Is it ok to mix "petrochina" and "sinopec"?
Petrochina and sinopec are very familiar to those who drive cars. They are closely related to our life. But have you ever thought about whether to add petrochina or sinopec if the car runs out of gas? All have a "in" word which good after all? Or do you want to add that? So how big is the difference? Let's see.
Most of the discovered oil fields in China are located in the northern region, so petrochina has the dominant number of oil fields, but few in the south, so sinopec has more refineries. Moreover, petrochina's refining is dominated by domestic crude oil, while sinopec's own oil resources are limited, so it focuses on refining imported crude oil. And imported crude oil refining is slightly larger than domestic crude oil density, that is to say the same amount of cases, the oil consumption will be quicker, without the use of so-called because density is small but volume, gas station would be more happy, and the owner will consume larger, corresponding cost also will be a little high, namely: sinopec than petrochina's oil "gold content" would be higher, that is more resistant to fire.
From the perspective of superior product density, sinopec's oil products are basically around 0.75-0.77, while petrochina's are around 0.72-0.73. So we can conclude that spoil the petrochina is added in the oil as far as possible, and spoil the sinopec and sinopec as far as possible, mixed with the special situation and is usually not a problem, but after all, a domestic oil refining a imported oil refining, the density of the size is different, is likely to lead to the increase of carbon deposition and vehicle body shaking.
