How many numbers of gasoline should ordinary cars usually add

Small sedan with naturally aspirated engine The car adds 92-marked gasoline, and the turbocharged-engine car adds 95-labeled gasoline. Drivers who are not familiar with the car engine can also directly read the description of the position of the fuel tank. The fuel label will be marked on the inside of the gasoline cover, and you can refuel as required.

If it is an ordinary naturally aspirated family car, it is enough to use 92 gasoline. If it is a turbocharged car, most of them need to use 95 gasoline, but some cars with turbocharged engines can also use 92 gasoline. You need to look at the fuel tank cap or user manual for the specific gasoline number to use.

Generally, naturally aspirated engines add No. 92 gasoline, and turbocharged engines add No. 95 gasoline. There is no difference in the composition of No. 92 gasoline and No. 95 gasoline. They are all based on No. 90 crude oil. The only difference between the two is that the octane number is different. The octane number is different, and the explosion resistance is different.

Private cars generally add 92. Under normal circumstances, the recommended gasoline will be marked next to the fuel tank cap of the car, and the car's instruction manual will also be recommended for car refueling.Add 92 gasoline to the ordinary naturally aspirated engine, and 95 gasoline to the turbocharged engine. The compression ratio of the engine is between 0-5 and No. 92 gasoline.

In fact, the vehicle needs to add No. 92 or No. 95 gasoline, and there are no relevant regulations or requirements. For private cars, according to the manufacturer's recommended requirements for adding oil products, most of them require the addition of No. 92 or above unleaded gasoline. There are also some luxury brand cars that require the addition of No. 95 and above unleaded gasoline.

Cars with ordinary naturally aspirated engines do not have high requirements for fuel. In general, adding No. 92 gasoline can meet the needs of the engine. Cars with high turbocharged or compression ratio are suitable for No. 95 gasoline. High-end luxury or high-horsepower cars have high requirements for fuel quality, so No. 98 gasoline is added.

Which is better, Shell gasoline or Sinopec gasoline

Sinopec gasoline is better. Ingredients and additives: Shell gasoline has a wide range of crude oil sources, including domestic and imported crude oil, so its quality is relatively stable. The additives of Shell gasoline are the latest, which can clean the engine and improve the combustion efficiency of fuel.

The two brands of gasoline, Shell and Sinopec, are relatively more resistant to Sinopec. The quality of Sinopec fuel will be better, mainly in terms of burning resistance, and the vehicles filled with Sinopec fuel will be sharper and more powerful when speeding up, so it is very easy to complete overtaking.

Sinopec. According to Baidu's driving information, ZhongshiThe quality of chemical fuel will be better, mainly in terms of burning resistance. Sinopec fuel is very fire-resistant, and vehicles filled with Sinopec fuel will be sharper and more powerful when speeding up, so it is very easy to complete overtaking.

PetroChina is good. Compared with Shell's oil, PetroChina's oil will be better. PetroChina is an enterprise directly under the State Council and one of the world's top 500 enterprises. There is strict quality control, and there will be no inferior gasoline such as mixed gasoline, blended gasoline, dirty oil, etc.

Sinopec is good. The two brands of gasoline, Shell and Sinopec, are relatively more resistant to Sinopec. Generally speaking, the burning resistance of gasoline under the same standard is very close, and there will be no obvious difference.

Sinopec gasoline is better in terms of burn resistance and fuel quality. In particular, vehicles filled with Sinopec fuel will be more powerful when speeding up, and it will be easier to overtake.Sinopec's gas stations are relatively widely distributed and can also be easily found in townships, while Shell's are mainly distributed in big cities.

What's the difference between different models of gasoline

1. The octane number is different: No. 89 gasoline comes with 89 % isooctane; No. 92 gasoline contains 92% isooctane;No. 95 gasoline contains 95% isoctane; No. 98 gasoline contains 98% isooctane. The explosion resistance is different: the higher the model of car gasoline, the higher the composition of isooctane, the stronger the explosion resistance.

2. The price is different. No. 92 gasoline is cheaper than No. 95 gasoline. At present, the fuel of regular gas stations comes from Sinopec and PetroChina (commonly known as "two barrels of oil"). Even some private gas stations, the fuel is not produced by itself, but is imported from two barrels of oil.

3. The difference between the three gasolines of #90, #93 and #97 you asked is that gasoline contains isooctane and n-heptane content. The gasoline mark is the ratio of the explosion resistance of actual gasoline to the explosion resistance of standard gasoline. The higher the label, the stronger the explosion resistance. Standard gasoline is composed of isooctane and n-heptane.

4. Different models of gasoline are different in terms of combustion speed and explosion resistance of gasoline. The specific contents are as follows: Combustion rate: The fuel mark, that is, the octane number, is a monotonous upward curve, which has no functional correspondence with the compression ratio. The higher the fuel grade, the slower the combustion speed, and the lower the combustion explosion, so the engine needs a higher compression ratio.

What kind of oil is used in car

1. Five kinds. Oil, brake fluid, fuel oil, transmission fluid and steering assistance fluid. Among them, brake fluid achieves braking by uniformly transmitting pressure, which has four functions: energy transfer, heat dissipation, anti-corrosion and anti-rust and lubrication.

2. Transmission oil: Transmission oil is an oil supply that keeps the gearing system clean, which can ensure the normal operation of the gearbox and help extend the life of the transmission equipment.

3. Automotive lubricants include engine oil, transmission fluid, brake fluid and automotive grease. Among them, the transmission oil includes automatic transmission oil and gear oil, and the automatic transmission oil can be used in direction assistance.

What number of gasoline should be added to the car

Check the instructions for use of the car, and the instruction manual records what number of gasoline should be added to the car. The fuel label will be indicated on the fuel tank cap, and it will recommend how many gasoline you to add. What number of gasoline is better? At present, there are 3 gasoline license plates in China's country (IV), namely No. 90, No. 93 and No. 97.

The following is a detailed introduction to the method of checking the gasoline label: Instructions: Check the car's instruction manual, which records how much gasoline should be added to the car.Fuel tank marking: The fuel tank cap will be marked with the fuel tank number, and the recommended gasoline number, especially the gasoline number.

Check the car instruction manual, which records what number of gasoline the car should be refueled. The fuel label will be indicated on the fuel tank cap, and the number of gasoline will be recommended for you to add, and which number of gasoline is better.

Generally, the larger the compression ratio, the higher the required gasoline label. Generally, if the compression ratio is 5-0, gasoline for No. 90-93 should be selected; if the compression ratio is 0-5, gasoline for No. 90-93 should be selected; if the compression ratio is 5-0, the gasoline for No. 93-95 should be selected; if the compression ratio is 5-0, the gasoline for No. 95-97 should be selected.
