What does a 40 000 mile service include?
A typical 40,000-mile service includes an oil change and filter replacement, tire rotation, cabin and engine air filter checks, brake inspection, and fluid level checks, with additional items depending on your vehicle and manufacturer schedule.
Core maintenance you can expect
These tasks form the backbone of most 40k services and are commonly performed across a wide range of vehicles.
- Oil and oil filter change
- Engine air filter check and replacement if needed
- Cabin air filter check and replacement if needed
- Tire rotation and tire pressure check
- Brake system inspection (pads, rotors, calipers, lines)
- Fluid level checks and top-offs (coolant, brake fluid, transmission fluid, power steering fluid, windshield washer)
- Belts and hoses inspection for wear or leaks
- Suspension and steering components inspection
- Battery health check and electrical system diagnostic
Across most models, these core items are designed to keep the engine running smoothly, prevent unexpected breakdowns, and ensure safe operation as the odometer climbs.
Vehicle-specific items you might see
Not every car requires every item at 40,000 miles. Some vehicles have longer intervals for certain components, while others may need additional tasks based on engine design, climate, or driving conditions.
- Spark plug inspection or replacement (often scheduled around 60,000–100,000 miles, but some engines use early replacement if wear is detected)
- Timing belt replacement or timing chain inspection (belted engines may require replacement around 60,000–100,000 miles; chains are inspected for wear)
- Transmission service (fluid level check, leak inspection, possible fluid replacement or flush, depending on manufacturer)
- Differential or transfer case fluid inspection/replacement (for 4WD/AWD vehicles)
- Coolant/antifreeze replacement as per manufacturer schedule
- Diesel particulate filter (DPF) checks for diesel engines, with cleaning or regeneration steps if needed
- Fuel system maintenance (fuel filter checks or replacements where applicable)
- Brake fluid flush or replacement (often on multi-year intervals or based on humidity and usage)
- Alignment check and tire balance if wheels were rotated or replaced
- Wiper blade replacement if worn
Always verify which items apply to your exact make and model by consulting the owner's manual or speaking with your service adviser.
How to approach a 40,000-mile service
Before you authorize any work, ask your service provider to walk you through the recommended items for your vehicle, explain which items are standard at 40k versus optional, and provide a transparent estimate. Different brands and dealerships may package the service differently, and some items may be covered under a warranty or service plan.
Additionally, keep your service records organized and aligned with your vehicle’s maintenance schedule. Regular documentation helps preserve resale value and ensures you’re meeting manufacturer recommendations.
Summary
A 40,000-mile service is a mid-life maintenance check focused on refreshing essential fluids, replacing consumables like oil, filters, and tires, and inspecting major systems such as brakes, belts, and suspensions. While core items are common across many vehicles, several tasks depend on the exact make, model, and driving conditions. Always refer to the owner’s manual and confirm with your technician which items apply to your car.
Is 40,000 miles considered high mileage?
If you see a used car that's just two years old and has 40,000 or 50,000 on the odometer already, that's a bit of a red flag, as it shows that the car has been driven far more than other examples in the same year, make and model. That said, the 12,000 figure, while a good rule of thumb, isn't infallible.

What is the 30 60 90 rule for car maintenance?
The 30-60-90 maintenance schedule refers to key services most vehicles need as they hit those mileage milestones. At 30k miles, you're usually handling light wear; by 60k, deeper parts need attention; at 90k, it's time to refresh major systems before serious wear sets in.
How long does a 40k service take?
The time required depends on your vehicle's needs, but most 40,000-mile services take a few hours.
