Consequences of overfilling engine oil: 1. Causes blue smoke from the engine exhaust pipe, which means burning oil; 2. May lead to piston ring seizure, fuel injector clogging, and other faults. Excessive oil can be forced into the combustion chamber and burned, forming carbon deposits on the piston rings, piston tops, valve seats, and fuel injectors, resulting in wear between the piston and cylinder; 3. Excessively high oil levels can generate oil mist when agitated by the connecting rod big end, which may ignite upon encountering high temperatures, causing crankcase explosions; 4. Too much oil increases the pressure in the lubrication system, making oil seals prone to damage and leading to oil leaks.

Will the Battery Die If I Run the Air Conditioner with the Engine Off?

Running the air conditioner with the engine off will drain the battery. Here are the related details: 1. Risk One: A chronically undercharged battery poses driving hazards to consumers. It creates safety risks by affecting the brightness of headlights and the sound of the horn, impacting safety. Secondly, it damages the vehicle's powertrain system. Repeated ignition attempts will significantly accelerate engine wear, potentially leading to poor engine starting, unstable idling, and sluggish acceleration. 2. Risk Two: Thirdly, it harms onboard electronics. Unstable voltage can greatly affect electronic devices (such as GPS, audio systems, etc.), even causing device damage. Fourthly, it may result in the loss of computer data. A completely dead battery (power failure) can cause the loss of stored data in the vehicle's computer, and the cost of re-unlocking is expensive, time-consuming, and labor-intensive. Lastly, it may lead to an inability to start the vehicle, resulting in a breakdown on the road.

What to Do When Car Screws Are Too Tight to Loosen?

You can spray rust remover at the screw's interface or directly apply lubricating oil, then use a wrench to rotate it. Below are some solutions for screws that are too tight to loosen: 1. Use Tools: If the screw is too tight, brute force won't help. Instead, use tools like a wrench and pliers. Clamp the screw with pliers, then tap the screw's end with the wrench's head to create some gap, making it slightly loose. Then, leverage the principle of leverage to potentially loosen the screw. 2. Apply Lubricating Oil: Sometimes, rust makes screws hard to loosen. Spray rust remover or apply lubricating oil at the screw's interface, then use a wrench to rotate it. 3. Heat Application: Another method for rusted screws is heating. Use a gas welding flame to heat the screw thoroughly until it turns red, then apply engine oil. The goal is to use thermal expansion and contraction to increase the gap between the nut and the screw, making it easier to loosen.
