Under normal temperature and sealed storage conditions in the fuel tank, 92 octane gasoline has a shelf life of about 3 months. The following are specific details about gasoline stored for too long: 1. The effective components of gasoline are its light fractions, which are highly volatile. Gasoline stored for too long will have reduced combustible parts and increased concentration of heavy gum-like substances. 2. Prolonged storage will reduce its anti-knock properties, which can easily lead to engine damage. Do not let the gasoline run completely dry; ensure the fuel tank has as little gasoline as possible. Additional Information: When parking a vehicle for an extended period, try to choose a shaded indoor location to avoid exposure to sunlight, which may cause the car to self-ignite.

What are the symptoms of a bad clutch plate?

Symptoms of a bad clutch plate: 1. The clutch engagement point becomes higher. When starting the vehicle, you need to release the clutch pedal higher than before (e.g., from originally 1 cm to now 2 cm) before the vehicle moves; 2. Noticeable decrease in vehicle power. With no engine abnormalities, the car feels sluggish during starts or climbing hills, and there's insufficient power despite high engine RPMs, indicating clutch slippage; 3. Metallic grinding noises when depressing or releasing the clutch pedal, which likely indicates severely worn clutch plates; 4. Uneven engagement when releasing the clutch during starts, causing jerky forward/backward movements, along with a rough or sticky feel when operating the clutch pedal, requiring clutch plate replacement.

Is the Transmission the Same as the Gearbox?

Transmission is indeed the same as the gearbox, also referred to as the gear case. Inside the transmission, gears of different sizes mesh together to increase or decrease rotational speed or torque, thereby enabling the vehicle to change gears. The meshing of gears resembles the interlocking of human teeth, hence the term "gearbox." Transmissions are categorized into manual and automatic transmissions. Manual transmissions include 5-speed manual and 6-speed manual, while automatic transmissions comprise 6-speed automatic, 7-speed dual-clutch, 8-speed semi-automatic, and CVT (continuously variable transmission). The transmission consists of a gear shifting mechanism and a control mechanism, with some vehicles also featuring a power take-off unit. Transmissions can be further classified into stepped, stepless, and integrated types, serving functions such as enabling reverse driving, interrupting power transmission, and altering gear ratios.

What to do if the tire sidewall is cut?

Solutions for a cut tire sidewall: 1. Check whether the damage has affected the internal cord fabric material. If the sidewall is already damaged, the tire cannot continue to be used and must be replaced; 2. If the damage has not affected the cord fabric material, the tire can still be used, but it is necessary to regularly check whether the damage has expanded or if the cords are damaged. If so, the tire must be replaced. A tire is a circular elastic rubber product assembled on various vehicles or machinery for rolling on the ground.
