95 and 98 gasoline can be mixed Knowing

To figure out whether the two grades of gasoline can be mixed, first of all to understand the meaning of the gasoline grade: 95, 98 gasoline, that is, the octane number of gasoline is ≥ 95, 98, respectively, which in the National V gasoline standards clearly stipulated. But 95, 98 is how to come it is the gasoline component of the different resulting. Now if you if Baidu this problem, will say no, but did not detail why.

I tried to analyze the composition of the gasoline, the level of limitations, inaccurate if the connoisseur see don't laugh.

Now China's gasoline pool composition is mainly catalytic cracked gasoline, reformed gasoline, isomerization, aromatization, alkylated gasoline, MTBE, and naphtha components, the gasoline producers are basically the same, the octane number were: 90-91, 102-104, 84-92, 92-94, 95-96, 115, 55-65, gasoline is the factory will be the When gasoline leaves the factory, the above components are blended proportionally, and different ratios are used according to different target products.MTBE, as a high-octane component, can generally be blended into the maximum amount of 13%, and if more, the oxygen content of the gasoline exceeds the upper limit of 2.7% of the national standard, and at the same time, etherified gasoline as a blending component, then the MTBE has to be further reduced. Catalytic gasoline is rich in olefins, reforming and aromatization is rich in aromatics, so there is a maximum blending amount to comply with national standards, to put it bluntly, it is a numbers game, which can be seen, in our country, the higher the gasoline grade, which contains aromatics, generally speaking, the density of gasoline is also large, and the lower the grade, the higher the content of olefins, the worse the stability, not to mention the Sinopec PetroChina, a kind of. At the same time, the octane number of the analytical error is large, the same oil, different laboratories to do samples can be a difference of 0.5, but the gap between the profits of the two oils is huge, so you understand why they are publicizing the non-mixable, right?

So, can not be mixed, not the oil to decide, from the composition, there is no problem, especially 95he98, mixing the results of the oil composition is more reasonable, just octane rating to determine the mixing ratio.

Oil finished, and then say the vehicle, if your car is not bad, at the same time you are not a racer, there is no problem, not to mention what the ignition system, said the mysterious one B, people also eat grains, but also can be more precise than the people

Of course, I decided that the most can decide whether to mix is, who is bored to this gas port queue half a day to add 15 liters, and then change the place to add 20 liters? We all have busy schedules, so let's not add to it.
