Long term parking of cars (such as exceeding one month) can easily cause various problems and even irreversible damage. The following are specific impacts and response plans:
Battery system failure
-Question:
-Self discharge of the battery leads to power loss (ordinary lead-acid batteries lose 5-15% of their electricity per month)
-Long term deep discharge causes plate sulfurization, shortening battery life
-Response:
-Start the vehicle and run it for 15 minutes every week or disconnect the negative pole
-Use intelligent charger maintenance (such as CTEK MXS 5.0)
Tire deformation and aging
-Question:
-Long term compression on one side leads to tread deformation (rubber memory effect)
-Risk of accelerated ply failure due to decreased tire pressure
-Response:
-Fill the tire pressure to the standard value+0.3bar (such as standard 2.5bar to 2.8bar)
-Move the vehicle every month to change the tire force point (at least 10cm displacement)
Oil deterioration and precipitation
|Oil type | Deterioration behavior | Risk | Response measures|
|--------------|-----------------------------|---------------------------|-------------------------------|
|Engine oil | Oxidation and acidification, additive failure | Increased engine wear | New engine oil needs to be replaced after being parked for more than 6 months|
|Transmission oil | Layered sedimentation, decreased lubrication performance | Shifting jerks/abnormal gear wear | Replace long-lasting oil before long-term parking|
|Brake oil | Moisture absorption leads to a decrease in boiling point (DOT4 standard moisture content ≤ 3%) | Brake efficiency degradation/air resistance phenomenon | Check the moisture content before parking, replace if it exceeds 3%|
|Fuel | Gel precipitation clogging fuel injector (ethanol gasoline has a shelf life of only 1 month) | Difficulty starting/decreased power | Adding fuel stabilizer (such as STA-BIL)|
Corrosion of mechanical components
1. Inside the engine
-The loss of oil film on the cylinder wall leads to direct metal contact
-Suggestion: Before parking, inject a small amount of oil into the spark plug hole and manually rotate the crankshaft
2. Braking system
-Brake disc rusting and sticking (especially in humid environments)
-Response: Gently press the brake every month to move the vehicle and remove the surface rust layer
3. Metal pipelines
-Internal oxidation and corrosion of brake oil pipes and fuel pipes
-Inspection: When reusing, it is necessary to focus on checking the sealing of the pipeline
Electronic system malfunction
-ECU sleep current abnormality: Some models have a large problem of dark current flow (such as the old Audi A6L, where the dark current should be less than 50mA)
-Moisture in electronic components: humidity above 70% can easily cause mold growth on circuit boards
-Solution:
-Wrap the ECU module in a moisture-proof bag
-Disconnect non essential electrical fuses
Rubber components aging
-Affected area:
-Adhesive hardening of wiper rubber strip
-The sealing strip of the car door/sunroof is cracked
-Brittle transmission shaft dust cover
-Protective measures:
-Use silicone lubricant to maintain rubber parts
-Leave a gap of 3-5mm on the car window to maintain ventilation (with anti rodent measures in place)
External environmental damage
|Damage type | Specific manifestations | Protection plan|
|--------------|-----------------------------|-----------------------------------|
|Oxidation of paint surface | UV light causes powdering of varnish layer | Car cover+regular waxing (ceramic plating is recommended)|
|Animal Invasion | Mouse Bites/Nesting | Camphor Balls/Ultrasonic Rodents Placed in Engine Compartment|
|Dust accumulation | Blockage of air conditioning inlet | Installation of dust filter screen|
|Chassis corrosion | Snow melting agent/rainwater erosion | Spraying chassis armor (such as 3M 08881)|
Long term parking operation standards
1. Preparation before parking:
-Clean the interior and thoroughly dry it
-Fill the fuel tank with 95% volume of fuel (reducing air contact)
-Enable electronic handbrake instead of mechanical handbrake (anti jamming)
2. Maintenance during parking:
-Start the engine every month until the water temperature is normal (it is recommended to cooperate with battery charging)
-Use a jack to support the chassis and reduce suspension/tire load
3. Re enable the process:
-Check the oil level and chassis leakage first
-Keep idling for 10 minutes after the first start before driving
Key maintenance for different parking cycles
-1-3 months: Pay attention to battery and tire pressure
-3-6 months: Need to change oil and check oil circuit
-More than 6 months: It is recommended to conduct a comprehensive overhaul (including replacing rubber parts, cleaning oil circuits, etc.)
Tip: Long term parking can cause more damage to the vehicle than normal use. It is recommended to conduct a system check at least once every two weeks. If long-term storage is necessary, it is recommended to entrust a professional garage for constant temperature and humidity custody.
