🛠 Every Month (or Before Long Trips)

• Check engine oil level & top up if needed
• Check coolant/antifreeze level
• Check brake fluid level
• Check windshield washer fluid
• Check tire pressures & tread depth
• Quick walkaround: lights, wipers, leaks, warning lights

🛠 Every 5,000–7,500 miles (6 months)

• Oil & filter change (synthetic usually lasts closer to 7.5k, conventional closer to 5k)
• Rotate tires, inspect for wear & uneven tread
• Inspect brakes (pads, rotors, lines, fluid condition)
• Inspect suspension & steering components (ball joints, tie rods, bushings)
• Check belts & hoses for cracks or wear
• Inspect exhaust system

🛠 Every 15,000 miles (12 months)

• Replace cabin air filter
• Inspect engine air filter (replace if dirty)
• Inspect fuel system (lines, injectors, leaks)
• Check alignment & balance if tire wear is uneven
• Inspect battery & clean terminals

🛠 Every 30,000 miles (2–3 years)

• Replace engine air filter
• Replace cabin air filter (if not done earlier)
• Replace brake fluid (most manufacturers recommend every 2–3 years regardless of miles)
• Inspect transmission fluid (replace if dirty or per manufacturer’s schedule)
• Inspect coolant condition (replace if required)
• Inspect spark plugs (replace on copper plugs, inspect on platinum/iridium)
• Inspect wheel bearings & CV joints

🛠 Every 60,000 miles (4–5 years)

• Replace spark plugs (iridium/platinum usually last to ~100k, but check condition)
• Replace transmission fluid & filter (unless sealed “lifetime” unit—still worth checking)
• Replace engine coolant
• Replace serpentine/accessory belt
• Inspect timing belt (if applicable) – many are due around 60–100k

🛠 Every 90,000–100,000 miles (6–8 years)

• Replace timing belt (if equipped) & tensioner, water pump at same time
• Replace spark plugs (if iridium/platinum)
• Inspect/replace ignition coils as needed
• Replace differential/transfer case fluid (for AWD/4x4 vehicles)
• Inspect fuel filter (replace if not “lifetime”)
• Replace PCV valve

🛠 Every 120,000 miles (10 years)

• Replace coolant again
• Replace transmission fluid (if not already serviced)
• Replace major rubber components (hoses, bushings) as needed
• Inspect catalytic converter & emissions system

🛠 As Needed

• Tires: replace every 40–60k miles depending on wear
• Brake pads: usually 30–70k depending on driving style
• Rotors: replace or resurface with pad changes if worn
• Battery: 3–5 years typical lifespan
• Wipers: 6–12 months
