30/60/90 Maintenance Explained: What’s Actually Necessary?
What Is 30/60/90 Maintenance?
30/60/90 maintenance refers to the manufacturer’s recommended service milestones every 30,000 miles. These intervals are designed to keep your vehicle running safely, extend its lifespan, and prevent costly breakdowns. At each milestone, mechanics inspect and replace critical components like fluids, filters, belts, and spark plugs. Service needs can vary based on your driving habits and vehicle make.
What Work Is Typically Done at Each Maintenance Milestone?
At 30,000 Miles:
- Replace engine air filter
- Replace cabin air filter
- Tire rotation
- Inspect brake pads and rotors
- Inspect suspension and steering components
- Test battery + charging system
- Top off all fluids
At 60,000 Miles:
- Replace spark plugs
- Replace brake fluid
- Replace transmission fluid (if applicable)
- Replace serpentine belt (if worn)
- Inspect cooling system and radiator hoses
- Check exhaust system and fuel lines
At 90,000 Miles:
- Replace coolant
- Replace timing belt (if applicable)
- Replace fuel filter
- Inspect wheel bearings and driveline
- Comprehensive multi-point inspection
⚠️ Always check your owner's manual—maintenance schedules vary between manufacturers.
Why This Maintenance Actually Matters
Let’s face it—nobody likes spending money on a car that seems to be running fine. But here’s the truth:
- Neglected fluids = costly component failure
- Old spark plugs = poor gas mileage & hard starts
- Worn belts or hoses = sudden breakdowns
By following these intervals, you’re avoiding the “sudden $1,000 repair” scenario and keeping your warranty valid if your car is still under coverage.
