It is possible to add 95 gasoline after using 98 gasoline, but this should only be done in emergencies and not for prolonged mixed use. 95 gasoline and 98 gasoline have different additives and chemical compositions. Mixing them occasionally will not cause significant harm to the car. If you mix different grades of gasoline in an emergency, there is no need to worry; simply refuel with the appropriate grade later. However, prolonged mixing of different gasoline grades can harm the car's ignition system, fuel injectors, and spark plugs. Gasoline with different octane ratings has varying levels of octane numbers. Higher-grade gasoline has a higher octane number, and gasoline with a higher octane number has better anti-knock performance.

Is the Compulsory Traffic Insurance Label No Longer Required to Be Displayed?

If electronic insurance policies have been implemented locally, it is no longer necessary to display the compulsory traffic insurance label on the vehicle; if electronic policies have not yet been implemented, the compulsory traffic insurance label must still be displayed. According to Article 95 of the Road Traffic Safety Law: If a motor vehicle driven on the road does not display the inspection qualification label or insurance label, or does not carry the vehicle license or driver's license, the traffic management department of the public security authority shall detain the vehicle, notify the party to provide the corresponding license, label, or complete the necessary procedures, and may impose penalties in accordance with Article 90 of this Law (a warning or a fine ranging from 20 to 200 yuan). Compulsory Traffic Insurance for Vehicles: The full name of compulsory traffic insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates for personal injuries, deaths, and property losses of victims (excluding vehicle occupants and the insured) caused by road traffic accidents within the liability limits. The premium is based on the nationally unified standard rates. However, the price of compulsory traffic insurance varies for different vehicle types, mainly influenced by the number of vehicle seats. Compared to the over 20 exemption clauses in commercial third-party liability insurance, compulsory traffic insurance covers a much broader range, including losses caused by intentional actions of the victim, property losses of the insured, related arbitration and litigation costs, and certain indirect losses caused by accidents. Moreover, regardless of whether the insured vehicle is at fault in the accident, compulsory traffic insurance will compensate within the liability limits without any deductible or exemption. Introduction to Electronic Insurance Policies An electronic insurance policy refers to a digital policy issued by an insurance company using digital signature software and enterprise digital certificates compliant with the PKI system, bearing the electronic signature of the insurance company. An insurance policy, abbreviated as a policy, is the official written proof of the insurance contract between the insurer and the insured. The policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the policy serves as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof labels; Time-saving and convenient, not restricted by time or location, with information universally accessible online anytime, quick and easy; Can apply for reissuance or resending, no need to worry about losing it; if a physical copy is needed offline, it can be printed or mailed; Easy management, with electronic unification making it easier for insurance companies and traffic police departments to manage the insurance information of each vehicle.

Is There a Relationship Between the Carbon Canister Solenoid Valve and Fuel Consumption?

The carbon canister solenoid valve is related to fuel consumption. If the carbon canister solenoid valve is faulty, gasoline vapor will evaporate into the cylinder before the vehicle is started, leading to an excessively high concentration of the combustible mixture. This results in what is commonly referred to as 'flooding the cylinder,' which is very fuel-intensive. Additionally, due to the overly rich mixture, incomplete combustion occurs, prompting the engine ECU to make adjustments. This can lead to a leaner fuel injection in the next cycle, but an overly lean mixture also makes complete combustion difficult, thereby increasing fuel consumption. The carbon canister is filled with highly adsorbent activated carbon, and excess gasoline vapor from the fuel tank is directed into the carbon canister via a tube, where it is adsorbed by the activated carbon instead of being released into the atmosphere. When the engine is started, the solenoid valve between the carbon canister and the intake manifold opens, allowing the adsorbed gasoline vapor to be drawn into the cylinder by the vacuum in the intake manifold along with clean air for combustion. This process not only reduces emissions but also lowers fuel consumption.

Does Skipping the Second Maintenance at a 4S Shop Void the Warranty?

Skipping the second maintenance at a 4S shop does not void the warranty. According to the "Regulations on the Administration of Motor Vehicle Maintenance," manufacturers and 4S shops cannot refuse to provide warranty services for vehicles on the grounds that maintenance was not performed at an officially authorized service center. In other words, car owners are free to choose their preferred repair locations. "Regulations on the Administration of Motor Vehicle Maintenance": No organization or individual may block or monopolize the motor vehicle maintenance market. Vehicle owners have the right to independently choose maintenance service providers. Except for automobile manufacturers fulfilling their responsibilities for defective vehicle recalls and the "three guarantees" (repair, replacement, and refund) for vehicle quality, no organization or individual may force or covertly force the designation of maintenance service providers. The regulations encourage motor vehicle maintenance enterprises to adopt intensive, specialized, and chain operations to promote reasonable division of labor and coordinated development in the motor vehicle maintenance industry. Basic Car Maintenance Knowledge: Belt Inspection. When starting the car engine or while driving, if the belt makes noise, it needs to be replaced. Air Filter Inspection. A dirty or clogged air filter can directly lead to increased fuel consumption and poor engine performance. Regularly check the air filter; if it has minimal dust and is not severely clogged, it can be cleaned with high-pressure air from the inside out and reused. A heavily soiled air filter should be replaced promptly. Fuel Filter Inspection. If fuel supply is sluggish, promptly check whether the fuel filter is clogged and replace it if necessary. Engine Coolant Level Check. After the engine has cooled, check that the coolant level is between the full and low marks. If not, immediately add distilled water, purified water, or antifreeze, ensuring the level does not exceed the full mark. Tire Inspection. Tire pressure is directly related to tire safety. Both overinflation and underinflation can lead to adverse effects. In summer, when temperatures are high, tire pressure should be slightly lower, while in winter, when temperatures are low, tire pressure should be adequately higher.

What are the speed ranges for 1st, 2nd, 3rd, and 4th gears?

The speed ranges for 1st, 2nd, 3rd, and 4th gears are as follows: 1. 1st gear is the starting speed, with a range of 0 to 5 kilometers per hour; 2. 2nd gear corresponds to a speed range of 5 to 20 kilometers per hour; 3. 3rd gear corresponds to a speed range of 20 to 40 kilometers per hour; 4. 4th gear corresponds to a speed range of 40 to 60 kilometers per hour. The optimal time to shift gears is when the engine speed reaches 2000 revolutions per minute (rpm), but should not exceed 2500 rpm. For some high-displacement, high-power engines, the maximum efficiency range may be slightly delayed, so shifting around 3000 rpm may be considered. Different vehicles have engines and transmissions that perform differently. Drivers can determine the right time to shift by listening to the engine sound. If the engine sound is dull, it indicates that it's time to upshift. Driving at a low gear with high load increases engine pressure, raises fuel consumption, and significantly impacts both the engine and transmission. Additionally, if the engine speed drops below approximately 1500 rpm, it's time to downshift.

Who is at fault when a left-turning vehicle is hit by a straight-moving vehicle?

A left-turning vehicle is generally at fault when hit by a straight-moving vehicle, except in the following special cases: 1. If the left-turning vehicle is already in the process of turning and the straight-moving vehicle fails to notice and collides with it, the straight-moving vehicle is responsible; 2. If there is a yield sign at the intersection ahead of the straight-moving vehicle and the straight-moving vehicle fails to yield, resulting in a collision with the left-turning vehicle, the straight-moving vehicle is fully at fault; 3. If the straight-moving vehicle runs a red light and collides with a left-turning vehicle that is proceeding normally according to the traffic signal, the straight-moving vehicle is fully at fault. When motor vehicles pass through intersections controlled by traffic signals, they must adhere to the following rules: 1. At intersections with designated lanes, enter the appropriate lane based on the intended direction of travel; 2. Yield to vehicles already inside the intersection when preparing to enter a roundabout; 3. When turning left, activate the turn signal and turn close to the left side of the intersection center point; 4. When turning right and encountering a vehicle in the same lane waiting for a signal, stop and wait in sequence; 5. At intersections without directional signal lights, turning motor vehicles must yield to straight-moving vehicles and pedestrians, and right-turning vehicles from the opposite direction must yield to left-turning vehicles.
