How Long Can Mineral Oil Be Used?

Mineral oil should be changed every six months or 5,000 kilometers, semi-synthetic oil every six months or 7,500 kilometers, and full synthetic oil every year or 10,000 kilometers. Mineral oil: Replace around 5,000 kilometers. Currently, oil prices are generally quite affordable, but mineral oil has relatively poor lubrication performance and shorter lifespan, so it is not recommended. Additional information about engine oil is as follows: 1. Synthetic oil can operate in a wider temperature range: It has a longer service life but comes at a higher cost. For the same oil film requirements, synthetic oil can achieve the goal with lower viscosity, whereas mineral oil requires a higher viscosity to meet the same standards. In other words, under the same working conditions, synthetic oil can protect the engine with lower viscosity. Similarly, in the same working environment, synthetic oil lasts much longer than mineral oil. Although the initial cost is higher, considering the reduced frequency of oil changes, the overall cost is not significantly higher than mineral oil. 2. Mineral oil: It is relatively inexpensive and provides basic protection. Semi-synthetic oil offers better lubrication and cleaning performance at a reasonable price, making it a cost-effective choice that provides excellent protection for regular cars. Full synthetic oil delivers superior lubrication for the engine, with outstanding performance in both high and low temperatures and high-speed lubrication. It is suitable for high-end cars, racing vehicles, and cars operating in extreme climates, but its price is several times that of mineral oil. 3. Replacement intervals: Mineral oil is recommended to be replaced every 5,000 kilometers; semi-synthetic oil every 7,500 kilometers; and synthetic oil every 10,000 kilometers.

Should You Press the Clutch When Decelerating in Subject Three?

The method to determine whether to press the clutch when decelerating is as follows: If the speed is higher than third gear, there is no need to press the clutch; simply use the 'tap brake' method, which involves pressing and releasing the brake pedal. If the speed slows down and the gear is in 2nd or 1st gear, and you feel a lack of power, not pressing the clutch while braking will directly shut off the engine. In this case, the student should simultaneously press both the brake and clutch. The correct method for decelerating in Subject Three: On flat roads with few vehicles, when the speed is above 30km/h and only a short brake is needed, lightly tap the brake pedal without pressing the clutch pedal. When passing bus stops, school zones, waiting at traffic lights, in traffic jams, or parking... these situations require shifting into a lower gear while pressing both the clutch and brake pedals. How to coordinate the clutch and brake: Automatic transmission cars do not have a clutch pedal, so you can directly press the brake. When driving at high speed or normal speed and only needing to slow down, there is no need to press the clutch. When taking a curve, first press the brake to decelerate; after the curve, if there are no obstacles, you don’t need to press the clutch—release the brake and press the accelerator to speed up. If there is an obstacle right after the curve, press the clutch and shift into a lower gear.

Why does the left rear wheel hit the left corner when reversing into the left parking space?

The specific reasons and solutions for the left rear wheel hitting the left corner when reversing into the left parking space are as follows: 1. Steering too early: If you start turning the steering wheel fully to the left before the lower edge of the rearview mirror aligns with the stop line, it can cause the left rear wheel to hit the left corner of the parking space. Solution: When you see the lower edge of the left rearview mirror align with the entrance line of the parking space, press the brake to stop the vehicle. 2. Keeping the steering wheel fully turned to the left: Before reversing into the parking space, you need to align the vehicle 1500-1800mm away from the road edge line (the distance between the car body and the road edge line should be 1500-1800mm), but it's not always possible to stop accurately every time. When you start reversing with the steering wheel fully turned to the left, observe the distance between the left rear wheel and the corner of the parking space in the left rearview mirror. If this distance is less than 300mm (less than 2 fingers in the mirror), you need to adjust the steering wheel to increase the distance. If you keep the steering wheel fully turned to the left, the wheel will hit the corner line. Solution: When reversing with the steering wheel fully turned to the left, if you see that the distance between the left rear wheel and the corner of the parking space is slightly less than 3mm, you can turn the steering wheel back half a turn. If the wheel is about to hit the corner, you can only straighten the steering wheel to increase the distance.

What Are the Reasons for a Car Losing Power After Ignition?

Consider the following reasons if your car loses power after ignition: 1. Check the battery: Most modern cars use maintenance-free batteries, but it's still necessary to periodically check the power level indicator. Generally, green indicates normal power, white means it needs charging or maintenance, and red signifies the battery is dead (some indicators may show green for good condition, black for low power, and white for battery damage requiring replacement). The typical lifespan of a battery is around two years. If the battery power is found to be low, it should be replaced promptly. 2. Inspect the throttle body and idle valve: Carbon buildup in the throttle body or idle valve can cause difficulty starting. For vehicles with an idle valve, lightly pressing the accelerator while starting may help, but the engine may stall immediately after releasing the pedal. Therefore, it's best to have them cleaned and inspected at a repair shop. Additionally, during maintenance, regularly replace the air filter. In northern areas with dusty air, the air filter should be replaced every 10,000 kilometers, or even sooner if driving on sandy or dusty roads. 3. Fuel pressure: To ensure normal engine startup, the residual fuel pressure in the fuel system after the engine is turned off should not drop below 2.5–3.5 kg/cm². Otherwise, insufficient pressure will prevent the fuel injectors from delivering enough fuel for startup. Repeatedly turning the ignition switch can help restore normal fuel pressure, making it easier to start. However, it's advisable to have a professional mechanic inspect the fuel system to diagnose and fix any issues. 4. Lubricant quality: In winter, it's essential to change all lubricants, including engine oil, transmission fluid, and power steering fluid. Regular lubricants thicken in cold weather, reducing flow and increasing friction resistance, making cold starts difficult. Opt for lower-viscosity oil to reduce mechanical wear and protect the engine.

Should the Baojun 730 use 92 or 95 octane gasoline?

The Baojun 730 can use 92 octane gasoline. This octane rating is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, the recommended octane rating is also indicated on the fuel tank cap. Generally, the required gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is even higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the required gasoline grade, as high-compression engines can also be tuned to use lower-octane fuel. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, higher-octane gasoline has a higher octane rating and better anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Baojun 730 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the tank is empty. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles designed for lower-octane fuel, using higher-octane gasoline will not cause damage, but the increased octane rating may alter the fuel's ignition point, leading to delayed combustion. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher-octane fuel, using lower-octane gasoline can cause engine knocking. Due to the significantly lower octane rating, the fuel may ignite prematurely during the compression stroke, creating resistance before the spark plug fires. This resistance can make the engine run very unevenly. Mild knocking may only increase noise without noticeable engine damage, but severe knocking indicates serious engine issues, affecting driving stability and causing abnormal wear to pistons and cylinders, potentially leading to cylinder scoring.

Do manual transmission cars have TCU?

Manual transmission cars do not have TCU, only automatic transmission cars do. TCU is the automatic transmission regulation system. The transmission control module helps the transmission decide when and how to shift gears by collecting information from various sensors and the engine control module, thereby improving vehicle performance, ensuring smooth gear shifts, and saving fuel consumption. The TCU terminal device can wirelessly transmit GPS location information, driving speed, and vehicle data back to the system platform, allowing users to monitor and manage the vehicle via computers or mobile phones. TCU utilizes computer and power electronic drive technology to achieve automatic vehicle transmission, eliminating differences in driver shifting techniques, reducing driver workload, enhancing driving safety, and improving vehicle power and fuel efficiency.
