How Often Should You Change Your Oil? A Complete Guide to Vehicle Maintenance

If you’re unsure about your next oil change, you’re not alone. Understanding maintenance schedules is crucial to keeping your vehicle healthy, reliable, and on the road for years to come.

In this guide, we’ll cover everything you need to know about oil changes, including specifics for the Lexus NX300h and synthetic oil schedules. By the end, you’ll know exactly when to book your next service—and why it matters.

Why Oil Changes Are Essential

Changing your oil regularly ensures your engine stays lubricated, reduces wear, and prevents costly repairs. Depending on your vehicle and driving habits, your maintenance schedule may vary. Typical recommendations:
  • Conventional Oil: Every 3,000–5,000 miles or 3–6 months
  • Synthetic Oil: Every 7,500–10,000 miles or 6–12 months
However, real-world factors often mean more frequent service is needed.
Quick Tip: Heavy traffic, short trips, and extreme temperatures all demand more frequent oil changes.
A&D Repair Recommendation:
  • Due to Michigan’s harsh driving conditions, A&D Repair Inc. recommends changing your oil at least every 5,000 miles or 6 months, whichever comes first.
  • Plus, we offer a free vehicle inspection every 6 months to ensure your car stays safe and reliable year-round!

Special Considerations for Lexus NX300h Owners

If you drive a Lexus NX300h, maintenance guidelines slightly differ from general standards. Manufacturer’s suggestion:
  • Synthetic Oil Only: Change every 10,000 miles or 12 months, whichever comes first.
Our local Michigan recommendation:
  • Given the unique driving conditions here, we suggest servicing your NX300h every 5,000–7,500 miles to optimize engine health and longevity.
Pro tip: Always check your owner’s manual or consult with our ASE-certified technicians to personalize your schedule.

Understanding Synthetic Oil Maintenance

Synthetic oil provides better protection and performance, but it still needs timely changes. Benefits of synthetic oil:
  • Superior high-temperature stability
  • Enhanced engine wear protection
  • Improved fuel efficiency
  • Ideal for turbocharged and performance engines
Suggested synthetic oil change intervals:
  • Normal Driving: Every 7,500–10,000 miles
  • Severe Driving Conditions: Every 5,000–7,500 miles
Always adjust based on your actual driving habits rather than ideal scenarios.
Fun Fact: Some high-mileage synthetic oils help reduce leaks and minimize oil consumption in older vehicles.

Risks of Skipping Regular Oil Changes

Delaying or skipping oil changes can cause:
  • Sludge buildup
  • Overheating engines
  • Decreased fuel efficiency
  • Complete engine failure
Keeping up with oil changes is one of the most cost-effective ways to extend the life of your vehicle. Remember: A $50–$100 oil change today can save you thousands in engine repairs down the road.
