Preparing your car’s engine for seasonal storage is an critical precaution to ensure it ignites reliably and runs without issues when you bring it out again. Whether you’re storing a classic car, a recreational vehicle like a jet ski, اتوسرویس داوود or even a recreational machine, taking the right precautions can avoid expensive repairs and save you time and effort later.

Fill the tank to the brim—this limits oxygen exposure, which in turn curbs humidity accumulation. Moisture can lead to rust and fuel degradation. Mix stabilizer into the tank before adding fresh fuel. Adhere strictly to the stabilizer’s guidelines. Let the engine idle for 10–15 minutes post-treatment to distribute it evenly across all components. This ensures the fuel delivery system and carburetor or fuel injectors are protected.

Change the engine oil and filter before storage. Residual oil holds harmful byproducts that can corrode internal engine parts over time. Fresh oil provides better protection during months of non-use. When applicable, make sure it’s firmly fastened and inspect for drips post-service.

Disconnect the battery or use a battery tender. Even when the car is off, parasitic drains can drain the battery over weeks or months. Taking it out eliminates risk and shields it from sub-zero temperatures. In cases where removal isn’t practical, use a smart charger to keep it fully powered without overcharging.

Remove the spark plugs and add a small amount of engine oil—about a teaspoon—into each cylinder. Then, turn the crankshaft manually several revolutions to ensure even oil distribution. Reinstall the spark plugs. This step prevents rust from forming on the cylinder walls and piston rings which can cause permanent damage if left untreated.

Seal off intake and exhaust with tape and foam. This keeps out humidity, debris, and pests. Rodents are attracted to warm engines and may nest in the intake or exhaust, causing serious damage when you try to start the car again.

If possible, store the vehicle in a dry, climate-controlled environment. Never store in unheated sheds. Use a ventilated vehicle cover to protect the exterior while allowing air to circulate.

Refer to the manufacturer’s storage guidelines. Older or high-performance engines demand extra care. Implementing all these precautions gives your engine the best chance to remain in top condition until you’re ready to drive again. When you bring the car out, conduct a full pre-start inspection before starting it, and consider changing the oil again after a short run to remove lingering condensation and debris.
