Is it harmful to add 95 oil to a self priming car?

The short-term mixing of gasoline of different grades will not cause great harm to the car, but the long-term mixing will affect the service life of the ignition system, fuel injector and spark nozzle of the car, so that the overhaul time of the vehicle will be advanced.

Strictly speaking, 92 gasoline and 95 can not be mixed, but the chemical composition of the two of them is relatively close in all aspects, strong anti-knocking, the two are generally not a big problem, after mixing different grades of gasoline in a short time, there is generally no need to carry out special maintenance on the vehicle, but it is recommended that the owner should use the corresponding label of gasoline in strict accordance with the requirements of the vehicle itself if conditions permit. ”

If you really want to mix, you should follow the principle of high and not low.

For example, the original 92 oil car with 95 oil will not be a problem, but on the contrary, it may lead to damage to the vehicle, if the car uses low-grade gasoline may cause vehicle knocking, serious may lead to vehicle valve bending, valve cover damage and other problems.

The main difference between No. 92 and No. 93 is that the limit of sulfur content is reduced from 50 milligrams per kilogram to 10 milligrams per kilogram, and the limit of manganese content is reduced from grams per liter to grams per liter. At the same time, the octane number and anti-knock performance of gasoline have been reduced, and the anti-knock index of No. 89, 92, 95 has been revised to "not less than".

Does a high grade equal good motivation? Is a high grade more fuel-efficient?

After gasoline upgrading, why does fuel consumption increase and power shortage? According to the analysis of industry insiders, the upgrade of the quality of national five gasoline oil is accompanied by the adjustment of the label, and the oil label represents the performance of the oil, the higher the label, the higher the octane number, the better the power performance provided for the car, and the lower the fuel consumption. However, with the upgrading of oil quality, the sulfur content is greatly reduced, and at the same time of reducing the sulfur content, part of the octane number needs to be consumed, so the oil label will be slightly reduced, and the fuel consumption required to produce the same kinetic energy will increase slightly.

In the owner's manual of new domestic cars, No. 92 gasoline is recommended. Only in luxury brand models is it recommended to recommend the use of 95 gasoline. And only luxury brands such as Porsche will mainly recommend No. 98 gasoline.

And if it is a self-priming car with a high compression ratio, it is better to add 95 oil. Because the octane number of No. 95 gasoline is higher than that of No. 92 oil, the anti-knock performance will be better, so that the engine knocks less, it will be quieter, and it can also improve the engine power and reduce fuel consumption. So if it's 95 for 92, how much is left to change?

Theoretically, if you change 95 gasoline to 92 gasoline, you only need to drive the vehicle until the fuel gauge light is on, and it can be replaced. However, in fact, if there is no No. 92 oil in the gasoline label specified or recommended by the car manufacturer, it is not recommended to replace it.

This is because after the replacement of the low-grade oil, the non-evaporating gel formed in the low-grade oil will be deposited on the fuel tank, gasoline duct and filter while the vehicle is driving. As a result, the conduit and nozzle are blocked, and the oil supply is interrupted and the vehicle stalls.

Moreover, the octane number of No. 95 gasoline will be higher than that of No. 92 gasoline, so the anti-knock performance is better, but if No. 92 gasoline is added, then the engine may be more prone to deflagration, which will cause some damage to the engine.

There is no harm in adding 95 oil to a self-priming car.

If you have been adding 92 oil before, and you want to change to 95 gasoline temporarily, in fact, this is no problem, but it is not recommended to mix with oil, if you accidentally mix it once or twice, it will not be said to cause fatal harm to the engine. It's not that high-grade gasoline makes the power stronger, the label of gasoline represents the octane number of gasoline.

The higher the designation, the higher the octane number, the better the resistance to knock out of the gasoline. In fact, the gasoline label has nothing to do with whether the fuel is clean or not. No. 95 gasoline itself is about 1 yuan more expensive than No. 92 gasoline.

The cost of fuel per kilometer is actually no different from adding 92 gasoline.
