It is recommended to change the automatic transmission fluid every two years or every 40,000 kilometers driven. The potential hazards of not changing the transmission fluid are as follows: 1. Transmission fluid working under high-speed and high-temperature conditions for a long time will deteriorate and volatilize, thereby aggravating the wear of mechanical parts and, in severe cases, damaging internal transmission components. 2. If the transmission fluid is not changed for a long time, the car may experience weak starting when cold. 3. The vehicle is prone to slight slipping and similar phenomena during driving. 4. Long-term failure to change the transmission fluid will cause it to become thicker, which can easily block the transmission cooler, leading to excessively high transmission fluid temperatures and increased wear.

What to Do If You Accidentally Fuel with 95 Instead of 92?

92 mixed with 95 has no significant impact and may even improve power output. Here are the relevant details:1. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through distillation and cracking, used as fuel.2. Differences: The octane rating indicates anti-knock performance—higher numbers denote better knock resistance. Composition varies: 92-octane consists of 92% isooctane and 8% n-heptane, while 95-octane contains 95% isooctane and 5% n-heptane. The slightly higher cost of 95-octane reflects its greater isooctane proportion.

What are the problems with flood-damaged cars?

Flood-damaged cars can have various issues affecting their electronic control systems, engines, interior materials, and wiring systems. A flood-damaged car refers to a vehicle that has been submerged in water. The internal electronic control systems may suffer damage, as rainwater mixed with contaminants is highly corrosive, potentially impairing electrical functions and future usability. Never attempt to start or crank the engine of a flood-damaged car, as this can cause severe deformation of the engine connecting rods. Interior components like carpets and seats may become deformed, rough, or develop odors due to prolonged soaking, leading to bacterial growth. Wiring may short-circuit due to moisture. Methods to identify a flood-damaged car: Inspect the engine bay: Even after cleaning, traces of mud or water stains may remain on some wiring harnesses if the vehicle was submerged. Check the interior: If the interior was flooded, the car would have been dried out. Look for signs of wrinkling or other irregularities on seats that may indicate water damage. Examine metal components under the interior: For example, check under the seats for rust on springs or support rods, which could indicate flood damage (though poor rustproofing by the manufacturer is also a possibility). Inspect seat belts: Pull out all seat belts fully to check for mold or dampness. If multiple belts show these signs, the car was likely flooded. Check sealed areas between components: Since interior parts are tightly fitted together, mud residue in these areas may indicate water damage. Inspect the undercarriage: The undercarriage provides the most direct evidence of a car's condition. Look for obvious rust, which would be quite noticeable if the undercarriage was submerged for an extended period.
