After buying a car, the radius of life expands several times in an instant.
Weekday commuting weekend outings are indeed convenient, but the troubles have also increased at the same time.
Usually, in the face of disorderly oil prices, in the face of complex failures, in the face of the so-called car knowledge of different opinions. So that the owners of the owners have no way to start, many car owners will come to the message area of Tiger to leave a message to ask questions.
Then today, Taige will take you to take stock of some of the car maintenance issues that the owners of the car are most concerned about in 2021.
The 5 most common problems come first to open the road, do a good job of learning posture, all the owners of the throttle to the end, together with thick hair!
"Original engine oil" is so expensive, is it really the best engine oil?
Many times, Tiger will be asked such a question:
What oil, what air filter, what machine filter should I use for this car? Will the supporting things be worse than the original factory? In the Taige industry for so many years, almost every car owner has a similar obsession with the "original factory" mentality, buy accessories to the original factory, change the oil also needs the original factory.
Also supporting LL12, the original Shell FOUNDry price will be much more expensive than commercially available oil
And asked why I believe in the original factory, the answer is also very simple, it is because the manufacturer recommended, and some manufacturers of the original lubricant is also crowned with some well-known brands of high-end series, separately to the car companies to do "exclusive money", giving people a feeling of special car lubricants.
But in fact, most of them are "sky-high oil" and "oil reduction".
To say that the reason is also very simple, the car manufacturer itself is an assembly factory, generally only the frame, chassis, engine, etc. are designed and built by themselves, and 99% of the other parts, including consumables, are tendered, that is, the way of bidding authorization to other parts factories "OEM".
Since it is a procurement, it will definitely involve price issues, generally speaking, the bidding will not be for an oil company alone, but for several manufacturers. As long as the performance of similar goods meets the standard, it must be the lowest price and the most stable source of goods is the optimal solution
Therefore, in order to ensure profits, oil merchants for the sake of aftermarket channels, and product production lines, naturally can not provide the best products as OE as original oil, and OE for profit margins and cost control pressure can not buy the best lubricants as original oil.
Thus, exclusive money, special oil was born.
In terms of marketing, the attribute of "dedicated to cars" can give car owners a strong sense of belonging. (Speaking of separately developed for xx brand)
In fact, oil merchants and car companies are very clear, the so-called special project is actually the same aftermarket products low half grade products, but with such a label, the oil plant can let the owner know their own lubricating oil sub-series, and 4S Group can also buy the "cheapest" lubricating oil through low-cost channel prices, everyone stands and makes money is not good ~ (after all, profit maximization must be the underlying logic of business)
It is very common for the same lubricant to be more than 30% more expensive than the e-commerce price
So don't be superstitious about the so-called "original factory", and there is never a "original factory is the best" statement!
No matter what accessories or consumables, as long as the specifications meet the regulations of the original factory, the level of certification meets the official requirements of the automobile manufacturer, it can be interchangeable and universal!
Unless it is 4S free to send, basically Tiger is recommended, their own research choice is always the best solution!
How many years can the tire run, is it calculated from the ground or from the factory?
Changing tires is the first relatively expensive cost in car maintenance.
Many car owners hope that the longer the tire is used, the better, but when everyone changes the tire, there is a question "how long can a tire be used"? Because the tire itself has a production date, the general owner of the tire is often 3 months -14 months or so, then if the tire service life is 5 years, it will be removed.
So there is a question, whether the tire is calculated from the ground or the factory?
But in fact, the life of the tire is not only based on the use time, which involves two dimensions!
The first is the actual "wear and tear" of the tire.
The tires we buy on the market are summer tires or four-season tires with patterns, and the important indicator of tire wear is the depth of the pattern. The tread of the tires helps to drain water on rainy days and improves the grip.
As the tire use time increases, the pattern will be more and more shallow, and the drainage capacity of the tire will decline significantly. In this case, even if the tire has no other aging conditions, it is also recommended to scrap the tire.
The average owner can identify the degree of tire pattern wear through the triangle symbol on the side of the tire or the word "TWI", which is called the "tire wear indicator". When this "indicator" and the surface of the tire are "flush", it means that the pattern of the tire has reached the limit of use, and what the owner can do is to buy a new tire to replace it as soon as possible.
The second is the "service life" that all car owners care about
Everyone knows that the tire is a rubber product, and the so-called organic matter will naturally have aging problems.
Everyone has played with rubber bands, rubber bands will melt when they encounter oil, and the sun will be crisp. Therefore, the characteristics of rubber are afraid of oil and ultraviolet rays. Tires as vulcanized rubber products, which have a certain natural rubber component, so tires will naturally receive the threat of sunlight and oil immersion.
Everyone knows that the products from the production line cannot be packaged and shipped at the first time, and they must be stored in storage for a period of time. That company will not let its tires that have just rolled off the production line begin to age.
Therefore, according to the characteristics of rubber, set up a special tire warehouse, as long as it is done in a light-proof, dry and ventilated environment, the aging rate of rubber is very slow, slow to a negligible degree!
There have also been test data from professional institutions, and the physical and chemical properties of rubber products stored in normal light protection after 3 years are almost the same as the tires that are newly off the production line.
So the life of the tire can be determined, not according to the factory life to decide, but according to the time of installation to the car to use!
It is usually recommended that those who drive less cars, after the tire is installed on the vehicle, start counting, and after 5 years, they should ask a professional master to check the status of the rubber. If you find that the aging is obvious, you should replace it.
If it's in good condition, then check it every year thereafter to make sure it's safe.
92# car plus 95# oil can be quieter and more fuel-efficient?
Many car owners have heard a theory that the 92 car plus 95 gasoline will be more resistant to burning, the engine vibration will be less, and the power will be better. However, there are also some articles on the Internet that say that high-grade oil is not easy to burn so it is easy to accumulate carbon, and the engine will use high-standard oil for a long time but will cause engine knock damage due to carbon deposition, and use the engine compression ratio to support the so-called argument.
So can a low-standard car add high-standard oil?
The answer is a bit around, depending on whether the manufacturer has helped you to do the labeling!
Most engines have considered the compatibility of various oils at the beginning of development, such as most developed regions in Europe are the world of 98# gasoline, so most of the cars originating from these places will be very widely calibrated fuel.
BMW's previous generation of N55 engines was calibrated from 91# gasoline to 100 #
In general, The Export of Japan and South Korea mainly covers low-cost models, and the other is the "luxury car" of third world countries, so it does not need to be very wide and very high for fuel calibration like Europe.
At this time, even if you add 95 or even 98# gasoline, but the manufacturer has not calibrated you, the engine will still run according to the setting of No. 92 oil.
To sum up, if the tank mouth has the words "Please use unleaded gasoline 92 and above."
This means that this car can use a minimum of 92, and you can accept it if you want to go up, but it can't be lower than him!
So the owners of the car do not feel that the expensive is better, industrial products are not like animals, eat well to grow well, it as long as the usual management is full of regular inspection and maintenance, it can meet the needs of the vast majority of car owners.
The more expensive the spark plug must be ignited, the better, the more fuel-efficient it is?
Many car owners have an idea: the more expensive and high-end the spark plug, the better, because the higher the ignition intensity, the more thoroughly the gasoline can be ignited and burned cleaner.
Theoretically, expensive spark plugs can indeed increase the intensity of the electric spark, thus achieving fuel saving.
But this thing in tiger eyes, more expensive spark plugs but practical application has almost no obvious benefits.
Because most of the current engines use direct injection technology in the cylinder, the "mixed gas" in the cylinder is in a state of "high-speed tumbling flow" (technically called "rolling flow" before ignition), and the flame propagation speed is extremely fast. Therefore, in addition to the slight difficulty of igniting gasoline at low temperatures, once the engine is successfully started and runs smoothly, the energy of the original spark plug is enough.
And the vast majority of car owners will not drive too violently, usually commuting to work for transportation. The engine speed will not exceed 5,000 rpm, and in such a gentle driving environment, the performance of the spark plug will not have much impact on the vehicle!
That expensive spark plug has only one benefit, only one! The more precious the metal material corresponds to the service life. Life arrangement nickel copper < platinum< double platinum< iridium gold< double iridium gold < ruthenium gold, the price span also ranges from 10 yuan - more than 200 yuan / branch.
In summary, as long as it is not the owner of the engine who has had a power upgrade, there is no need to spend more money to buy expensive spark plugs. Expensive may not be the most suitable, but it must be more expensive is not it~
Fuel treasure propaganda can remove carbon deposits, is it an IQ tax?
"Fuel treasure is IQ tax" is almost the most comments that Tiger has seen on the self-media platform
Tiger also saw in the background that many car owners asked the information of fuel treasure, basically two extremes, one is the owner of the fuel treasure when "skin care products", they think that the car can be used well. The other is to resolutely do not use fuel treasure, everything except maintenance is an "IQ tax", and the car is just a "pragmatism" of transportation.
Then, throwing aside the habits and definitions of car owners, whether the fuel treasure has a carbon deposition effect in the end.
First of all, as long as the thermal efficiency is not 100%, all internal combustion engines will definitely produce carbon deposits, and if there is carbon deposition, there will be products to clean the carbon deposits, and the fuel treasure is the mildest kind.
Each time we add gasoline, there is a certain "fuel treasure", but only 50mg per liter of gasoline, this trace amount of added "fuel treasure" can reduce the carbon accumulation after the combustion of heavy substances in the fuel.
Simply put, as long as you increase the amount of "fuel treasure" in gasoline, you can increase the role of cleaning carbon deposits.
The carbon deposits washed off by the fuel treasure will be surrounded by polar substances, and the oil will form a "particulate oil sol" dispersed and suspended in the oil, and finally removed by the machine filter!
Most of the carbon deposits washed by the fuel treasure are removed by circulating filtration after contaminating the oil. And careful masters can go to see, the "clean" fuel treasure on the market does not add any accelerants, and PEA itself is not a combustible substance, so through gasoline atomization, attached to the internal surface of the cylinder to dissolve carbon particles and sludge.
Finally, it was scraped into the crankcase by the "scraping ring" on the piston and dissolved into the oil.
This is completely different from the "work that fuel treasure should do" that you think of
As for many car owners with no feeling, in fact, it is the fuel treasure manufacturer deliberately do, after all, washing too clean will cause damage, slight carbon deposition will increase the sealing of the cylinder, is conducive to engine operation. As a low-cost maintenance method, it is recommended that the owner add it every 5,000 kilometers.
Well, the above five questions and answers are the 5 most "problems" that Tiger has encountered this year.
