How many miles should you do a full service?

Most cars benefit from a full service every 10,000–12,000 miles or once a year, whichever comes first, though some models stretch to 15,000–20,000 miles under manufacturer “flexible” schedules. The right interval depends on your vehicle, how you drive, and what the automaker’s maintenance system or owner’s manual specifies; many modern cars use oil-life monitors or condition-based service to set the timing.

Typical service intervals by vehicle type

The following guide outlines common full-service intervals across different vehicle categories and regions. Always prioritize the owner’s manual and the car’s maintenance indicator, which are tailored to your specific engine, oil specification, and usage profile.

• Modern gasoline/diesel cars: 10,000–12,000 miles or 12 months is a common benchmark.
• USA/Japan on synthetic oil: typically 10,000 miles/12 months; “severe service” often 5,000–7,500 miles.
• European “flexible/long-life” systems (e.g., BMW, Mercedes-Benz, VW/Audi): up to about 15,000–20,000 miles or as much as 2 years when the service indicator allows and approved long-life oil is used.
• Older/high-mileage vehicles: 6,000–10,000 miles or 6–12 months, as wear and minor leaks can demand closer attention.
• Hybrids: typically similar to comparable gasoline models (often 10,000 miles), with extra checks for cooling systems and regenerative braking components.
• EVs: no engine oil; plan inspections annually or every 12,000–15,000 miles for items like tires, brakes, coolant loops (where fitted), and cabin filters.

These ranges reflect broad industry practices as of 2025; the safest rule is to follow the vehicle’s maintenance minder or schedule and adjust based on your driving conditions.

Factors that change your interval

Your actual service cadence can shift substantially based on how and where you drive, the fluids and parts your vehicle uses, and any warranty or lease stipulations. Consider the factors below when deciding whether to shorten or extend intervals.

• Severe driving: frequent short trips, heavy idling, extreme heat/cold, dusty/gravel roads, towing/hauling—shorten to about 5,000–7,500 miles between full services.
• Oil type and spec: high-quality synthetic oils meeting the automaker’s latest standard support longer intervals; conventional oils generally require shorter ones.
• Oil-life/condition monitors: modern systems calculate service needs from temperature, load, and drive cycles; don’t exceed the system’s time limit (often 12 months) even if mileage is low.
• Vehicle age and wear: older cars may consume oil or develop seepage, making more frequent checks prudent.
• Warranty/lease requirements: some programs mandate fixed intervals or specific services to remain in compliance.
• Fuel/aftertreatment systems: diesels with DPFs, and turbocharged engines that stress oil, may benefit from sticking closely to manufacturer guidance.

If several of these factors apply at once—say, towing in hot weather with lots of stop‑and‑go—err on the conservative side and service sooner.

What’s included in a “full service”?

“Full service” is more comprehensive than a simple oil change, bundling inspections and replacements that safeguard reliability, efficiency, and safety. While specifics vary, reputable full-service checklists will include many of the following items.

• Engine oil and filter replacement (correct spec and capacity).
• Cabin and engine air filter checks/replacement; fuel filter where applicable.
• Brake system inspection: pads, rotors, lines, fluid test; parking brake function.
• Coolant level/condition check; top-up or change per schedule.
• Belts, hoses, and visible seals inspection for wear and leaks.
• Suspension and steering joints, boots, and shocks/struts inspection.
• Tire rotation, tread depth/condition, pressure set; alignment check if needed.
• Battery test and charging/starting system check.
• Software updates/TSBs when applicable.
• Spark plugs at scheduled intervals; ignition components inspection.
• Transmission, transfer case, and differential fluid checks/changes per schedule.
• Exhaust and emissions components (including DPF/AdBlue on diesels) checks.
• Hybrid/EV items: coolant loops for power electronics, cabin filter, brake service, and high-voltage system visual checks per OEM procedures.

The precise content should match your model’s maintenance schedule; ask your shop for the itemized checklist and parts/lubricants used.

Signs you shouldn’t wait

Regardless of mileage, certain symptoms call for immediate attention and may warrant a full service or targeted repair sooner than scheduled.

• Warning lights (check engine, oil pressure, battery/charging, brake/ABS).
• New noises, vibrations, or burning/oily smells.
• Hard starts, rough idle, misfires, or poor acceleration.
• Soft or pulsating brake pedal, longer stopping distances, or squeals/grinds.
• Visible fluid leaks or frequent top-ups.
• Overheating or fluctuating temperature gauge.
• Noticeable drop in fuel economy.

Addressing issues early typically reduces repair costs and prevents roadside breakdowns.

How to choose the right interval for your car

Use these steps to set a practical, warranty-safe full-service cadence tailored to your vehicle and driving.

1. Check your owner’s manual or maintenance guide for the official schedule and oil specification.
2. Observe your vehicle’s oil-life/maintenance minder and never exceed its time limit (commonly 12 months).
3. Adjust for severe use—shorten to 5,000–7,500 miles if you tow, idle, or drive short, cold trips.
4. Use approved synthetic oil and quality filters to support the intended interval.
5. Keep records and receipts; they help with warranty claims and resale value.

Revisiting this plan annually ensures it still matches your current driving and any changes to manufacturer guidance.

Quick reference examples (as of 2025)

These common-brand practices illustrate how varied full-service timing can be; always defer to your specific model’s manual and in-car indicators.

• Toyota/Lexus: many models on synthetic oil at 10,000 miles/12 months; severe use often serviced at 5,000-mile intervals.
• Honda/Acura: Maintenance Minder typically calls for service around 7,500–10,000 miles, depending on driving conditions.
• Ford/Lincoln: Intelligent Oil-Life Monitor sets intervals commonly between 7,500–10,000 miles; heavy-duty/diesel models may differ.
• BMW/Mini: Condition Based Service can allow up to roughly 10,000–15,000 miles or 12–24 months, depending on use and oil spec.
• Mercedes-Benz: ASSYST/ASSYST Plus varies by model, often near 10,000–15,000 miles; time limits may be 1–2 years per regional guidance.
• VW/Audi: North America typically fixed 10,000-mile intervals; EU “LongLife” up to about 18,600 miles (30,000 km) or 2 years with approved oil.
• Tesla: no engine oil; follow inspection items (e.g., tire rotation about every 6,250 miles, cabin filter typically every 2 years, brake fluid tests periodically).

Even within a brand, engines and model years differ; check the exact service schedule keyed to your VIN.

Summary

Plan a full service about every 10,000–12,000 miles or annually, unless your car’s maintenance system or manual specifies otherwise. Shorten the interval for severe driving, older vehicles, or when symptoms appear; some European models can safely extend to roughly 15,000–20,000 miles or up to two years when using approved long-life oils and following the service indicator. When in doubt, the owner’s manual and your car’s oil-life monitor are the final word.
