Keeping Your Car Ticking Over: How Often Should You Start Your Engine?

For car owners who don’t use their vehicles daily, the question of how often to start the engine is a common concern. Leaving a car dormant for extended periods can lead to a cascade of problems, far outweighing the inconvenience of a brief engine run. The simple answer is: more often than you might think.

While the specifics depend on factors like climate and vehicle type, a good rule of thumb is to start your car’s engine for at least ten minutes once a week, especially if it hasn’t been driven. This seemingly small act performs several vital functions:

• Battery Health: A car battery is a consumable item. Even when not in use, it slowly discharges. A short engine run allows the alternator to recharge the battery, preventing a dreaded “dead battery” scenario. This is particularly critical in colder climates where battery performance is significantly reduced.

• Fluid Circulation: Engine oil lubricates moving parts. Sitting idle for too long allows the oil to settle, potentially leading to increased wear and tear upon restarting. A short run ensures proper oil circulation, lubricating all components and preventing damage from friction. This is also true for other fluids, such as coolant, which helps regulate engine temperature.

• Component Functionality: Various car parts, from fuel pumps to electronic sensors, require occasional activation to remain in optimal working order. Prolonged inactivity can cause these components to seize or malfunction, leading to costly repairs down the line. A regular start ensures everything stays lubricated and operational.

• Preventing Seizing: In extreme cases, prolonged inactivity can cause components to seize up entirely, requiring extensive and expensive repairs or even replacement. This is especially true for older vehicles or those stored in less-than-ideal conditions.

Beyond the Weekly Start:

While a ten-minute run weekly provides a good baseline, consider more frequent starts if:

• Your vehicle is older: Older cars often require more frequent attention.
• You live in a harsh climate: Extreme heat or cold can impact battery life and fluid viscosity.
• Your car is equipped with a sensitive electronic system: Modern vehicles rely heavily on electronics, which benefit from regular power cycles.

Important Considerations:

• Safety First: Always operate your vehicle in a safe and well-ventilated area. Never start your car in an enclosed space without proper ventilation.
• Driving is Best: While regular starts are important, nothing replaces a proper drive. Driving your car allows for a more thorough warm-up and operational check of all systems.

In conclusion, prioritizing regular engine starts, even for a short duration, is a proactive step in maintaining your vehicle’s health and longevity. This small investment of time can prevent significantly larger repair bills and ensure your car remains reliable for years to come. So, set a reminder, grab your keys, and give your car the ten-minute checkup it deserves.
