What grade is Castrol DX?

Castrol DX is an SN-grade fully synthetic engine oil, and the DX oil is specifically designed for the General Motors series. This oil has excellent lubrication performance. The selection methods for engine oil and brands are as follows: Engine oil selection method: Naturally aspirated engines have relatively modest requirements for oil quality and can use mineral oil or semi-synthetic oil. If the owner has a higher budget, fully synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate in harsher conditions, requiring higher-performance oil with better fluidity. Fully synthetic oil is recommended. Brand selection method: For choosing a lubricant brand, if you prioritize long oil life, you can choose Mobil lubricants; if you prioritize the oil's cleaning ability for the engine, Shell oil is recommended; if you need lubricants with strong oil film toughness, Castrol is a good choice. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell oil with strong cleaning ability can be selected.

Which Gear is the Low Gear?

Low gear and high gear are relative concepts without a unified definition. In China, based on road conditions, it is customary to refer to first, second, third, and reverse gears as low gears, while gears above fourth are called high gears. Below is relevant information: Waterlogged roads: When driving through waterlogged sections, promptly shift to a low gear and press the accelerator pedal firmly to maintain high engine RPM and torque, ensuring sufficient power to overcome water resistance and underwater obstacles while reducing wheel slip and preventing water from backflowing into the exhaust pipe. [3] Bumpy roads: On uneven or potholed roads, using a low gear at idle or with slight acceleration can minimize the impact of rough terrain and reduce body vibrations. 3: Speed-restricted roads: In areas with low speed limits, such as military zones or residential neighborhoods, using a low gear prevents excessive speed from continuous acceleration. Even if the accelerator is mistakenly pressed, the speed typically remains comparable to a fast-pedaling bicycle. For leisurely driving or sightseeing, low gears also enable slow coasting, easing the driver's burden.

Can the unallocated amount in Sinopec fuel cards be refunded?

The unallocated funds in Sinopec fuel cards can be transferred to the corresponding bank card but cannot be withdrawn in cash. For fuel cards, allocation refers to transferring the funds deposited in the user's account to the fuel card before they can be used. In simpler terms, money is deposited into the main card at a service outlet and then distributed to the subsidiary cards. Since the subsidiary cards are held by the drivers of the vehicles, the allocation is completed by having the gas station staff swipe the card during refueling. Below is additional information: Benefits of allocation: At the time, gas station systems were outdated, and real-time communication was not feasible. The allocation function allowed direct deductions from the fuel card without needing to retrieve data from a server. The fuel card's data is stored in its IC chip, and any changes are recorded in a database. Explanation of allocation: Allocation transforms the traditional method of withdrawing cash from a bank account and carrying it for payments into directly transferring (allocating) funds from the bank account to an IC chip, effectively creating an electronic wallet. This eliminates the risks associated with carrying cash, such as needing change, loss, counterfeit money, or theft.

What Does an Optional Package Mean?

An optional package is a combination of configurations that car owners can choose based on their needs when purchasing a vehicle, aiming to ensure that every feature in the car is "worth the price and fully utilized." In fact, purchasing optional packages is a very common consumer concept in the developed automotive markets of Europe and America. The following are the precautions when picking up a new car: 1. Verify contract information: When signing the contract, check whether the vehicle information and the promises made by the dealership are consistent. Other content can be ignored as it is mostly standardized. 2. Choose an insurance company: Generally, there are several insurance companies to choose from at the 4S store. Basic insurance includes (compulsory traffic insurance, vehicle damage insurance, third-party liability insurance, and vehicle and vessel tax). Other types of insurance can be purchased according to personal requirements. The new version of insurance includes glass insurance, spontaneous combustion insurance, and water damage insurance. 3. Select a license plate number: There are no additional fees except for the official cost. Remember to refuse any unauthorized charges during the process. There are only two ways to choose a license plate: self-selection/random selection.

Can You Drive When the Engine Oil Is Below the Minimum Mark?

If the engine oil level is below the minimum mark, you should immediately stop driving, turn off the engine, and wait for assistance. Continuing to drive under such conditions can cause severe engine damage. Below are the hazards associated with oil levels below the minimum mark and overfilling: Hazards of Oil Level Below the Minimum Mark: If the oil level is just below the minimum mark, the crankshaft may not reach the oil, preventing lubrication of the cylinder walls and piston pins, which accelerates wear. If the oil level decreases further, the oil pump may also fail to reach the oil. Once the oil pump cannot draw oil, all parts of the engine requiring lubrication will be deprived of oil, leading to engine damage within minutes. Hazards of Overfilling Oil: Overfilling causes a larger portion of the crankshaft to immerse in the oil, making rotation more strenuous due to increased oil resistance. This results in higher fuel consumption and symptoms such as sluggish acceleration and engine choking.

Does It Consume Fuel Without Pressing the Accelerator?

It does consume fuel even without pressing the accelerator. To keep the engine running, a certain amount of fuel must be consumed; otherwise, the car will stall. For example, when the car is idling in neutral, the engine maintains idle rotation, during which the system still requires a small amount of fuel injection. Therefore, under normal circumstances, the fuel injection process continues. Below are some driving tips: Check the rearview mirrors: Always use turn signals and slow down when turning or changing lanes; always check the rearview mirrors before turning. Left turns mainly require checking the left rearview mirror, right turns mainly the right rearview mirror, and both left and right turns require checking the interior rearview mirror. Don't stare at the front of the car: When driving on a clear road, look straight ahead at about 100 meters, not at the immediate front of the car. Press the clutch: Generally, when decelerating at speeds above 40 km/h, there's no need to press the clutch first; press it when the speed drops to around 20 km/h. Steering: Turn the wheel slowly for high-speed turns and quickly for low-speed turns.
