92 octane and 95 octane gasoline should not be mixed for long-term use. Relevant explanations are as follows: 1. Long-term mixing may cause knocking, insufficient power, and other issues. Especially for cars designed for 95 octane gasoline, using 92 octane gasoline long-term can increase the frequency of knocking and accelerate engine wear. 2. The octane rating of gasoline represents its anti-knock quality. The higher the octane number, the better the anti-knock performance of the gasoline. Therefore, refueling according to the engine's compression ratio or the requirements specified in the car's manual is more scientific, economical, and can fully utilize the engine's efficiency.

What is the solution for the P0560 fault code?

p0560 fault code solution is: 1. Replace the main relay; 2. Replace the speed sensor. The P0560 fault code refers to a fault in the car's main relay. The main relay of a car is the main power supply relay of the engine control unit, which provides power to the engine control unit. Some vehicles' main relays have a delay function, providing power for a few seconds after the ignition switch is turned off, allowing electrical devices such as the throttle to return to their initial positions. The function of the speed sensor is to detect the engine speed, determine the position of the crankshaft, detect the top dead center signal of the piston and the crankshaft angle signal, and transmit the detected signals to the ECU to control the ignition timing and fuel injection timing.
