The difference between 95 and 92 gasoline mainly lies in the different proportions of chemical substances they contain, resulting in variations in octane number, fuel consumption, and price. Below is an introduction to the differences between 92 and 95 gasoline: 1. Octane Number Ratio: 92 gasoline consists of 92% isooctane and 8% n-heptane; 95 gasoline consists of 95% isooctane and 5% n-heptane. The higher the octane number, the better the anti-knock performance. 2. Price: 92 gasoline is slightly cheaper than 95 gasoline. 3. Fuel Consumption: 92 gasoline has relatively poor anti-knock performance, so its ignition timing needs to be delayed, leading to faster fuel consumption in the car. 95 gasoline has relatively strong anti-knock performance, resulting in slower fuel consumption in the car. 4. Applicable Compression Ratio: 92 gasoline is suitable for engines with a compression ratio between 8.6 and 9.9. 95 gasoline is suitable for engines with a compression ratio between 10.0 and 11.5.

Does insurance cover a replacement car for repairs?

During the warranty period of household automotive products, if the repair time (including waiting for spare parts) exceeds 5 days due to product quality issues, the 4S store is required to provide a replacement vehicle or reasonable transportation cost compensation. Usage of replacement vehicles: A replacement vehicle during claims refers to the service where the insurance company provides a vehicle to the car owner when their private car is under repair and unavailable. For example, Pacific Insurance and Aodi Car Rental offer "claim replacement car services" for car owners to use. However, typically, insurance companies do not include replacement car coverage in their auto insurance policies. There is only an additional "repair period cost compensation" rider that pays based on repair days to cover replacement car expenses and operational losses. The compensation standard is agreed upon at the time of insurance purchase, but ready-to-use replacement cars are provided, making insurance company replacement vehicles available. Conditions for using a replacement vehicle: The car must be purchased at the dealership and insured with designated insurance companies (e.g., PICC Insurance, Pacific Insurance). Customers who purchase insurance without premium discounts (non-concessional customers). Vehicle owners who need to simultaneously insure against car damage and third-party liability insurance.

Does the Harley X48 have ABS?

Harley X48 has ABS. The ABS sensor is located on the inner side of the car tire, which can be seen by lifting the car. ABS, the full name is Anti-lock Braking System (Antilock Brake System). Its function is to automatically control the braking force of the brake during car braking, so that the wheels are not locked and remain in a state of rolling and sliding (the slip rate is about 20%), to ensure that the adhesion between the wheels and the ground is at its maximum. Working principle: During braking, ABS quickly determines the locking state of the wheels based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that is starting to lock, and keeps the braking force unchanged. If the wheel continues to lock, the normally closed output solenoid valve is opened, and the braking pressure on this wheel rapidly decreases due to the direct connection to the brake fluid reservoir, preventing the wheel from being completely locked due to excessive braking force. This keeps the braking state always at the optimal point (slip rate S is 20%), achieving the best braking effect and the safest driving.

Does the Mercedes HOLD Function Damage the Car?

Mercedes' HOLD function does not damage the car. The HOLD function is activated when the vehicle comes to a complete stop after the first brake application, and then the brake pedal is pressed a bit deeper. This creates extra pressure, but its purpose is to send a signal to the pressure sensor in the control unit, which is the signal to activate the HOLD function. It does not have any impact on the brake discs. Below is an introduction to Mercedes-Benz cars: 1.
