How often should a car be started if left unused for a long time?

It is recommended to start the vehicle at least every fifteen days, letting it run for over half an hour, and preferably moving the car or driving a short distance. Additional details are as follows: 1. Battery issues: The most common problem when a vehicle is left unused for a long time is the battery. After parking and locking the vehicle, although most electrical components enter a dormant state, certain parts of the vehicle still require power, such as the anti-theft system. Therefore, a small dormant current is generated, which, over time, can lead to a low battery charge, making it difficult to start the engine. To prevent this, it is necessary to periodically start the engine to recharge the battery. 2. Tire issues: Prolonged parking can cause the tires to bear weight at the same spot continuously, potentially leading to deformation over time. This can result in vibrations when driving. Hence, it is advisable to move the vehicle periodically to distribute the weight more evenly across the tires.

Every time my car sits idle for a long time, I worry it might develop issues, so I make sure to start it every weekend. The battery ages quickly, and if left untouched for three weeks, it might not start. I usually let it idle in place for about 15 minutes or take it out for a short drive to warm up the engine, improve oil fluidity, and fully charge the battery. Checking tire pressure is crucial, as prolonged parking can cause the tires to flatten, leading to troublesome tire changes. During rainy seasons, extra attention is needed to prevent rust due to humidity. Maintaining this habit for less than three years, my car has required no major repairs, giving me peace of mind. Don’t forget to clean the air conditioning filter to avoid odor buildup, especially as summer approaches. In short, a little effort can save a lot of money.

Experience has taught me that cars need regular maintenance when left unused for long periods. I recommend starting the car every ten days or so, preferably taking it for a 30-minute high-speed drive. The battery discharges quickly, and insufficient charging can cause damage; engine fluids can solidify and lead to rust, something I learned the hard way—once neglecting it cost me a hefty repair bill. Park on level ground to avoid tilting the body and affecting the suspension. In winter, shorten the interval to once a week because cold weather thickens the oil, making it harder to start. Also, check if the brake lights and safety systems are functioning properly. These small habits, once formed, will keep the car performing like new overall.

What are the new vehicle inspection regulations within 10 years?

New regulations for vehicle inspections within ten years have adjusted the inspection cycle and exemption scope. The relevant details of the new vehicle inspection regulations are as follows: 1. Exemption scope: The exemption scope for motor vehicles has been expanded from the original non-operational small and micro passenger vehicles with 6 seats or fewer to those with 7-9 seats. In other words, after November 20th, non-operational small and micro passenger vehicles with 7-9 seats that are less than 6 years old will be eligible for the exemption policy. 2. Inspection cycle: Exempt vehicles can skip inspections for the first 6 years. From the 6th to the 10th year, inspections are required every 2 years, meaning motor vehicles aged 6-10 years will change from an annual inspection to a biennial inspection. Under the new regulations, exempt new vehicles will only need to undergo 2 inspections within 10 years, specifically in the 8th and 10th years.

How to Deal with a Broken Car Key in the Ignition?

What to do if the car key breaks: 1. Straight key breakage: There are two scenarios. If the metal part breaks, keep the broken piece and take it to a professional key duplication company along with the original key to have it replicated. If the remote part breaks, it cannot be repaired and must be replaced with a new remote key. 2. Folding remote key breakage: This type usually breaks at the mechanical key interface. After breaking, only the shell can be replaced. Save the broken part because it contains a chip, which is useful for later key configuration. 3. Car smart key: This type of key generally does not break, but be cautious of the smart remote part detaching from the mechanical key. The most common issue is the smart remote part falling off, which can prevent the car from starting. Always carry a spare key.

What to Do If a BMW Run-Flat Tire Gets a Nail Puncture?

Here are the relevant solutions for a BMW run-flat tire with a nail puncture: 1. Tire not leaking: When you find that the car tire has been punctured by a nail but there is no air leakage, you can drive slowly to the repair location. In this case, do not pull out the nail, as removing it may cause severe air leakage, making the car undrivable. 2. Tire leaking: If the tire is leaking severely, do not continue driving. Call for a tow truck. If you recklessly continue driving, the tire may be completely ruined, and there are also safety hazards. If the air leakage is slow, you can cautiously drive at low speed to the repair station.

What Causes White Frost on Battery Terminals?

White frost on battery terminals is caused by sulfuric acid solution splashing onto the battery, which corrodes the terminals, cable clamps, and mounting brackets. The reasons for the formation of these oxides are: 1. Poor quality of some batteries: Frequent jolts can cause internal acid to leak during battery use, and this acid corrodes the terminals, producing oxides. 2. Excessive charging current: This leads to significant evaporation of the internal acid, which then reacts with the terminals to produce oxides. 3. Prolonged battery use: Over time, the internal acid evaporates and slowly reacts with the battery terminals, resulting in oxides.

How to Check Engine Oil Level?

Park the vehicle on a level surface under cold conditions, insert the dipstick and remove it—no need to check, just wipe it clean. Insert the dipstick a second time; if the oil level is between the upper and lower marks on the dipstick, it indicates sufficient oil. If the dipstick shows the oil level below the lower mark, promptly add engine oil of the same specification. Below is relevant information about engine oil: 1. Functions of Engine Oil: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and dampen vibrations. Often referred to as the "blood" of a car, it consists of base oil and additives. 2. Oil Level: The oil level should be between the marked lines on the dipstick. If the oil level is too high, it may cause oil to escape through the engine breather and result in blue smoke from the exhaust pipe. Insufficient oil can lead to engine cylinder scoring, damage to the crankshaft and bearings in mild cases, or complete engine failure in severe cases.

How to Interpret Traffic Lights at a Three-Way Intersection?

At a three-way intersection, follow traffic rules accordingly. For international arrow lights, proceed as indicated by the arrows. If it's a circular light, you may proceed straight or turn left only when the light turns green. In cases where multiple lanes share a single light, follow the ground arrows for guidance. When multiple indicator lights are present, adhere to the instructions corresponding to each lane. Below is relevant information about traffic signals: 1. Composition of Traffic Lights: Traffic signals are lights that direct traffic flow, typically consisting of red, green, and yellow lights. A red light means stop, green means go, and yellow serves as a warning. 2. Classification of Traffic Signals: Traffic signals are categorized into: vehicle traffic lights, non-motorized vehicle traffic lights, pedestrian crossing signals, directional indicator lights (arrow signals), lane signals, flashing warning signals, and railway crossing signals at level intersections.
