Vehicle Maintenance Checklist – Know When to do What
For preventative maintenance, make it a habit to periodically inspect your vehicle according to the owner’s manual. It’s important to keep your vehicle running efficiently so that you can avoid any potential safety issues. You can also avoid costly vehicle repair needs if you catch something early rather than let it go unnoticed.

Generally, your vehicle maintenance checklist should consist of the following:
Once a Month:
Oil Level – Check the oil level on the dipstick with the engine off to see if the oil level is low. If it is low, you will need to refill the oil tank. If you’re not sure how to do this, you can consult a professional who will help you select the proper type of oil for your vehicle.
Washer Fluid Level – Under the hood of your vehicle is a plastic container that contains the fluid for your windshield wipers. If it isn’t full of liquid, you can fill it with a windshield washer solution. During the winter months, you will probably be using more of your washer fluid so be sure to check the level on a regular basis.
Tire Pressure/Wear – Check tire condition and pressure. Do they look low or are there any visible cracks? You need tires that are in good condition so that you can brake and steer properly.
Once Every 3 Months:
Automatic Transmission Fluid – If your vehicle hesitates when your automatic transmission shifts gears, get the transmission fluid level checked. Replacing your transmission fluid according to your vehicle manufacturer’s recommendations helps preserve the life of the transmission and helps maintain your vehicle’s warranty.
Brake Fluid – Keep the brake fluid in the master cylinder at the proper level. It’s important to be proactive, but if you think your vehicle leaking brake fluid, don’t drive it, tow it!
Every Six Months:
Windshield Wiper Blades – If your wipers have been making a mess of your windshield, it’s time to replace your windshield wiper blades. The metal blades are a little more expensive than the rubber wiper inserts, but if your old ones look corroded or generally aren’t in good shape, they should be replaced.
Power Steering – Eliminate the moaning and groaning caused by your faulty power steering system by checking and getting your power steering fuel changed. If there isn’t enough fluid, steering becomes more difficult and either the pump or rack and pinion could be damaged without fluid to cushion them.
Remember, this is a general checklist that you can follow to keep up with your vehicle maintenance. If you notice an issue, or feel something isn’t right, don’t hesitate to get your vehicle checked out. It’s never fun to deal with vehicle issues, but it’s part of owning a vehicle. It’s your responsibility to make sure your vehicle is safe to drive at all times.
Frequently asked questions
What should I check on my vehicle every month?
Run through three quick checks once a month: oil level, washer fluid level, and tire pressure and wear. For oil, pull the dipstick with the engine off and confirm the level is in range, top off with the correct oil type if it's low. Open the hood and refill the windshield washer fluid reservoir as needed (especially in winter when you'll burn through it fast). Inspect each tire for low pressure and visible cracks or wear, because tires in poor condition compromise braking and steering.
What maintenance items should I check every three months?
Every three months, check your automatic transmission fluid and brake fluid. If your vehicle hesitates when shifting gears, get the transmission fluid level looked at and follow your manufacturer's replacement schedule to protect the transmission and keep your warranty intact. Keep the brake fluid in the master cylinder at the proper level. If you suspect a brake fluid leak, do not drive the vehicle, have it towed to a shop. Brake fluid leaks are a top-tier safety issue.
When should I replace my windshield wipers and check power steering?
Plan to inspect both every six months. If your wipers are leaving streaks, making noise, or smearing the windshield, the blades are due for replacement. Metal-frame blades cost a bit more than rubber inserts but last longer and clear better. For power steering, check the fluid level periodically and replace the fluid per your manufacturer's schedule. Steering that's groaning or feels heavy is often a low-fluid symptom, and running the pump dry can damage the pump or the rack and pinion.
Why does preventative vehicle maintenance matter?
Two reasons: safety and cost. A vehicle that's regularly inspected catches small problems before they become safety hazards on the road. It's also significantly cheaper to top off fluid or replace a worn part on schedule than to repair the larger system that fails when you ignore it. Use your owner's manual as the source of truth for intervals and fluid types, and don't hesitate to bring the car to a professional if you notice something off. Owning a vehicle means taking responsibility for keeping it safe to drive.
What if I notice something wrong between scheduled checks?
Don't wait for the next interval on your maintenance calendar. If something feels, sounds, or smells off, whether it's a new noise, a dashboard warning light, a soft brake pedal, or vibration in the steering wheel, get it checked promptly. Catching an issue early is almost always cheaper than letting it cascade into a bigger repair, and far safer than discovering the problem on the highway. The checklist is a baseline; your own attention is the upgrade.
