CNOOC does not harm cars. Introduction to CNOOC: CNOOC oil is not harmful to vehicles. It is similar to petroleum, but they should not be mixed. CNOOC oil is petroleum extracted from the sea, but it is recommended not to mix them. There is essentially no fundamental difference between using petroleum and CNOOC oil for cars. The so-called petroleum is a type of combustible liquid, a general term for gasoline and diesel. Quality assurance of CNOOC: CNOOC is a large state-owned enterprise (central enterprise) directly under the supervision of the State-owned Assets Supervision and Administration Commission of the State Council of China. In terms of oil quality, it strictly adheres to national standards in production and plays a leading role in oil quality upgrades. The composition of CNOOC oil and Sinopec oil is almost the same, with the same standards for the components and proportions used in vehicle oil processing, only the production locations are different.

I've been driving for over a decade and have used various gasoline brands, including CNOOC several times. I really don't think it damages the car. The engine runs smoothly, accelerates steadily, and there's no abnormal noise. Friends often say cheap gas isn't good, but I believe the key lies in the legitimacy of the gas station. CNOOC is a major company, and its fuel products meet national standards—they wouldn't deliberately use inferior fuel to harm cars. Older cars require extra attention; I maintain mine regularly, changing the oil and filters to ensure the fuel system stays clean. If there were issues with the gasoline, common symptoms would be increased carbon buildup or unusual exhaust odors, neither of which I've encountered. It's cost-effective, much cheaper than imported brands, saving money that can be spent on parts. I recommend choosing reputable gas stations over sketchy ones to save a few bucks. Combine that with good driving habits, and your car's lifespan will naturally extend—why worry about the brand?

As a young car owner who recently purchased a vehicle, I often refuel at CNOOC stations for affordability. After over half a year of driving, my engine runs perfectly fine. Some claim it harms the car, but my research shows CNOOC, like Sinopec and PetroChina, supplies standardized fuel with additives to prevent carbon buildup and improve combustion efficiency, posing minimal risk to engines. My daily fuel consumption remains stable, and urban driving feels smooth—if the fuel were problematic, the check engine light would have activated. However, I emphasize choosing officially certified stations to avoid adulterated fuel from small vendors. Additionally, matching the gasoline grade to your car model is crucial; my vehicle runs flawlessly on 92-octane. For maintenance, I inspect spark plugs and the fuel tank every 5,000 km to ensure system health, keeping the engine risk-free for a worry-free drive.

As an automotive enthusiast, I've studied gasoline composition. CNOOC's fuel meets quality standards with proper octane ratings that won't easily damage engines. In usage, it controls carbon deposits well and meets exhaust emission requirements. However, using substandard fuel may cause engine knocking, so choosing major brands is crucial. My daily driving experience has been excellent with responsive acceleration and stable fuel consumption. I recommend sticking to consistent gas stations to minimize frequent fuel changes, along with regular fuel injector cleaning. Overall it's safe and reliable - don't let rumors affect your driving confidence.

What Causes Problems with the Forklift Steering Wheel?

There are several reasons why a forklift steering wheel may become heavy: Insufficient power steering fluid: Power steering fluid is a medium oil used in the vehicle's power steering pump, serving to transmit steering force and provide cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the power steering fluid is insufficient, the steering wheel will become heavy. Low tire pressure: Low tire pressure increases the contact area between the tire and the road surface, leading to greater friction and making steering more difficult. This results in a heavy steering wheel, which is detrimental to driving safety. Toe-in: Toe-in affects the vehicle's steering by helping the steering wheels automatically return to the center, ensuring stable straight-line driving. Issues in this area can also cause the steering wheel to feel heavy. Steering gear or power steering pump failure: The steering gear and power steering pump also influence the vehicle's steering. Any malfunction in these critical components can make steering difficult. Problems such as universal joint issues, chassis suspension stabilizer bar problems, or plain bearing failures should not be overlooked.

How many times should the hazard lights be flashed in Subject 3?

In Subject 3, the hazard lights should be flashed twice. The first time is when passing through an intersection, and the second time is when encountering an oncoming vehicle that fails to switch from high beam to low beam promptly after you've done so. Below is an introduction to hazard lights: Hazard Lights: They indicate that the vehicle has a minor operational issue, preventing it from accelerating or speeding normally, and serve as a warning to following vehicles to drive safely and yield appropriately. Traffic Regulations: In the event of a breakdown or accident on the highway, the hazard warning lights must be activated. At night, the width lights and tail lights should also be turned on simultaneously. When the light switch is turned to the first position, the small lights that illuminate both front and rear are the width lights. These indicate the width of the vehicle and alert other drivers. The emergency lights, which involve both small lights flashing simultaneously, are used to signal passing vehicles to exercise caution. Hazard lights are typically used in foggy or heavy rain conditions, vehicle breakdowns, or other emergencies.

Which Item Should Be Practiced First in Subject Two?

Subject Two begins with learning the structure of the vehicle, adjusting the driver's seat and rearview mirrors, and fastening the seatbelt before driving. The Subject Two exam consists of five items, each with numerous reference points. Due to differences in height and weight, the reference points vary from person to person. When the instructor asks you to perform a specific action at a certain moment, it is crucial to identify your own reference points and reflect deeply. Practicing driving is not always about quantity; it should not be done blindly but with thoughtful reflection. Below is a detailed introduction to the mnemonic for the Subject Two lighting test: Turning on the Turn Signal: Subject Two emphasizes turn signals; remember them well and don't forget. Ignition and Starting: Don't rush when igniting and starting; turn on the left turn signal in sequence. Parallel Parking: When exiting during parallel parking, and also during right-angle turns. Left Signal On: Only proceed when the left signal is on, and don't forget hill starts.
