What Is 30/60/90K Vehicle Maintenance?

Routine maintenance is the key to keeping your vehicle reliable, safe, and running efficiently. Ignoring scheduled service might not cause immediate issues, but over time, neglect leads to costly breakdowns and unexpected repairs.

One of the best ways to stay ahead of vehicle problems is to follow the 30/60/90K maintenance schedule. In this post, we’ll break down what those numbers mean, what you should expect at each milestone, and how these intervals help extend the life of your car.

What Does 30/60/90K Mean?

The 30K, 60K, and 90K markers refer to the mileage intervals at which your vehicle should undergo factory-recommended maintenance. These are comprehensive service check-ins designed to catch wear and tear before it leads to mechanical failure.

Every car manufacturer offers specific guidance for these intervals, but as a general rule of thumb, major service should be performed every 30,000 miles or about once every three years.

What Services Are Included at Each Interval?

Each milestone includes both preventive maintenance and a series of inspections. Here’s a breakdown of what you can typically expect:

30,000-Mile Service

• Oil and oil filter change
• Brake inspection
• Tire rotation and tread check
• Inspection of belts and hoses
• Air filter and PCV valve check
• Wiper blades and exterior lights check

60,000-Mile Service

Includes everything from the 30K interval, plus:

• Coolant system inspection
• Drive belt and timing belt inspection
• Suspension system check
• Steering and linkage inspection
• Transmission fluid and filter service (depending on make)

90,000-Mile Service

Everything from the 30K and 60K services, plus:

• Spark plug replacement
• Fuel system inspection and cleaning
• Timing belt replacement (if required by manufacturer)
• Additional part replacements based on wear or manufacturer recommendations
