is Differential Fluid?
Differential fluid, also known as gear oil, lubricates the gears and bearings in the differential, reducing friction and preventing overheating.
Importance: Proper lubrication is vital for the differential’s longevity and performance.
Why Regular Changes are Crucial:
- Preventing Wear and Tear: Over time, differential fluid breaks down and becomes contaminated with metal particles.
Benefit: Regular changes ensure clean fluid is maintaining optimal lubrication, preventing excessive wear. - Avoiding Overheating: Old or degraded fluid can’t dissipate heat effectively.
Benefit: Fresh fluid helps regulate temperature, reducing the risk of overheating and damage. - Improving Performance: Clean differential fluid ensures smooth operation and efficient power transfer.
Benefit: This results in better vehicle handling and performance.
When to Change Differential Fluid:
Consult your vehicle’s owner manual for specific intervals, typically every 30,000 to 60,000 miles.
Tip! Regular inspections here at All-Star can also help identify when a change is needed.
Regular differential fluid changes are essential for maintaining your vehicle’s performance and preventing costly repairs. By keeping up with this simple maintenance task, you can ensure your differential remains in top condition, providing smooth and efficient power transfer for miles to come.

As the back-to-school season kicks off, most families are focused on new clothes, school supplies, and updated routines. But one thing many forget? Your car needs to be school-ready, too. Whether you’re driving your kids to school or a college student heading back to campus, your vehicle plays a big role in keeping your schedule on track. Your Back-to-School Vehicle Prep Checklist Here’s a simple, essential back-to-school car checklist to make sure your vehicle is ready for the busy school year ahead. 1. Check Your Tires Start the year with tires that are safe and road-ready. Check tread depth and look for uneven wear Ensure tire pressure matches your manufacturer’s recommendation Don’t forget the spare tire—it sh ould be inflated and in good shape Worn-out or overinflated tires can be a safety risk, especially with the morning and afternoon school traffic. 2. Test Your Battery If your battery is more than 3 years old, it’s a good idea to have it tested. The last thing you want is a car that won’t start on a busy school morning. Signs of battery trouble: Slow engine crank Dim lights Corrosion around the battery terminals 3. Inspect All Lights Back-to-school season means shorter days are ahead. Make sure your headlights (high and low beams), brake lights, turn signals, and hazard lights are all working properly so you can see and be seen—especially in the early morning or late evening hours. 4. A/C & Heat Check Late summer can still bring high temps, and fall mornings in Missouri can get chilly. Make sure your air conditioning and heating systems are functioning properly to keep everyone comfortable on the way to school. 5. Review Your Brakes Stop-and-go school zone traffic is tough on your brakes. Listen for: Squeaking, grinding, or vibrations Longer stopping distances A soft or spongy brake pedal If you notice any of these signs, come see us at All-Star Automotive for a brake inspection. 6. Schedule an Oil Change & Maintenance Check If you’re due for an oil change, it’s a great time to knock it out before school starts.
