I've always been at Tuhu Car Wash.
A few days ago, after the car wash coupon was cancelled, I saw that Tuhu happened to have a wave of 399 minus 20 and full 699 minus 50 activities, so I swiped the app for a while. I saw one during this timeTuhu's 2023 annual car maintenance list, and there is one of themList of motor oilsSuccess caught my attention.
The engine oil list can be subdivided into:Word-of-mouth list, value gang, repurchase list, hot list, popularity listandNew Power List6 major sections, each of which lists five star products
As a long-time veteran driver who has been maintaining the Tuhu factory store for a long time, out of curiosity, I made a simple statistic of the brands on the list:
A total of 6 brands appeared in the list, except:Mobil, CastrolwithShellIn addition to these three traditional Haoqiang, the more eye-catching ones in the list are also the key brands of TuhuRidewithHoneywell。In addition, there is a relatively niche brand on the list-Saipai
What's even more surprising is that among the 13 specific products nominated for 30 times in the list, the highest frequency is not any of the Megashells, butPioneering, nominated a total of 4 times. And then there'sCastrol Extreme Protective Pleasure EditionShell High Efficiency Power (Gold), Honeywell 9 Series, Honeywell H8, Honeywell H7andRide the classic, the above 6 models have been nominated 3 times each.
Taking advantage of this very interesting list of Tuhu, and also taking advantage of the year-end promotion, I will talk to you about these engine oils on the pound list, and at the same time share the purchase skills of engine oil.
To talk about the performance and purchase that you have, you must first understand a few basic concepts.
Many people only know the term engine oil, and they also know that they have to be replaced every time they maintain it, but they don't know what engine oil is and what its functions are.
The so-called engine oil is, in essenceLubricants。But it does much more than thatLubricationIt's so simple, and at the same time it's affordableClean, cool, seal, rust preventionand so on.
Since it is a lubricant, we have the following two requirements for its performance:
Fluidity should be good when the temperature is low, otherwise the loss of fluidity in winter will lead to damage to the dry grinding of the engine - corresponding to low-temperature fluidity ;
When the temperature is high, it should not become too thinOtherwise, it will not be able to adhere to the surface of the part like water, and it will also lose its lubricating effect - corresponding to high temperature viscosity.
This part of the basics will be used in the following section of designators.
When it comes to motor oil, one concept that can't be avoided is labeling.
In the diagram above, the meanings of the letters s and n are clearly identified in the diagram, and there is nothing to expand on. The most important thing to focus on is the two numbers before and after the letter w
The letter w is an abbreviation for the English word winter. The number 5 in front of w representsLow temperature fluidity, the lower the number, the better；The following number 30 representsHigh temperature viscosity, the higher the number, the better
In other words,The larger the difference between the two figures, the wider the temperature range of the oil, and the better the performance of the oil- But this does not mean that the difference in the oil label used in a good car is necessarily greater - for example, the engine requirements for engine oil are different between Japanese and German cars. Even if it is the same German system, the engine oil suitable for BMW and Mercedes-Benz may not be suitable for Audi (there will be examples below).
In addition, it should be emphasized that the number corresponding to the label does not represent the actual applicable temperature, and its correspondence is shown in the figure above
For example, the 5W-30 mentioned above means that it can be used at a minimum of -30 and the kinematic viscosity of the oil is 11 CST when the engine temperature is 100.
First of all, two concepts are clarified:
Engine oil is composed of two parts: base oil and various additives;
The so-called fully synthetic, semi-synthetic and mineral oils refer to base oils
Actually, it correspondsMineral oilAnother noun should be:Synthetic oils
So-calledMineral oil, which is directly extracted from **Pure natural base oils；As the name suggests,Synthetic oilsIt is a manual passChemically produced base oils
With the same grade, mineral oil does not perform as well as synthetic oil-- This is a clear departure from our traditional belief that what is natural is best.
According to the proportion of base oil in the engine oil, three concepts were born: fully synthetic, semi-synthetic and mineral oil.
To put it bluntly,Fully synthetic motor oil stands for high-quality motor oil
After understanding the above points, we can analyze several products on the list in detail.
There are a total of 6 brands on the list, in addition to the more familiar big three Mejiake, there are also two rookies: Honeywell and Jiachi, and another more niche brand - Saipai.
Let's briefly sort out the product lines of various brands of engine oil in the following content, so that you can choose according to the map.
Shell's motor oils are familiar to everyone, and the product grades are differentiated according to the color of the packaging
Basically all the information on the Internet says that Shell engine oil is divided into gray shell, blue shell, yellow shell, red shell and white shell according to the grade from high to low. But after in-depth understanding of various e-commerce channels, I didn't find a white shell product, but on top of the gray shell, there is also a gold shell - such as the Shell high-efficiency power (gold) in the list.
among othersGolden ShellwithGray shellAll belong to the fully synthetic motor oil;Blue shellIt is a semi-synthetic motor oil;Yellow shellHX6 is a semi-synthetic oil and HX5 is a mineral oilRed ShellIt's all mineral oil.
In the list mentioned above, Shell has three products on the list, namely Shell High Efficiency Power (Gold), Shell New High Efficiency Power (Gray) and Shell High Efficiency Engine (Blue Shell), all of which are fully synthetic engine oils.
Castrol's oil grades are classified from highest to lowest:Extreme protection, magnetic protection, and carewithJialiFour grades, the first three are common.
among othersExtreme ProtectionwithMagnetic protectionIt is a fully synthetic motor oil;JiahuIt is a semi-synthetic motor oil;JialiIt belongs to mineral engine oil. Castrol Extreme Comfort is the only model on the list, a fully synthetic motor oil that has been nominated three times.
There are three grades of Mobil motor oils, from highest to lowest: Mobil 1, Mobil Super and Mobil Liberty. Among them, the most familiar Mobil 1 can be subdivided into Gold Mobil, Silver Mobil and Green Mobil.
Classified according to fully synthetic and mineral oilsMobil 1withMobil SupermasterAll belong to the fully synthetic motor oil, whileMobil LibaIt belongs to the low-end range of mineral engine oils.
Honeywell's brand should not need me to introduce more, it belongs to a proper multi-field omnibious giant, from heaven to earth, omnipotent.
Honeywell is also one of the manufacturers of turbochargers for automobiles, and to say that it doesn't understand turbocharged engines is the biggest joke of the century. It can make superchargers, and lubricating oil in the petrochemical industry is naturally not a problem.
Compared with the classification of the Big Three, Honeywell's naming is much more intuitive, and the whole series of products can be divided into:9 series, H8, H7, H6andh5A total of 5 series. The higher the series number, the higher the rank. Among them, the 9 series can be divided into H9 and V9 - and the base oil of V9 is the well-known PAO fully synthetic oil.
5 series: 9 series, h8andh7All belong to the full synthetic motor oil, if subdivided, the 9 series and H8 belong to the high-end fully synthetic motor oil, and the H7 belongs to the mainstream full synthetic motor oil;h6withh5It is a semi-synthetic motor oil;That's right, Honeywell has phased out low-end mineral oils.
Another thing that needs to be mentioned in particular is,Honeywell H6 and above series engine oils can be used in China VI emission standard vehicles.
The three products on the list are: Honeywell 9 Series, Honeywell H8 and Honeywell H7, all of which are fully synthetic motor oils, and each of the three products has been nominated three times. It can be seen that in the field of high-end engine oil, Honeywell has the strength to compete with the Big Three, and even in terms of sales, it has surpassed some brands in the Big Three.
Here's a very interesting phenomenon:
The H9-C5 0W-20 in the Honeywell Series 9 is a high-end fully synthetic motor oil, and the basic oil used is a lipid motor oil, which is almost impeccable in terms of quality. However, it was developed for the new European large-displacement luxury engine, so it is more friendly to German car engines, such as Mercedes-Benz E-Class and BMW 5 Series - but it is not suitable for Audi engine maintenance, even the Audi A4, which is one level lower than the Mercedes-Benz E-Class and BMW 5 Series.Why do you want to bring it out to talk about this, in fact, I want to explain a reason:
It is not a high-end car that can be used in engine oil, but it can also be used in a lower-grade car。Each car has its own suitable oil, and you can refer to the vehicle maintenance manual and manual for specific parameters. If you don't want to go deeper, go straightBind the corresponding model in the Tuhu app, and the system will automatically match the appropriate oil and maintenance** for users to choose, which is very worry-free
This is also the advantage of maintenance on an online platform like Tuhu - the system will guide you to standardize maintenance, so you don't have to worry about encountering unprofessional repairmen.
Let's go back to the question above:
What if an Audi owner wants to use Honeywell's high-end motor oil?In fact, just choose H9-C5 0W-40;As for the luxury cars of the United States, Japan and South Korea, as well as the high-end models of Volkswagen and Porsche, you can choose the Honeywell V9 with PAO four base oils.
In a word:Choose the right oil for your car, rather than blindly buying expensive ones
The brand of thinkauto may be a little unfamiliar to everyone, it belongs to the new domestic power of the car maintenance product brand, focusing on intelligent technology maintenance. Its products are involved in all aspects of automobile engine maintenance, air conditioning systems, and batteries, and they are very popular on Tuhu.
According to the grade, the engine oil is divided into three series from high to low, respectivelyultra、pioneerandclassic——The corresponding Chinese names arePrivileged, pioneeringandClassic, which is also very intuitive.
Ride is calledMillet in the car maintenance industry, the corresponding oil maintenance is known for its high cost performance. However, cheap does not mean inferior qualityAll three series of products are fully synthetic motor oilsamong othersUltra PrivilegeThe series is still made of high-quality PAO Class IV base oilspioneerThe series is based on SK VHVI base oilsEven the main cost-effective onesclassicThe series also uses SK Yubase base oils and high-quality additives.
Among the three nominated products, the ULTRA was nominated 1 time;Pioneer has been nominated 4 times, which is the most frequent of all productsThe Classic has been nominated 3 times, and it is also very eye-catching.
In the field of maintenance of low-end models, the engine oil of Jiachi is becoming more and more popular with users with its ultra-high cost performance, and even has a place in the high-end field (Jiachi Ultra Premium).
In terms of brand awareness, Saipai will be more niche. But Saipai is backed by the famous rhinoceros butt - Sinopec Sinopec.
There is very little information about the brand on the Internet, and even the e-commerce desk hardly has much information to refer to, so I can't find any technical information that is too standardized. However, judging from the naming method of the Saipai J600 (full synthesis) on the list, there is a high probability that the series differences are also represented by subtitles or number sequences.
In the Internet era, as the cost of engine oil becomes more and more transparent, the era of four sons lying down to make money is gone. However, the maintenance of roadside shops will face various problems such as shoddy engine oil, or even fake engine oil.
In this context, professional car maintenance platforms such as Tuhu have emerged, which solves the long-term car maintenance problem of the majority of car owners.
As a 13-year driver, I have bought three cars. Because I was afraid of getting out of insurance or vehicle breakdown, I went to the fourth son's store to pay the protection fee obediently like everyone else. But one day after three years of being the unjust leader, I suddenly woke up, and I never went to my fourth son to be slaughtered again.
Of course, the premise that I don't get slaughtered is that I still have a choice, and the maintenance channels other than the fourth son are reliable. Speaking of which, I really want to thank Tuhu, which has saved me a lot of money over the years.
This is the end of this oil purchase class. In the process of sorting out the materials, I also learned new knowledge along the way. I watched the next Tuhu activity, and I happened to participate in the full 399 minus 20, full 699 minus 50 full minus, and friends who have maintenance needs in the near future can pay attention to it.
We do evaluations with attitudes and produce content with temperature. I'm Tomato, we'll see you next time
