Why Perform 30K, 90K, and 120K Services?

If you own a vehicle, somebody has likely told you about service intervals. And while you should be taking your vehicle in for regular service checks to keep it in optimal condition, some intervals require a bit more work than others.

Three of those service intervals are the 30,000, 90,000, and the 120,000-mile service intervals. But what should you expect from these services and why are they so important? We'll go over it all for you here, but don't take them for granted and don't miss these services!

The Importance of Service Intervals

If you own a vehicle, one of the most important things you can do to keep it in good working order is to keep up with the service intervals. Keeping up with the service intervals keeps everything well lubricated so parts don't wear out as quickly, and when it's time to replace parts you can do it right away.

Otherwise, small issues can turn into big problems simply because you didn't fix them right away. Manufacturers set service intervals for a reason, you need to stick with them!

What's in a 30K Service?

Typically, the 30,000-mile service interval consists of routine tasks. These service intervals include an oil and oil filter replacement, air filter replacement, power steering fluid flush, spark plug replacement, cabin air filter replacement, and a full vehicle inspection.

But while these are common services to perform during a 30,000-mile service, it's not a comprehensive list. Each vehicle manufacturer puts out its own service recommendations for each vehicle, and these are the service intervals you should follow.

What's in a 90K Service?

Once your vehicle hits the 90,000-mile service interval, it's likely time for some more routine services. Not only does your vehicle still need the common service intervals like an oil and filter replacement, a tire rotation, a new air filter, a power steering fluid flush, new spark plugs, and a cabin air filter, but it's also time for some more advanced services.

These services include a brake fluid flush, a coolant flush, and a new timing belt. And like every service interval the 90,000 service interval comes with a full vehicle inspection. However, since the vehicle has higher mileage, it's more likely that you'll need to replace other components.

Other components you might need to replace include the brakes and pads, shocks, wheel bearings, and ball joints. What you'll actually need to replace depends on what comes up during the vehicle inspection portion of the service.

But to get a better idea of what to expect check out your vehicle's owner's manual and what they recommend doing during the 90,000-mile service interval.  

What's in a 120K Service?

Another huge service interval you don't want to miss is the 120,000-mile service interval. What exactly goes into this service interval all depends on what services you did or didn't complete at the 90,000-mile interval.

Services you will need to complete include the oil and oil filter, a tire rotation, a new air filter, a power steering fluid flush, spark plugs, a cabin air filter, and a full vehicle inspection. From there you'll want to complete any service the technicians didn't complete at the 90,000-mile service.

Finally, keep in mind that you'll likely need to complete any services you didn't complete the 90,000-mile interval. However, if you already replaced the timing belt, shocks, wheel bearings, and ball joints, you shouldn't need to do it again during the 120,000-mile service.

How Often Should You Take Your Vehicle in for Service?

The answer to this really depends on what type of oil you're using since this is usually the most frequent service you need to complete on your vehicle. If you're using conventional oil you should take your vehicle in roughly every 3,000 miles so the technician can change the oil and inspect the vehicle.

However, if you're using a full synthetic engine oil you only need to bring it in about once every 10,000 miles.

If you want to know the exact service intervals for your vehicle, we recommend looking in your vehicle's owner's manual or by reaching out to a reputable source like Granite Subaru.

Services to Complete Every 10,000 Miles

Oil changes aren't the only service you need to routinely complete on your vehicle and sticking with a 10,000-mile service interval is an easy way to ensure you don't miss any of the basics. In addition to changing the oil and the oil filter, you'll need to rotate the tires, replace the air filter, and replace the cabin air filter every 10,000 miles.

In addition to these routine services, the technician can check if your vehicle needs any other types of routine maintenance and complete a thorough vehicle inspection. Letting a technician get a good look at your vehicle every 10,000 miles ensures they can catch issues while they're still small and prevent them from causing further damage.
