First of all, Qiqi is a brand that focuses on the innovation of automobile maintenance products. Committed to providing China car owners with more cost-effective products. "First-line performance" and "reasonable price" are their goals. At present, Kiki's main products are engine oil products. Today, Dahuyou will explore the ins and outs of Qiqi engine oil.
The driving oil comes from the world's top oil companies.
According to the in-depth understanding of the visit, Dayouyou learned that the driving oil is actually closely related to a world-renowned lubricant manufacturer in Korea. This enterprise is one of the "two barrels of oil" of the famous SK Group in South Korea. (Basically, the most gas stations in Korea are either GS or SK. These two companies are the largest petrochemical giants in Korea and are called "two barrels of oil" in Korea. )
In fact, there are many "red to purple" brands in the world, and China people don't know much about them. For example, we mentioned SK today. SK Group has been deeply involved in the China market for many years, focusing on providing high-quality base oil. Then this gallop is the finished oil after deep cooperation with South Korea SK.
We know that the composition of engine oil is base oil+additives. More than 70% of finished engine oil is basically base oil, and the content of good base oil will even reach 80%, so the performance of base oil itself often directly determines the grade of engine oil. In the simplest metaphor, the essence of chicken soup is definitely the old hen herself, not ginger, onion, garlic, salt and seasoning.
Driving a golden bucket,
Real top engine oil!
So what kind of engine oil product is driving engine oil? Dahu oil has also been investigated: at present, Chi Jia brand engine oil is mainly divided into two grades, of which the main market is the "grey barrel" series with "YUBASE imported fully synthetic base oil" as the core; The main high-end market is the "golden barrel" series with "four types of high-end base oils of PAO" as the core.
Anyone who knows engine oil knows that engine oil base oil is mainly divided into five categories: 1 The second category is mineral oil, which is the lowest end. The third category is "hydrocracking oil" or "special process dewaxing oil" and "various natural gas synthetic oils", etc ... This family has the largest scale and complex technology. The fifth category is lipids, which are common in basic sports, but rarely seen in the field of family cars.
And what is the "Grade 4 oil" of the "Golden Barrel" series? I think if you know engine oil, you don't need my science. How did the fame of four base oils, poly-α-olefins, come from? -Extremely stable ultra-high viscosity value, ultra-high temperature oxidation resistance, excellent pour point performance ... Needless to say, it is synonymous with top engine oil!
The "golden bucket" is at the top,
"Grey bucket" faces the public
Of course, PAO base oil will definitely be associated with "expensive". After all, the production cost of PAO base oil is very high, so only top engine oil will directly use PAO as base oil. However, it is impossible for a brand to have only top-grade engine oil products, and it is bound to take into account the "more popular" market. This is the "grey bucket" series products.
Although the "grey barrel" series is slightly weaker than the "PAO golden barrel" on the tall platform, the base oil of the "grey barrel" series is by no means ordinary. The "grey barrel" series base oil is still supplied by SK of Korea, and the patent "YUBASE imported synthetic base oil" is adopted.
The Golden Bucket &; "ash bucket",
Different certifications are suitable for different models.
In fact, South Korea SK itself is the world's top base oil supplier, and this YUBASE base oil has actually been adopted by major first-line engine oil brands around the world. This base oil has an ultra-high viscosity index (the viscosity index of ordinary lubricating oil is about 120, while the viscosity index of "YUBASE" is as high as 140), which gives the engine oil excellent low-temperature starting and high-temperature protection capabilities.
The "YUBASE Oil" produced by UCO process based on SK Group's patent has a unique molecular structure of full reaction chain, which means that the molecular arrangement is more "regular". We know that this is also one of the characteristics of synthetic engine oil, which can effectively control the wear of parts and ensure fuel economy.
At the same time, the content of alkanes and heterocyclic aromatic hydrocarbons in engine oil is extremely low, so it has good oxidation resistance, which means longer oil change cycle and longer maintenance interval. For car owners, this is actually to save money! Of course, the level certification corresponding to "golden bucket" and "grey bucket" is also different.
The "golden bucket" mainly corresponds to the strict European standard ACEA standards and factory certification of Volkswagen and Mercedes-Benz, so the "golden bucket" is very suitable for European models; The whole series of "ash hopper" has passed the SN-PLUS certification, which effectively solves the low-speed pre-combustion problem of high-power turbine direct injection engine and is very suitable for Japanese and Korean models.
"Barrel"&; "vial",
Different packaging, different engine oil quality?
I think the difference between "golden bucket" and "grey bucket" is basically clear. Next, an interesting question is discussed: What is the difference between "big barrel" and "small bottle" of engine oil? Do bottles with different capacities mean that the quality of oil in the bottles is different? Because I noticed that some so-called "experts" in the workshop misled the riders, I felt it necessary to talk about it. First of all, the big fool affirmed: no matter what packaging, the oil inside is actually the same thing!
"Barrel" generally corresponds to 4L capacity, and "vial" generally is1L. Why are there such "rules"? It's simple! Because most small-displacement engines change oil almost every 3~4L, the industry-unified 4L barrel of oil is used up at one time, with little waste.
However, many large-displacement engines often change 4~5L oil every time because of the large oil pan capacity. At this time, "a vat"+"a small bottle" is actually just right. If you buy two "vats", there will be a lot of oil left, which will lead to waste. But if you buy five "small bottles" directly, you will find that the price is not cost-effective because of the packaging cost. Speaking of which, I think you are smart enough to understand why the "rules" are like this?
