Quick reference
| Mileage | Service | Notes |
|---|---|---|
| 5,000 mi | Tire rotation; brake/fluids/undercarriage inspection; lube propeller shaft (if equipped) | Toyota schedules inspections and tire rotation every 5,000 miles. Severe duty: consider 5,000‑mile oil changes. |
| 10,000 mi | Engine oil & filter; repeat 5,000‑mile checks | 0W‑20 synthetic. Toyota normal service oil change is every 10,000 miles/12 months on the 5.7L V8. |
| 15,000 mi | Cabin and engine air filter inspect; repeat 5,000‑mile checks | Replace early if driving dusty or off‑road. |
| 20,000 mi | Repeat 5,000‑mile checks | — |
| 25,000 mi | Repeat 5,000‑mile checks | — |
| 30,000 mi | Replace engine air filter and cabin air filter; inspect brake pads/rotors/drums; inspect drive belt | Toyota commonly calls for filter replacement about every 30,000 miles under normal conditions. |
| 35,000 mi | Repeat 5,000‑mile checks | — |
| 40,000 mi | Repeat 5,000‑mile checks | — |
| 45,000 mi | Repeat 5,000‑mile checks; brake fluid test/flush as needed | Toyota US does not specify a fixed brake fluid interval; a 2–3 year (30k–45k) flush is a common preventive practice—verify with the owner’s manual and fluid test. |
| 50,000 mi | Repeat 5,000‑mile checks | — |
| 55,000 mi | Repeat 5,000‑mile checks | — |
| 60,000 mi | Inspect/replace accessory (serpentine) belt as needed; transmission, transfer case, and differential fluids inspect (change sooner if severe duty) | No routine trans/diff/transfer case fluid changes under normal service per Toyota; towing/off‑road may justify 60k–90k service. |
| 65,000 mi | Repeat 5,000‑mile checks | — |
| 70,000 mi | Repeat 5,000‑mile checks | — |
| 75,000 mi | Repeat 5,000‑mile checks | — |
| 80,000 mi | Repeat 5,000‑mile checks | — |
| 85,000 mi | Repeat 5,000‑mile checks | — |
| 90,000 mi | Repeat 5,000‑mile checks; brake fluid test/flush as needed; inspect accessory belt | Replace belt if cracking/noise. |
| 95,000 mi | Repeat 5,000‑mile checks | — |
| 100,000 mi | Replace engine coolant (Toyota SLLC) | Factory interval: first coolant service at 100,000 miles/10 years, then every 50,000 miles/5 years thereafter. |
| 105,000 mi | Repeat 5,000‑mile checks | — |
| 110,000 mi | Repeat 5,000‑mile checks | — |
| 115,000 mi | Repeat 5,000‑mile checks | — |
| 120,000 mi | Replace spark plugs (iridium); inspect PCV valve; timing chain inspection (noise/leaks only) | 5.7L 3UR‑FE uses iridium plugs (120k interval) and a timing chain (no routine replacement). PCV: not a fixed interval—inspect/replace if sticking. |
| 125,000 mi | Repeat 5,000‑mile checks | — |
| 130,000 mi | Repeat 5,000‑mile checks | — |
| 135,000 mi | Repeat 5,000‑mile checks; brake fluid test/flush as needed | Typical 2–3 year cadence. |
| 140,000 mi | Repeat 5,000‑mile checks | — |
| 145,000 mi | Repeat 5,000‑mile checks | — |
| 150,000 mi | Replace engine coolant (second service after the 100k change); inspect accessory belt and drivetrain fluids | Coolant is every 50k after the first 100k interval. Consider trans/diff/transfer fluid service by this mileage if towing or off‑road use. |
Additional factory items and notes:
- Fuel filter: In‑tank, non‑serviceable under normal conditions; no routine replacement.
- Transmission fluid: Toyota WS, no routine change under normal service; inspect for leaks/condition. Consider 60k–100k drain & fill if severe duty.
- Differential/transfer case: Inspect fluid level/leaks at each service. Severe duty may warrant 15k–30k changes.
Severe‑duty schedule (towing, dusty, short trips, extreme temps)
- Engine oil & filter: Shorten to every 5,000 miles or 6 months when towing, frequent short trips, extended idling, or dusty/off‑road use.
- Air filters: Inspect every 5,000 miles; replace as often as 15,000–20,000 miles in dust.
- Differential and transfer case fluids (4x4): Change every 15,000–30,000 miles with heavy towing/off‑road; otherwise inspect.
- Transmission fluid: Consider 60,000–90,000‑mile drain & fill if towing/hauling frequently. Use Toyota WS only.
- Brake fluid: Moisture test annually; flush about every 2–3 years if the test indicates contamination.
- Coolant: Follow factory—first at 100k/10y, then every 50k/5y. Severe duty typically does not change this interval unless overheating/repairs occur.
- Propeller shaft lubrication: If equipped with serviceable fittings, lube at every 5,000 miles.
Always verify with the 2020 Tundra Owner’s Manual and Warranty & Maintenance Guide for your VIN and drivetrain.
Known issues by mileage (2007–2021 Tundra generation)
- 0–30k: Premature air filter clogging in dusty/off‑road use; steering wheel vibration from uneven tire wear if rotations are skipped (follow 5k rotations).
- 30k–60k: Brake judder or pulsation from heat‑spotted rotors under heavy towing; wheel bearing noise is uncommon but inspect if tire cupping/vibration appears. Early seepage at the water pump can occur—monitor coolant crust at the pump weep hole.
- 60k–100k: Accessory (serpentine) belt glazing/cracking, idler noise; rear differential seep at cover/gasket; driveshaft slip‑yoke clunk on take‑off (lubrication helps on serviceable shafts).
- 100k–150k: Coolant service due; valve cover and cam tower oil seepage may begin; oxygen/AFR sensors may age and set efficiency codes. Secondary air injection system failures were more common on earlier years but are still possible—watch for P0418/P2440‑series codes.
These are not guaranteed failures—use them as inspection cues aligned with the mileage services.
Estimated cost per service
- Oil & filter (0W‑20 synthetic): $85–$140

What you can DIY vs shop
DIY‑friendly
- Engine oil & filter (with proper tools and torque specs)
- Engine and cabin air filters
- Tire rotations (if you have a jack/stands and torque wrench)
- Propeller shaft lubrication (if your truck has zerk fittings)
- Accessory belt inspection/replacement (experienced DIYers)
Shop‑recommended
- Brake fluid flush with moisture/boiling‑point testing
- Coolant exchange with proper bleeding and waste handling
- Transmission WS fluid service (no dipstick; temperature‑based fill procedure)
- Differential/transfer case services (correct fluid spec/levels are critical)
- Spark plug replacement (tight quarters, risk of thread damage if done improperly)
- Diagnosis of leaks, driveline noises, and any MIL/engine codes
If any interval here lists a typical range, that reflects common industry practice when Toyota does not set a fixed U.S. interval. When in doubt, default to the 2020 Tundra Owner’s Manual and the Toyota Warranty & Maintenance Guide for your exact configuration.
