How Long Can You Drive After the Oil Light Comes On?

If the oil warning light comes on, the vehicle should not continue to be driven. You should immediately find a safe place to stop without obstructing traffic. Then, attempt to replenish the oil or request roadside assistance. The primary functions of engine oil include the following: lubrication and friction reduction; auxiliary cooling; cleaning; sealing and leak prevention; rust and corrosion protection; and shock absorption. Lubrication and friction reduction: Engine oil forms a protective film between two sliding components, preventing direct friction and ensuring smooth operation. Auxiliary cooling: During engine operation, high temperatures are generated. When oil reaches these operating areas, it absorbs heat and carries it away, aiding in component cooling. Cleaning: Engine oil circulates carbon deposits, sludge, and metal wear particles back to the oil pan, effectively flushing contaminants from engine components. Sealing and leak prevention: Oil forms a seal between piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. Rust and corrosion protection: Lubricating oil adheres to component surfaces, shielding them from water, air, acidic substances, and harmful gases. Shock absorption: During sudden pressure spikes in engine cylinders, oil helps distribute the increased load on pistons, piston rings, connecting rods, and crankshaft bearings, cushioning the impact.

Last time when my oil light came on, I foolishly kept driving to work, only to have the engine seize up halfway, costing me over 20,000 in repairs. Engine oil is the lifeline for an engine, lubricating friction points to prevent wear. The light indicates low oil level or pressure - continuing to drive will cause parts to overheat and fuse together. Once the light comes on, immediately pull over safely and turn off the engine. Check the dipstick to see if oil level is sufficient; if low, try adding some oil. If you hear abnormal noises or smell smoke, absolutely do not restart the engine. Towing to a repair shop is the safest option - just a few more minutes of driving could total the entire engine. Don't try to save time only to spend big money. After years of driving, I've learned this is never to be ignored. It concerns both vehicle longevity and safe driving, especially on highways where pulling over to check is the only right choice. Don't gamble with your wallet or your car.

How to Deal with Flood-Damaged Cars at 4S Stores?

For vehicles severely damaged by flooding that have lost their repair value, the direct option is to scrap them and obtain scrapping subsidies. After undergoing repair treatments, these cars may be sold to store employees at a lower price, with stipulations that the vehicles cannot be resold within a certain period. Usable parts from these cars will be dismantled, serving either as replacement parts or flowing into dismantling yards similar to Chentian. They may also be sold to used car dealers at very low prices, who then perform minimal refurbishments before selling them to consumers at similarly low prices.

How many years of holding a C1 driver's license are required to upgrade to a B2 license?

You can take the test after holding a C1 driver's license for one year. If you pass the test, the vehicle management office will issue a new-level driver's license within 7 working days. The following are the conditions for upgrading from C1 to B2: To add a new permitted vehicle type to an existing motor vehicle driver's license, you must have held the (C1) permitted vehicle type driver's license for more than three years, and within the current scoring cycle to the most recent scoring cycle before applying for the new permitted vehicle type, there must be no record of accumulating 12 penalty points. Only then will the vehicle management office approve the application for the new permitted vehicle type. C1 is one of the codes for permitted vehicle types in a driver's license. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), C1 refers to a driver's license that permits driving small and micro passenger vehicles, light and micro cargo vehicles, as well as light and micro special-purpose vehicles. It also allows driving the permitted vehicle types of C2, C3, and C4. B2 driver's license permits driving heavy and medium-duty cargo vehicles or large, heavy, and medium-duty special-purpose vehicles. Heavy and medium-duty cargo vehicles are mostly trucks, such as the large dump trucks commonly seen on roads, which belong to heavy-duty trucks. Large, heavy, and medium-duty special-purpose vehicles refer to vehicles equipped with special equipment or devices, such as water sprinklers, concrete mixer trucks, fire trucks, etc. Article 14 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" states that for first-time applicants of a motor vehicle driver's license, the permitted vehicle types that can be applied for include city buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, small automatic transmission passenger vehicles for the disabled, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and tramcars. For those who already hold a motor vehicle driver's license and wish to add permitted vehicle types, the additional permitted vehicle types that can be applied for include large passenger vehicles, tractor trucks, city buses, medium-sized passenger vehicles, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and tramcars. Article 15 states that for those who already hold a motor vehicle driver's license and apply to add permitted vehicle types, there must be no record of accumulating 12 penalty points in the current scoring cycle and the most recent scoring cycle before the application. This applies to applications to add medium-sized passenger vehicles, tractor trucks, and large passenger vehicles as permitted vehicle types. The B2 driver's license test consists of four subjects: Subject 1 covers road traffic laws and regulations related to driving motor vehicles, including road traffic rules, traffic violations, traffic signals, and traffic accident handling. Subject 2 involves practical operations such as pole tests, side parking, hill starts, and driving through single-lane bridges for large passenger vehicles, city buses, tractor trucks, and other vehicle types. Subject 3 includes test drive preparations, starting, driving straight, lane changes, gear shifting operations, etc., for large passenger vehicles, city buses, tractor trucks, medium-sized passenger vehicles, and other vehicles. Subject 4 covers safe and civilized driving operation requirements, safe driving knowledge in extreme weather and complex road conditions, and handling knowledge for accidents.

What are the hazards of engine temperature being too high and too low?

Engine temperature being too high and too low have the following hazards respectively: Hazards of being too high: 1. It causes the mechanical properties of metal materials to gradually decrease, leading to deformation and damage; 2. The normal gaps between various components will be disrupted due to thermal expansion of parts; 3. It makes the engine oil viscosity thinner and oxidizes, reducing lubrication and accelerating part wear. Hazards of being too low: 1. It leads to reduced engine power and increased fuel consumption; 2. The viscosity of engine oil increases, causing poor lubrication and accelerating part wear; 3. It destroys the lubricating oil film, speeding up component wear.
