Can I Mix Half 92 and Half 98?

92-octane gasoline and 98-octane gasoline should not be mixed. Long-term mixing of different octane ratings will affect the lifespan of the car's ignition system, fuel injectors, and spark plugs, leading to earlier major repairs. The type of gasoline to be used should strictly follow the maintenance manual and user manual. Below are the hazards of mixing gasoline: Mixing higher-octane gasoline into a vehicle designed for lower octane will not cause damage, but the increase in octane rating will alter the fuel's ignition point, resulting in delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, and the actual feedback will be poorer performance. Using lower-octane gasoline in a vehicle designed for higher octane will cause engine knocking. Because the octane rating is too low, the gasoline will ignite prematurely during the compression stroke. If combustion occurs before the spark plug fires during the compression stroke, resistance will arise during the upward stroke. If noticeable knocking is felt, it indicates severe engine conditions. The vibrations not only affect driving stability but also cause abnormal wear on the pistons and cylinders, and in severe cases, can lead to cylinder scoring.

Is it normal for the handbrake to have up and down play after being released?

It is not normal for the handbrake to have up and down play after being released. How the handbrake works: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Reasons for a loose handbrake: The reasons for a loose handbrake include pulling the handbrake too hard. Since mechanical handbrakes rely on springs to return to position, if the spring is repeatedly stretched to its limit, it can undergo plastic deformation, resulting in incomplete return. Another reason is using the handbrake to slow down while driving. Additionally, applying the handbrake when parking in snowy conditions can cause issues. In extremely cold winter regions, unless parking on a slope, it's advisable not to use the handbrake because the mechanical components can freeze, especially during wet and snowy weather, making it difficult to release the handbrake once engaged.

What are the reasons for the loud engine noise after refueling at a small gas station?

The reasons for the loud engine noise after refueling at a small gas station may include overfilling the fuel tank, engine overheating leading to loss of power, etc. Overfilling the fuel tank: After overfilling, the instantaneous working resistance of the engine increases, which raises the crankshaft's rotational resistance, reduces the engine's output power, and allows excess fuel to enter the combustion chamber and participate in combustion. The result is oil burning, blue smoke emission, and increased fuel consumption. Engine overheating: Engine overheating leads to a loss of power. When the engine operates for an extended period, its surface becomes excessively hot, and the cooling system fails. In this case, the first step is to check the cooling system. If there is a problem with the cooling system, it may cause exhaust blockage because the vacuum tube is likely to break. At this point, steam or hot air will escape from the engine, producing some loud noises.

Why Can't a Motorcycle Start When It's Hot?

There are many reasons why a motorcycle may fail to start when hot, as detailed below: Reasons for failure to start: Specific reasons include the starter motor rotating too slowly or slipping; faulty coolant temperature sensor; insufficient fuel pressure; faulty fuel injector; clogged air filter; whether the spark plug electrode gap is normal and if there is carbon buildup. Analysis of motorcycle ignition methods to determine the cause of failure to start: Motorcycle ignition methods include electric start and kick start. Electric start usually fires up the engine in one go. If it doesn't start after two or three attempts, avoid using the electric start further, as repeatedly using the electric start without success can drain the battery and damage it. Instead, use the kick start. In winter, when temperatures are lower, it may be harder to start the engine. In such cases, adjust the choke lever—normally it should be pressed all the way down. For cold starts in winter, pull the lever all the way up. After the engine starts, leave it in the middle position for about 15 seconds. Once the motorcycle has warmed up, return the choke lever to the normal position by pressing it all the way down.

Should the steering wheel be turned in the direction the car is pulling?

Under normal circumstances, the steering wheel should be turned in the opposite direction of where the car is pulling. This is necessary to keep the car moving in a straight line. Here are some driving tips: 1. Gear shifting techniques: Do not wait until the RPM is too low and the car has almost no power before downshifting, as this will increase the engine's burden. It is essential to maintain a certain driving force and speed for the vehicle and reduce the engine's load by downshifting early, especially when going uphill, driving at low speeds, or carrying heavy loads. 2. Throttle control: This is essentially a practice in the sensitivity of the foot. When parked in neutral, try pressing the throttle while seeing if you can keep the RPM fixed at a certain level. Once mastered, you can practice this while driving, as the first gear has a high speed ratio (similar to a long lever arm), making the throttle most sensitive and difficult to control. 3. Timing of gear shifting: Gear shifting is a manual action to change the gear ratio of the transmission to adapt to different road conditions and driving performance. Downshifting is suitable for overtaking and downhill driving (engine braking), while upshifting is suitable for high-speed driving, reducing RPM, and lessening the engine's load.
