Most of us can recognize an F-14 Tomcat when we see one — thanks to its iconic design and a couple of blockbuster movies. But did you know it was one of the most maintenance-intensive fighter jets ever built, requiring up to 60 hours of service for every hour in the air? The F-117 Stealth Fighter? Even more — over 110 hours of maintenance per flight hour.

If you’ve ever felt like your classic car demands more care than it should, those numbers might offer a bit of comfort. In fact, for many of us, the process of maintaining and restoring these machines is part of the fun. Whether you’re a hands-on gearhead or just enjoy the occasional weekend wrench session, here are five essential maintenance tips to help protect your classic car — and keep it on the road for years to come.

Tip #1: Store Your Classic Car the Right Way

Storing your vehicle properly is one of the most overlooked — yet critical — aspects of classic car preservation.

Avoid Light and Humidity

Ultraviolet light fades vintage paint and interiors, especially in pre-2000 vehicles. Aim for a storage space that stays dark most of the time. If that’s not possible, choose low-blue LED lighting (warm tones preferred). Humidity is another silent killer. Excess moisture leads to rust, corrosion, and rubber fatigue. Use a hygrometer to monitor levels. Ideal humidity? Below 50%. If needed, run a dehumidifier or install A/C.

Keep Critters Out

Mice are notorious for chewing through wiring, nesting under plastic engine covers, and turning gloveboxes into homes. Traps, deterrents, or shop cats — choose your weapon. Don’t assume your garage is sealed tight. If a power cord can fit through a gap, so can a mouse.

Tip: Remove any food wrappers or condiment packets from the cabin. You’d be surprised how many pests are drawn in by the tiniest scent.

Use a Proper Car Cover

A high-quality indoor car cover protects against dust, UV rays, and the occasional shop mishap. Look for breathable, soft-fabric options specifically made for indoor storage — not the budget ones from big-box retailers.

Tip #2: Don’t Forget the Fluids (All of Them)

More Than Just an Oil Change

Fresh oil before long-term storage helps prevent internal corrosion — but don’t stop there. Brake fluid absorbs moisture over time and should be flushed periodically. Coolant should be monitored and changed on schedule to maintain proper pH and corrosion resistance.

Transmission and Fuel Considerations

Automatic transmission fluid? Don’t flush it blindly. A full flush can stir up debris in older systems. A drain-and-fill is usually safer.

Use fuel stabilizer if the car will sit more than a month — and always fill the tank to reduce condensation.

Tip #3: Inspect Bearings and Bushings

Suspension and wheel bearing components take a beating overtime especially in older vehicles.

Bearings

Jack up the car, grip the top and bottom of the wheel, and rock it. Any play or movement could mean worn bearings. Catch this early to prevent costly repairs — or worse, a dangerous failure.

Bushings

Use a flashlight and safe lifting methods to inspect rubber bushings. Cracking, splitting, or dry rot means it’s time to replace them. Poor bushings can drastically affect how a classic car handles — especially in emergency maneuvers.

Tip #4: Keep Fasteners Tight

Torque Matters

Over time, bolts and nuts can loosen from vibration or thermal cycling. Use a torque wrench and refer to your vehicle’s service manual for correct specs. Paint-mark bolts after torquing (just like pro race teams) so you can easily spot any that have shifted.

This small step adds safety, reliability, and peace of mind — and most concours judges won’t deduct for it.

Tip #5: Drive Your Classic Car Regularly

We saved the best for last — because driving your car (while following the guidelines of your classic car insurance company) is one of the best things you can do to maintain it.

It circulates fluids, prevents rubber seals from drying out, keeps brakes functioning, and ensures the battery stays charged. Plus, it gives you the opportunity to spot emerging issues before they turn into expensive problems.

And let’s be honest: it’s also the most fun.

If you follow the above tips, you’ll get more for your maintenance buck, letting you enjoy your classic car where and when you want to. For many of us, owning a classic car is the biggest thrill there is, letting you connect with the past while enjoying the present day. Is it as fun as flying an F-14? Well, we don’t want to brag, but… yes!
