Engine oil, gear oil, or transmission oil can be used. Here is some relevant information about hydraulic oil: 1. Characteristics: It has good anti-foaming properties, ensuring stable power transmission and preventing accelerated oxidation of the hydraulic oil. It also has excellent rust prevention and oxidation stability, making it less prone to oxidation and degradation, thus extending its service life. It has suitable viscosity and good viscosity-temperature performance, enabling accurate and sensitive power transmission while ensuring normal lubrication of hydraulic components. 2. Function: Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays roles in energy transmission, wear resistance, system lubrication, corrosion prevention, rust prevention, and cooling within the hydraulic system.

Back when I operated heavy machinery, the hydraulic oil suddenly ran out. Unable to find the specialized oil immediately, I tried using clean 10W40 engine oil as a temporary solution. It worked barely—the hydraulic pump could still operate, but within just a few days, it started making abnormal noises and leaking. Hydraulic oil is designed to withstand high pressure and resist oxidation, whereas engine oil, despite its higher viscosity, tends to foam and corrode rubber seals. Long-term use of substitutes can lead to system failure. Any alternative should only be considered an emergency fix; always prioritize finding the manufacturer-recommended oil, especially since heavy machinery systems are highly sensitive to contaminants. After that incident, I always carry a spare bottle of professional-grade hydraulic oil to prevent similar emergencies—this directly impacts operational safety and should never be taken lightly.

Does Shifting Gears with the Engine Off Damage the Car?

Shifting gears without pressing the clutch when the engine is off does not have any significant impact on the car. Here are the detailed explanations: 1. Correct Gear Shifting: Turn on the power, press the brake, and shift the gear—not directly into D (Drive) but first into N (Neutral) before starting the engine. Then shift from N to D, release the handbrake, lift the foot brake, and start moving. This avoids the brief reverse impact on the transmission when shifting from P (Park) through R (Reverse) after starting the engine. 2. Gear Shifting for Short Stops: Use the handbrake and shift into N instead of P. Avoid keeping the gear in D while pressing the brake for an extended period (more than 30 seconds). The P position has a locking mechanism; engaging P without applying the handbrake can cause wear on this mechanism. Keeping the gear in D while the vehicle is stationary can lead to transmission wear.

Why Do People Who Drive Roewe Cars Tend to Be Disliked?

Because most Roewe drivers are either unlicensed taxi drivers or ride-hailing drivers, and many of them have rough driving habits, which makes them annoying. Roewe (ROEWE) is an automobile brand under the Shanghai Automotive Industry Corporation (Group), launched in October 2006. Below are some considerations when buying a used Roewe: 1. Age of the Vehicle: Pay attention to the vehicle's age and mileage. Generally, the condition of a used car older than five years will deteriorate progressively. 2. Maintenance Records: Check the vehicle's maintenance records to see if it has been officially serviced at authorized dealerships to avoid high maintenance costs later. 3. Accident History: Also, review the vehicle's accident history by checking its records through a "Used Car Archive" search. Based on the findings, inspect the accident points carefully, and don't forget to take a test drive.

What are the reasons for the Envision's engine revving up but lacking power when accelerating?

The following are the reasons for the engine revving up but lacking power when accelerating: 1. Insufficient fuel pressure, poor fuel pump performance, or clogged fuel filter or injectors. 2. At 3K RPM, the speed should be around 100, but if the car doesn't accelerate and lacks power, it could also be a clutch issue (oil leakage or wear). The problem might be less noticeable when the engine is cold, but as the temperature rises (during driving), the issue may occur more frequently, even leading to a complete "halt" in movement (when the clutch plates are completely burnt out). 3. Throttle body issues, such as sticking or a faulty stepper motor. 4. Exhaust system or catalytic converter blockage. 5. Electrical circuit open or short circuit.

Can a used car purchased from another region be transferred?

Used cars can be transferred across regions. The specific process for transferring a used car from another region involves first obtaining the relevant information about the vehicle, then completing the transaction at the local used car market in the vehicle's original location, where a nationally standardized used car transaction invoice will be issued. After purchasing the vehicle, you need to apply for a transfer of registration at the local vehicle management office where the car is registered. Relevant information about vehicle transfer is as follows: 1. Introduction: Vehicle transfer refers to changing the name of the vehicle's owner. When buying a used car, besides checking the condition of the car, the most important step is completing the transfer procedures. 2. Principle: Every car has a fixed registration, which mainly records the owner and address of the car, as well as some related car parameters. Transferring a car proves that the car belongs to the new owner and has no accidents or violations. If the car has issues, such as being involved in an accident, failing to undergo annual inspection, being stolen, or being smuggled, it cannot be transferred through normal procedures.

How to Quickly Memorize Nighttime Simulated Lighting?

When encountering oncoming traffic, following a vehicle, or driving straight, remember to turn on the low beams; for new turning scenarios, turning on the low beams is sufficient; upon hearing 'pass' or 'overtake', alternate between high and low beams; high beams are only used when illumination is poor; in case of vehicle malfunction or temporary parking, turn on the width and warning lights; if the lighting conditions are the same, stop the operation and listen to the voice prompt; when the test ends with a voice prompt, turn off all lights. Below is an introduction to Subject 3: 1. Introduction: Subject 3 is part of the motor vehicle driver's license assessment, referred to as the road driving skills and safe civilized driving knowledge test. 2. Content: The road driving skills test generally includes: preparation before driving, simulated lighting test, starting, driving straight, gear shifting operations, changing lanes, pulling over, driving straight through intersections, turning at intersections, encountering oncoming traffic, overtaking, making U-turns, and nighttime driving. 3. Assistance: Students can use the mock test software on the Driving Test Guide mobile app or computer to study traffic regulations.

Can You Drive a Manual Transmission Car with an Automatic Transmission License?

An automatic transmission license does not permit driving a manual transmission car. An automatic transmission driver's license is classified as a C2 license. According to China's traffic regulations, a C2 license for small automatic transmission vehicles only allows driving small and micro automatic transmission passenger cars, as well as light and micro automatic transmission cargo vehicles. Driving a manual transmission car with a C2 license is equivalent to driving without a license and will be subject to severe legal penalties. Relevant information about automatic transmission is as follows: 1. Introduction: As the name suggests, an automatic transmission does not require the driver to manually shift gears. The vehicle automatically selects the appropriate gear based on the driving speed and traffic conditions. Typically, an automatic transmission car has six gear positions, arranged from top to bottom as: P, R, N, D, S, L. 2. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, an automatic transmission consumes over 10% more fuel than a manual transmission. Whether manual or automatic, the more gears a transmission has, the more fuel-efficient it is.
