Regular vehicle maintenance is the key to avoiding costly repairs, extending your car's life, and staying safe on Norman roads. Whether you're commuting to work, driving to OU, or traveling Oklahoma highways, this comprehensive maintenance checklist will help keep your vehicle in top condition.
Monthly Maintenance Tasks
Engine Oil Level
Check your oil level monthly using the dipstick. Low oil can cause serious engine damage. If you're consistently adding oil between changes, visit Razas Towing and Recovery for a leak inspection.
Norman tip: Oklahoma's temperature swings can affect oil viscosity. Consider synthetic oil for better performance.
Tire Pressure & Tread Depth
Check tire pressure monthly (including the spare). Proper inflation improves gas mileage and tire life. Use the penny test for tread depth - if you can see Lincoln's full head, it's time for new tires.
Recommended PSI: Found on the driver's door jamb, NOT on the tire sidewall.
Fluid Levels
Check coolant, brake fluid, power steering fluid, and windshield washer fluid. Top off as needed. Dark or dirty fluids indicate it's time for service.
Every 3,000-5,000 Miles
Oil Change
The most critical maintenance task. Modern synthetic oils can go 5,000-7,500 miles, but conventional oil needs changing every 3,000-5,000 miles. Your owner's manual has the exact recommendation.
At Razas Towing and Recovery, our oil changes include a multi-point inspection covering brakes, belts, hoses, and fluid levels - catching small problems before they become expensive repairs.
Every 6 Months or 6,000 Miles
- Tire Rotation: Extends tire life by 20-30%. Front tires wear faster than rear tires on most vehicles.
- Cabin Air Filter: Replace to maintain air conditioning efficiency and air quality, especially important for Oklahoma allergies.
- Battery Check: Test battery charge and clean terminals. Oklahoma heat can shorten battery life to 3-4 years.
Annually or 12,000 Miles
Engine Air Filter
Dirty air filters reduce fuel efficiency by up to 10%. Replace annually or when visibly dirty.
Wheel Alignment
Hitting potholes on Norman streets? Get alignment checked to prevent uneven tire wear.
Brake Inspection
Check brake pads, rotors, and fluid. Squealing or grinding means immediate attention needed.
Coolant Flush
Replace coolant every 2 years. Critical in Oklahoma summers to prevent overheating.

- • Difficulty starting or rough idling

Oklahoma-Specific Maintenance Tips
Norman's climate presents unique challenges:
- Summer Heat: Check coolant before May. Oklahoma summers regularly exceed 100°F, putting extra stress on cooling systems.
- Winter Weather: Keep washer fluid full with freeze protection. Ice storms can appear with little warning.
- Pollen Season: Replace cabin air filters in spring. Oklahoma pollen counts are among the nation's highest.
- Hail Protection: Consider covered parking during severe weather season (March-June).
Creating Your Maintenance Schedule
Keep a maintenance log in your glove box or use a smartphone app. Track:
- Date and mileage of each service
- Type of service performed
- Parts replaced
- Shop that performed the work
- Cost of service
This documentation helps you stay on schedule, proves maintenance when selling your vehicle, and can help diagnose recurring problems.
