What kind of oil is used for oil mops for car cleaning?

Why does the car suddenly stall and fail to start?

The car suddenly stalling and failing to start can be caused by several reasons: a dead battery, obstructed fuel flow (avoid waiting until the fuel is almost empty to refuel), poor ignition system performance. It could also be due to starter motor failure, fuel pump or injector issues, sensor malfunctions, etc. For these more complex situations, professional assistance is required. Below are more related explanations: Reasons why the car suddenly stalls and fails to start: 1. Fuel exhaustion: Failing to monitor the fuel tank usage, with the fuel gauge showing below the red line, naturally makes it impossible to start. 2. Dead battery: This could be due to leaving the headlights on for an extended period or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle electrical circuit issues. Checking for a dead battery is simple—just press the horn to find out. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start. If it is in R (Reverse) or D (Drive), the car will not start. Some manual transmission vehicles may also fail to start if the clutch is not depressed.

Is a Fuel Consumption of 9.0 High?

Normally, a fuel consumption of 9.0 is considered average for most vehicle models. Below is a brief introduction about gasoline: 1. Basic Information: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. 2. Composition: The main components are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 89, 90, 92, 93, 95, 97, and 98 based on octane ratings. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95.

Will it have any impact if I suddenly switch from Sinopec to PetroChina?

This will not have any impact. Compared to PetroChina, Sinopec's fuel uses higher-priced additives during the refining process, resulting in a purer final product. For vehicles, this is better because higher purity means the fuel burns more efficiently. However, since both companies adhere to the same final gasoline standards, mixing them poses no issues. Compared to GB17930—2011, the main changes can be summarized as 'three reductions, two adjustments, and one addition.' Details are as follows: 1. 'Three reductions': The sulfur content limit was reduced from 50μg/g in Phase IV to 10μg/g, an 80% decrease; the manganese concentration limit was reduced from 8mg/L in Phase IV to 2mg/L, prohibiting the artificial addition of manganese-containing additives; and the olefin content was reduced from 28% in Phase IV to 24%. 2. 'Two adjustments': Adjustments were made to vapor pressure and fuel grades. The lower limit of winter vapor pressure was increased from 42kPa in Phase IV to 45kPa, while the upper limit of summer vapor pressure was reduced from 68kPa in Phase IV to 65kPa, with Guangdong, Guangxi, and Hainan required to follow summer vapor pressure year-round. Additionally, considering the reduction in octane levels due to lower sulfur and banned manganese content, as well as the shortage of high-octane resources domestically, the standard adjusted gasoline grades from 90, 93, and 97 to 89, 92, and 95, respectively, based on the realities of the refining industry. 3. 'One addition': The standard's appendix now includes technical requirements and testing methods for 98-octane gasoline (V). It is estimated that implementing 'Automotive Gasoline' (GB17930—2013) will significantly reduce vehicle pollutant emissions, with an annual reduction of approximately 300,000 tons of nitrogen oxides for in-use vehicles and a cumulative reduction of about 90,000 tons over five years for new vehicles.

What is the reason for always hitting the right corner when reversing into the garage?

When reversing into the garage on the right side and always hitting the right corner, the reason is turning the steering wheel to the right too early during the reversing process. Normally, you should quickly turn the steering wheel to the right when the lower edge of the side mirror reaches the parking line, which is the so-called reference point for turning right when reversing into the garage. However, due to factors such as vehicle speed, distance from the side line when parking, and the speed of turning the steering wheel, it is not possible to perfectly reverse into the garage every time by turning the steering wheel at the reference point. Here is additional information: 1. Turning right too early when reversing into the garage can be anticipated and corrected. 2. Observe the position between the car body and the right corner of the garage: When reversing into the garage and turning right too early, you can observe the position between the car body and the right corner of the garage. Normally, the distance between the car body and the right corner should be maintained at 30 centimeters to ensure that the distance between the car body and the side lines on both sides is approximately equal. If the steering wheel is turned too early, the distance between the car body and the right corner will be less than 30 centimeters, or even close to hitting the right corner. The standard width of the garage line is 15 centimeters, so in the side mirror, when the distance between the car body and the garage corner is about twice the width of the side line, it is approximately 30 centimeters.

How much fuel is consumed if a car is left idling for 2 hours?

Fuel consumption varies depending on the car brand. Generally, cars with an engine displacement below 2.5L consume between 1~2L per hour, meaning 2~4L of fuel for two hours. For example, a Range Rover 5.0L supercharged version can consume up to 6.0L. Ways to reduce fuel consumption: 1. Properly adjust tire pressure: Maintaining the correct tire pressure reduces rolling resistance and lowers fuel consumption. Additionally, slightly increasing tire pressure by +0.2bar above the recommended value can also save fuel. 2. Use auxiliary electrical devices moderately: Some electrical devices, such as the air conditioning system's cooling function, significantly increase fuel consumption. Turn off seat heaters once the desired warmth is achieved, and deactivate the rear window defroster when there is no fog or ice. 3. Shift gears correctly: Match the gear to the appropriate speed—avoid driving at high speeds in low gears or low speeds in high gears. Shift gears in advance, ensuring the gear matches the speed, and never drive at high speeds in low gears or low speeds in high gears.
