1. Follow the Owner’s Manual Schedule

The most reliable guide to what your car needs and when is your owner’s manual. It will specify when to change oil, fluids, filters, belts, and more, based on mileage or time. Manufacturers base these intervals on the design of the vehicle. toyota.com+1

Don’t skip this — deviating too much can lead to unnecessary wear or broken warranties.

2. Check and Change Engine Oil Regularly

Clean engine oil is the lifeblood of your car’s engine. Over time, oil degrades and loses its lubricating ability.

Check oil levels monthly (or during every gas stop on long drives) when the engine is cool. Bridgestone Tires+1
Change oil based on the manufacturer’s recommendation — often between 5,000 to 10,000 miles for modern synthetic oils. Kbb.com+2sullivantire.com+2

Using good-quality oil and filters helps reduce friction and extend engine life.

3. Monitor & Maintain Tire Health

Tires are the only parts touching the road. Keeping them in good shape affects performance, safety, and fuel efficiency.

Check tire pressure monthly — tires lose 1–2 PSI per month naturally. State Farm+3Kbb.com+3Allstate+3
Inspect tread depth using the “penny method.” If the top of Lincoln’s head is visible, the tread is too shallow. Kbb.com+1
Rotate tires every 5,000–7,500 miles (or as recommended) to ensure even wear. Car and Driver+2Bridgestone Tires+2

4. Pay Attention to Fluid Levels & Quality

Beyond oil, your car depends on various fluids:

Coolant / antifreeze
Brake fluid
Transmission fluid
Power steering fluid
Windshield washer fluid

Check these periodically, especially before long trips. Dirty or low fluids can lead to damage. Car and Driver+2Allstate+2

5. Test & Maintain the Battery

A weak battery is a frequent cause of breakdowns:

Inspect battery terminals for corrosion and ensure connections are tight. Kbb.com+1
Test battery voltage annually; if it’s under ~12.4 V when the car is off, it’s weakening. Car and Driver+2Allstate+2
Consider replacing batteries every 4–5 years before they fail unexpectedly.

6. Replace Air Filters & Cabin Filters

Filters keep your engine breathing clean and your cabin air fresh:

Engine air filter: a clogged filter reduces performance and fuel efficiency. Car and Driver+2toyota.com+2
Cabin air filter: if airflow drops or you smell odors, it’s time to change it.

Replacement intervals vary, but a good check every 12,000–20,000 miles is common.

7. Inspect Belts, Hoses & Timing Components

Belts and hoses are under constant stress from heat and vibration:

Look for cracks, glazing, frays, or looseness in serpentine belts.
Check hoses for leaks, bulges, or soft spots.
For vehicles with timing belts, follow replacement intervals (often 60,000–100,000 miles).

Failure in this area can cause major engine damage.

8. Keep Lights & Wipers in Good Shape

Visibility is critical:

Test headlights, brake lights, turn signals, and interior lights monthly. Bridgestone Tires+2Car and Driver+2
Replace wiper blades at least once a year or as soon as they streak or smear.

Good lighting and visibility reduce risk.

9. Don’t Ignore Weird Noises, Smells, or Warning Lights

Your car will often give you early warning signs:

Strange sounds (squealing, grinding)
Burning smells
Dashboard warning lights

Don’t delay diagnostics — catching issues early is much cheaper than repairing major damage later. Consumer Reports+2Allstate+2

10. Clean & Protect the Exterior & Interior

Aesthetics matter — but so does protection:

Wash regularly to remove road salt, dirt, and debris.
Wax at least twice a year to protect paint.
Clean the interior — vacuum carpets, wipe surfaces, condition leather.
Underbody washes help prevent rust in cold or coastal regions.

A well-maintained car not only looks better but holds value higher.

Conclusion

These 10 tips are the backbone of good car care. Stick to them as habits, and your vehicle will be more reliable, safer, and more valuable in the long run.
