Overfilling engine oil can cause the following effects: 1. Reduced vehicle power; 2. Increased fuel consumption; 3. Severe damage to the three-way catalytic converter; 4. Accelerated aging of vehicle components. The solution for overfilled engine oil is: Pull out the engine oil dipstick, which has MIN and MAX markings indicating the lower and upper limits of oil level. Add oil if the level is below the MIN mark, but do not add if it's above the MAX mark - instead, remove the excess oil. Engine oil is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers.

Should You Turn Off the Air Conditioning When Exiting the Car?

You should turn off the air conditioning when exiting the car. Here are the reasons why you should turn off the air conditioning when exiting the car: Reason 1: After the engine is turned off, it cannot drive the compressor, so the air conditioning cannot provide cooling. Keeping the air conditioning on after turning off the engine will reduce the battery's lifespan. Reason 2: The air conditioning increases the load when starting the car. Reason 3: Moisture and mold in the air conditioning ducts can cause unpleasant odors in the car. Turning off the air conditioning 1-2 minutes before parking allows a large amount of outside air to dry the ducts, preventing musty odors caused by moisture and mold.

Will Insurance Cover the Car if It's Flooded in Heavy Rain?

Whether insurance covers a car flooded in heavy rain depends on the following scenarios: Stalling and getting flooded during driving: If you have vehicle damage insurance, but the car stalls and gets flooded while driving through water, coverage depends on the extent of the vehicle damage. Parked state: If you have vehicle damage insurance and the car is flooded while parked (e.g., in a garage or parking lot), coverage depends on the degree of damage to the car. No water ingress insurance: If you have water ingress insurance, the insurance company will cover the damage. Without water ingress insurance, only parts other than the engine may be covered. Restarting after stalling: If the car stalls in water and is restarted, resulting in damage, the insurance company will not cover the loss due to the restart. After the car is flooded, you can file a claim through vehicle damage insurance. After the incident, the owner should not attempt to move or start the vehicle but should report the incident to the insurance company immediately.

What Causes Blue Smoke When Going Uphill but Not on Flat Roads?

The phenomenon of blue smoke appearing when going uphill but not on flat roads is generally caused by oil burning. The reasons for this phenomenon are as follows: Thinning of Piston Rings and Cylinder Walls: The most common cause is that, under normal engine operation, the piston rings and cylinder walls, which are in constant relative motion, gradually wear thin over time. This creates a certain gap between the two contact surfaces, allowing engine oil to seep up into the combustion chamber through this gap. Under high temperature and pressure, the oil burns, resulting in blue exhaust emissions. Additionally, the air-fuel mixture may also leak down through the gap between the piston rings and cylinder walls, entering the crankcase. This reduces the engine's compression ratio, leading to a loss of power in the vehicle. Hardening and Cracking of Valve Stem Seals: Another reason is the hardening and cracking of valve stem seals. Engine oil in the valve chamber can seep through these cracks and flow down along the worn valve stems into the combustion chamber, where it is burned off. This causes the vehicle to exhibit blue smoke due to oil consumption.

Is it mandatory to purchase insurance at a 4S store?

Insurance does not have to be purchased at a 4S store. A 4S store is merely a service provider and has no authority to force car owners to buy vehicle insurance. If coercion occurs, consumers can report it to the relevant authorities. Legal provisions: According to the "Automobile Sales Management Measures": Dealers must not restrict consumers to specific providers of auto parts, accessories, financial services, insurance, rescue services, or after-sales services; nor can they force consumers to purchase insurance or require them to use vehicle registration services. Multiple purchasing channels: Car insurance can be purchased through various channels, not just 4S stores. Consumers can buy car insurance through both online and offline channels, as long as the channels are legitimate and qualified.
