Is There Any Impact When Mixing 98 and 95 Gasoline?

92 and 95 gasoline should not be mixed because they have different isooctane contents. 92 gasoline is suitable for engines with low compression ratios, while 95 gasoline is suitable for engines with high compression ratios. If 92 gasoline is added to a car that requires 95 gasoline, it may cause abnormal combustion, leading to knocking. Knocking not only damages the combustion chamber but also directly affects the normal operation of the engine, and in severe cases, it may cause engine damage. If 95 gasoline is added to a car that requires 92 gasoline, although it will not damage the engine, 95 gasoline is more expensive than 92 gasoline, resulting in unnecessary costs. Differences between 92, 95, and 98 gasoline: Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, with an octane rating of 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with an octane rating of 0. If the gasoline is labeled as 92, it means that the gasoline has the same anti-knock properties as standard gasoline containing 92% isooctane and 8% n-heptane. The same principle applies to 95 and 98 gasoline. How to handle adding the wrong gasoline: If gasoline with a higher octane rating than required is added, such as adding 95 when 92 is specified, simply switch back to 92 gasoline after the current tank is consumed. If gasoline with a lower octane rating than required is added, such as adding 92 when 95 is specified, you can add a high anti-knock fuel additive. Alternatively, you can drain the incorrect gasoline and refill with the correct 95 gasoline. To find out which gasoline your car requires, refer to the vehicle's user manual or check the fuel grade indicated on the fuel tank cap.

What does the ECO light indicate?

When the ECO indicator light on the car is illuminated, it indicates that the vehicle's economy mode has been activated. ECO stands for the car's economical driving mode, also known as economy mode. When the vehicle frequently operates in congested urban traffic conditions, activating the ECO mode can significantly improve fuel efficiency. Under the ECO mode, the amount of carbon deposits in the engine is roughly the same as that produced under normal operating conditions. The main principle of the ECO mode is not complicated. It primarily involves making comprehensive judgments and analyses of various factors that affect fuel consumption during vehicle movement, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal amount of fuel to be supplied to the engine for operation, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine's speed with appropriate gear positions to minimize unnecessary fuel consumption. ECO is an abbreviation, with the Chinese translation representing Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The ECO mode is further divided into active ECO driving mode and non-active ECO driving mode. When the dashboard ECO indicator light is on, it means the vehicle's economy mode is activated. The ECO mode can be either active or non-active. The difference lies in the fact that the active mode has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode switch, the dashboard indicator light will illuminate, and the vehicle will automatically adjust settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light is on, it serves merely as a reminder function. The ECO system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will synchronously display the ECO indicator light. Most vehicles use the active ECO driving mode, which means they have their own switch button. Therefore, you can enable the ECO mode during daily driving. However, it is unnecessary to activate the ECO mode when the speed exceeds 120 km/h, during idle parking, in N/P gear positions, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of the ECO mode but could also affect the vehicle's power. Additionally, the ECO mode typically becomes ineffective under the following conditions: When the vehicle speed exceeds 120 km/h, the system prioritizes speed, and the ECO mode automatically deactivates. During idle parking or in N/P gear positions and manual mode, the ECO mode may also become ineffective. When high torque output is required, such as when climbing hills, the engine's computer will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will not operate.

What are the differences between National V and National VI standards for the Golf?

The differences between National V and National VI emission standards are as follows: Different emission standards: The National VI emission standard is more than 30% stricter than National V. Excluding the influence of driving conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The National V standard was implemented nationwide on January 1, 2017. The National VI standard has been in effect since July 1, 2019. Different principles: Under National V, diesel and gasoline vehicles had different emission standards, but National VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of fuel type. Different issuing authorities: The National V standard was issued by the Ministry of Environmental Protection, while the National VI standard was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: National V is represented by 'V,' while National VI is represented by 'VI.' Different monitoring requirements for plug-in hybrid electric vehicles (PHEVs): Compared to National V, National VI has enhanced monitoring requirements for PHEVs, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulatory aspects. The National V standard limits are as follows: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM (fine particulate matter) per kilometer driven. National VI has two sub-standards: National VIa and National VIb. Their limits are as follows: National VIa standard limits: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM per kilometer driven. National VIb standard limits: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 mg of PM per kilometer driven. Due to the impact of the National VI emission policy, although National V vehicles are not currently restricted in normal use (no driving bans or plate restrictions), their resale value will be significantly affected. For car owners, if they purchase a truck on loan for cargo transport, the vehicle's depreciation after repaying the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, National VI vehicles, which have a longer lifespan and more road-use privileges, are more advantageous.

What is the tire model of the Livina?

The Livina's tire specifications are 195/55R16 and 185/65R15. In 195/55R16, the first number 195 represents the tire width of 195MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 16 represents the rim diameter of 16 inches. The middle letter "R" stands for radial tire. In 185/65R15, the first number 185 represents the tire width of 185MM, 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width, and 15 represents the rim diameter of 15 inches. The middle letter "R" stands for radial tire. The Livina's tire brands are Dunlop or Bridgestone, and the spare tire specification is non-full size. If you want to replace the tire yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car. The jack should be positioned under the vehicle. Check and ensure the jack is at a right angle to the ground; Remove the hub cover, loosen the nuts counterclockwise. Do not fully loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts, not the tire, are turning; Turn the nuts counterclockwise until they come off. Repeat this step for all lug nuts and completely remove the nuts; Place the new tire on the hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and hand-tighten them until all nuts are concealed. At this point, the tire replacement is complete. In addition to the model, the tire also has the following common data: Tire cord material: represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent the certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: indicates the rim specification compatible with the tire for practical use, such as standard rim 5.00F.
