Maintenance Schedule


Vehicles need regular maintenance if you want them to run their best for the long haul. We’ve all seen those vehicles on the road that were manufactured 15 or 20 years ago, and you can make a safe bet that the owner of the vehicle has kept up with regular maintenance. But if you’re wondering how you can get the most mileage out of your vehicle, then you should know that there are a few key times that you should have it looked at. You should always consult your user manual, as vehicles can vary depending on the make, model, and year, but as a general guideline, there are some things that you should have inspected at 15,000 miles, 30,000 miles, 60,000 miles, and 90,000 miles.


When your vehicle is fairly new, any maintenance should be minimal. You should be having your oil changed every 5,000 to 10,000 miles if you have a newer vehicle. Again, look at your user manual to know how your vehicle was designed. Also, you should have your air filter checked so that you know that you’re breathing the cleanest air. You see, the air filter is responsible for filtering the air in the cabin, so if it’s dirty, you could be breathing more dust, mildew, and allergens.

  • Oil Change – Drained and Replaced
  • Check All Fluid Levels – Top Up as Needed
  • Tires Rotated and Balanced
  • Check Air Filter – Replace as Needed


Thankfully, if you’re vehicle’s odometer is reading this mileage, it’s unlikely that you’ll need very much done. Continue to have your mechanic check what they did at the 15,000-mile mark, but also have your fuel filter checked and replaced, if necessary.

This is the point that your mechanic might be telling you that you need to replace a few things. Of course, have your mechanic check the same things that they did when your vehicle only had 30,000 miles on it, but you should also have your spark plugs looked at. If they’re made of copper, it might be time to replace them. If they’re made of iridium or titanium, you probably have more time before they need replacement because these materials tend to last longer. You should also have your transmission fluid and coolant replaced. The transmission fluid lubricates the moving parts inside the transmission, so having clean transmission fluid can extend the life of your transmission. And coolant ensures that your radiator doesn’t overheat. This is also the time that you should have your brake fluid checked, brake pads checked and probably replaced, and you should make sure that your rotors are in good shape, as they can wear out if your brake pads have worn thin.

If you didn’t need to have your spark plugs replaced before, you might need to have them replaced at this point. In addition, make sure that you have all of your valves, hoses, and belts checked. These are made of rubber, and after repeated use, they can wear thin or crack. It’s very important to have your timing belt checked because if it connected to expensive parts on your vehicle, and if the belt breaks when your car is running, the belt could do a lot of damage that won’t be cheap to fix. Finally, your power steering fluid needs to be checked. You’ll know that it’s getting low or old if you hear sounds as you turn the wheel or if the wheel is difficult to turn.
