What Octane Gasoline Should a Normal Car Use?

The selection of gasoline octane rating should be determined by the compression ratio of the car's engine. The appropriate fuel octane rating for the vehicle is usually indicated on the inside of the fuel tank cap. If it specifies 92-octane fuel, then use 92-octane. If it specifies 95-octane fuel, then use 95-octane. Whether the gasoline is 92 or 95 octane, the number represents the fuel's anti-knock performance. A higher octane rating indicates better anti-knock performance, but it does not necessarily mean higher fuel quality, contrary to the common belief that higher octane fuel is always better. For naturally aspirated engines, 92-octane gasoline is generally recommended. Higher-octane fuel has better anti-knock performance but burns relatively slower, which can lead to higher compression ratios in the engine, resulting in reduced power and increased temperatures. For turbocharged engines, manufacturers typically recommend 92-octane or higher. Using 95-octane gasoline not only ensures higher torque at low speeds but also helps reduce engine vibration and noise.

How many kilometers can you drive when the tire wears to the safety line?

Tires should not be driven when they wear to the safety line because at this point, the tire's drainage and grip are very poor, which may lead to loss of control or skidding during driving. It is necessary to replace the tire promptly. The safety line is usually located at the bottom of the tire grooves as a wear indicator. Its purpose is to remind the owner that if the tire tread wears down to this position, the tire must be replaced. The following are precautions for car tire maintenance: Pay attention to tire pressure: Tire pressure is crucial for tires. Both overinflation and underinflation can shorten the tire's lifespan. Underinflation increases tire deformation, leading to cracks on the sidewalls and excessive flexing, which generates heat and accelerates rubber aging, fatigue of the cord layers, and cord breakage. Regularly check front-wheel alignment: Front-wheel alignment significantly affects tire lifespan, with toe-in and camber being the primary factors. Excessive camber mainly accelerates shoulder wear, while incorrect toe-in (too small or too large) primarily accelerates wear on the inner or outer edges of the tire. Be mindful of driving habits: Choose smooth roads while driving to avoid sharp objects like stones, glass, or metal that may puncture or damage the tires. Avoid chemical spills that could adhere to or corrode the tires. When driving on roads with significant curvature, try to stay centered to reduce uneven tire wear caused by increased load on one side.

What to Do About High Fuel Consumption in Nissan Sylphy?

Sylphy high fuel consumption solutions are as follows: 1. Regularly clean the air filter to ensure the engine breathes fresh air and maintains smooth air intake. 2. Periodically inspect and replace spark plugs in the ignition system, as sufficiently strong ignition sparks are essential for complete combustion of the fuel-air mixture. 3. The fuel system should also be cleaned regularly, as carbon buildup on the fuel injectors can cause needle valve sealing issues, leading to fuel leakage. 4. The engine interior should be periodically cleaned of carbon deposits, as excessive carbon buildup can cause inaccurate fuel control, thereby increasing fuel consumption.
