Does Using Gas from Small Gas Stations Affect the Car?

What to Do When the Oil Dipstick Smells Like Gasoline?

It should be repaired as soon as possible. The reasons for the gasoline smell in the oil are as follows: 1. The lubricating oil has not been replaced for a long time, resulting in a decrease in the oil film thickness and insufficient piston lubrication. 2. There is damage on the cylinder wall, leading to gas blow-by. 3. The engine has been used continuously for too long, causing the clearance between the piston and cylinder wall to increase. 4. Frequent short-distance driving without warming up the engine, resulting in insufficient time for gasoline to evaporate. Detailed analysis of why the oil smells like gasoline: 1. Long-term failure to replace the lubricating oil leads to a decrease in the oil film thickness and insufficient piston lubrication. Damage on the cylinder wall causes gas blow-by. 2. It may be due to frequent short-distance driving combined with a large amount of cold-start fuel injection, which can easily enter the oil. Additionally, if the car is stopped without sufficient warm-up, the gasoline inside does not have enough time to evaporate. 3. The engine has been used continuously for too long, causing the clearance between the piston and cylinder wall to increase. The only place where engine oil and gasoline come into contact is the combustion chamber. Due to uneven air-fuel mixture and excessive mixture concentration, the pressure in the combustion chamber is always greater than that in the crankcase, causing a small amount of the mixture to enter the crankcase.

What is the normal tire pressure for Emgrand?

The normal tire pressure range for Emgrand is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. Emgrand's TPMS tire pressure monitoring system does not display the specific pressure and temperature values for each tire, but only shows a TPMS warning symbol and an abnormal tire pressure warning symbol. These two symbols are located on the instrument panel below the front of the driver's seat. If the tire pressure monitoring indicator lights up (a yellow symbol, an irregular circle without a seal on top, with four small spikes at the bottom and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, it will trigger an alarm if the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged while driving, it can also cause the tire pressure warning light to illuminate. For sensor damage, the only solution is to replace it with a new component.

How Often Should Motorcycles Undergo Annual Inspection?

For motorcycles within 4 years of use, inspections are required every 2 years. For those reaching or exceeding 4 years, annual inspections are mandatory. During the annual inspection process, the vehicle owner or organization must complete an annual motor vehicle inspection form and submit the motorcycle to a designated location on the date specified by the local vehicle management office. If special circumstances prevent timely participation in the inspection, an extension request should be submitted in advance to the local vehicle management office. Motorcycles, powered by gasoline engines and steered via handlebar-controlled front wheels, are two or three-wheeled vehicles known for their lightweight agility and rapid mobility. They are widely used for patrol duties, passenger/cargo transport, and as sports equipment. Motorcycle categories include street bikes, road racing motorcycles, off-road motorcycles, cruisers, and tourers.
