Yes, you can usually drive a car that's been in storage, but it is not as simple as just turning the key. The vehicle requires a thorough inspection and specific preparatory steps before it's safe for the road. Jumping straight in and driving a car that has been sitting for months or years can lead to immediate mechanical failure or cause expensive long-term damage.
The primary concern is fluids and rubber components. Engine oil degrades over time, even when not in use, losing its protective properties. The gasoline in the tank will have likely turned to varnish, clogging the fuel system. Tires develop flat spots and can have internal damage, while belts and hoses can dry-rot and crack.
Before attempting to start the engine, a methodical pre-drive check is essential. Here’s a breakdown of the critical systems to inspect:
| Inspection Area | Key Checks & Potential Issues | Recommended Action |
|---|
| Engine Oil & Fluids | Oil breakdown, low coolant, old brake fluid. | Check levels and condition. Change oil and filter before starting if storage was long-term. |
| Fuel System | Gasoline has turned to varnish, clogging the fuel pump, filter, and injectors. | If possible, drain old fuel. Add fresh fuel and a fuel system cleaner. For long storage, professional cleaning may be needed. |
| Battery | Battery is completely dead and may not hold a charge. | Check voltage. Recharge or replace the battery. Corroded terminals should be cleaned. |
| Tires & Brakes | Tires have flat spots, dry rot, or low pressure. Brake rotors are rusted, brake fluid is contaminated. | Inflate tires to proper PSI and inspect for cracks. Check for severe rust on rotors; the first few stops may be gritty until rust is worn off. |
| Rubber Components | Serpentine belts and coolant hoses may be brittle and cracked. | Visually inspect all belts and hoses for signs of dry rot and replace if necessary. |
After these checks, if the car starts, let it idle until it reaches normal operating temperature. Listen for any unusual noises. Then, test the brakes at low speed in a safe area before heading onto public roads. The first drive should be gentle to allow all components to re-acclimate. For cars stored for over a year, having a mobile mechanic perform this initial inspection is a wise investment for peace of mind.
