Whether you’re going on holiday, working remotely, or simply using public transport more often, you might find yourself leaving your car unused for an extended period. But how long can you safely leave your car unattended without risking damage? While most cars can handle being parked up for a few weeks, there are several factors to consider, such as battery health, tyres, and environmental conditions.
In this blog, we’ll explore how long you can safely leave your car and what steps you can take to protect it, including the option of professional car storage.
Battery Health: The First Concern
One of the most common issues with leaving a car for too long is a drained battery. Modern cars are loaded with electronics, from alarms to infotainment systems, which continue to draw a small amount of power even when the car is off. If your car is left for a week or two, especially in colder weather, there’s a good chance the battery may lose its charge.
Generally, a car battery can last for up to two weeks without being driven. Beyond that, you’ll likely start to see problems. For those who plan on leaving their vehicle unused for longer than this, a few precautions can help. Consider disconnecting the battery or using a trickle charger to maintain its charge. Alternatively, if your car will be unused for months, a professional car storage facility can help keep the battery in optimal condition, with staff regularly checking the vehicle’s electrical health.
Tyres: Avoiding Flat Spots
Another concern with leaving your car stationary for an extended period is the tyres. Over time, tyres can develop flat spots, especially if the car isn’t moved for several weeks. This happens because the weight of the car presses down on the same part of the tyre, causing it to lose its shape.
In most cases, flat spots will disappear after driving for a few miles. However, if the car has been left stationary for several months, these flat spots can become permanent, meaning you’ll have to replace the tyres. To prevent this, try to move the car slightly every few weeks. Alternatively, in professional car storage, vehicles are regularly moved to prevent tyre damage and maintain their condition.
Fuel: Does It Deteriorate?
Fuel doesn’t have an infinite shelf life. If left unused, petrol can start to degrade within three to six months, while diesel tends to last a little longer. As fuel deteriorates, it can lead to issues such as clogged fuel injectors and poor engine performance.
If you’re planning on leaving your car unused for several months, it’s best to keep the tank topped up to prevent moisture from building up inside. Adding a fuel stabiliser can also help maintain the quality of the fuel. In a professional car storage facility, such precautions are standard practice to ensure your car remains in top condition, even during long periods of inactivity.
Paintwork and Exterior Damage
Leaving a car parked outside for an extended period exposes it to the elements. Sun, rain, bird droppings, and tree sap can all damage your car’s paintwork over time. In the UK, the weather can be unpredictable, and even a week of exposure could result in damage to your vehicle’s exterior.
If you’re unable to park your car in a garage, using a quality car cover can help shield it from these external factors. For longer periods, professional car storage provides the ultimate protection. Many facilities offer climate-controlled environments to protect your car from the weather and other potential hazards, ensuring it looks as good as the day you left it.
Interior: Preventing Mould and Bad Odours
A car left unattended for weeks can develop unpleasant smells, especially if there’s any moisture inside. Mould can form in damp areas like the carpets or seats, particularly if the vehicle is parked outside in a humid environment.
Before leaving your car for an extended period, it’s a good idea to clean the interior thoroughly, removing any rubbish, and ensuring the carpets and seats are dry. Leaving the windows slightly open can help with ventilation, but this could also invite unwanted guests like pests. If you’re storing your car for an extended time, a professional storage facility will ensure the interior remains dry and free from unwanted odours or infestations.
Mechanical Health: Rust and Seized Components
If a car is left unused for an extended period, mechanical parts can seize up, and rust can start to form. This is particularly true in the UK, where rain and moisture are prevalent. Components like brake discs are especially susceptible to rusting if the car isn’t driven for a while.
To prevent this, regular movement is essential. Even just rolling the car forwards and backwards a few feet can help keep things in working order. In professional car storage, vehicles are regularly maintained, including starting the engine and moving the car, ensuring that rust and seized components don’t become an issue.
How Professional Car Storage Can Help
If you plan on leaving your car for more than a couple of weeks, especially in less-than-ideal conditions, professional car storage can provide peace of mind. Facilities offer a range of services designed to protect your vehicle from the challenges outlined above. From regular battery checks to preventing tyre flat spots, car storage ensures your car is ready to go when you need it.
In addition to protecting the mechanical and exterior aspects of your vehicle, professional storage often includes climate control, further safeguarding against rust and interior mould. These facilities can store your car for weeks, months, or even longer, ensuring that when you’re ready to hit the road again, your car is in perfect condition.
Final Notes
In the UK, most cars can be left unattended for up to two weeks without issue, but beyond that, the risks of battery drainage, tyre damage, and other problems increase. While there are some steps you can take to mitigate these risks, professional car storage provides the ultimate solution. By entrusting your car to experts, you can ensure it stays in pristine condition, no matter how long you’re away. Whether you need storage for a few weeks or several months, investing in proper car care is a small price to pay for peace of mind.
