After the oil price "broke 9", what is the mantra of car owners?
92# is full and scary legs are weak
95# Fill up and ruin the family
98# Full, three generations of repayment
······
Gasoline / diesel fee is the main expenditure of fuel owners to maintain a car, in the face of high oil prices, in addition to practicing "golden right foot", in fact, we can also achieve the purpose of fuel saving through "modification and upgrading", is it really so magical?
There are 100 fuel-saving ways to modify the old mage here, but considering the input-output ratio, I still recommend some more grounded fuel-saving Dafa, remember to like and collect, and when you reach out to your daughter-in-law, you will have more confidence.
Weight reduction and fuel saving method
"Wheels, tires, suspension" is a must-have three-piece set for car players, but don't simply think that they only have to improve the handling performance, and the wheels/tires in them are reasonably upgraded to achieve the purpose of saving fuel.
The wheel hub is like the soul of the car, and the wheel hub size plays a key role in the appearance of the vehicle. Although car companies have equipped many popular models with large wheels of 18 inches or more, due to cost constraints, they often use heavier-quality cast large wheels.
The large and heavy cast wheels undoubtedly increase the "rotation inertia", affecting the dynamic reaction of the vehicle, but also increasing the level of fuel consumption; conversely, lightweight wheels can bring fuel saving effects.
Of course, we must solemnly explain that the wheel hub weight reduction is not a sneaky treatment on the spokes of the original wheel hub (extremely unsafe), but under the regulation of "not changing the size and specifications of the original tire", a forged wheel with better mechanical properties is replaced.
Taking the 18-inch wheel hub as an example, the weight of a single cast hub is about 11kg, and the weight of a single piece of a forged hub is about 9kg. As the saying goes, "1kg under the spring 10kg on the spring", that is, 1kg under the spring is equivalent to 10kg on the spring. To put it more in layman's terms, upgrading a set of lightweight wheels of the same size and specifications is equivalent to carrying one less adult man.

But then again, for non-car-playing people, if you upgrade the lightweight wheels for the purpose of saving fuel, then the forged wheels with higher costs are not the best choice.
After the market introduced a spinning technology (a branch of the casting process) between the forging process and the casting process, the wheel hub products were born with extremely cost-effective products.

The most typical representative is Singapore's Advanti (Advanti) KONIG series, which adopts the Japanese ENKEI MAT super spinning technology (has been authorized by technology), the wheels produced by this technology are not only high in strength, but also light in weight, about 15% lighter than ordinary cast wheels, with mechanical properties close to forged wheels, and most importantly, the price is relatively close to the people.

Research data show that the fuel consumption of the car is directly proportional to the quality of the car itself, and for every 10% reduction in the quality of the car, the fuel consumption will be reduced by 6%-10%.
In addition to lightweight wheels can reduce fuel consumption, such as upgrading carbon fiber engine covers, trunk covers, fenders and other body coverings, as well as titanium exhaust systems can effectively reduce body weight and further achieve fuel savings, but these high-priced modifications make civilians prohibitive. Applying for an upgrade fee from your daughter-in-law is all up to your eloquence and knees.
Drag reduction and fuel saving method
At the beginning of the design of tires, engineers gave tires characteristics that can be handled, wear-resistant, or fuel-efficient.
In simple terms, tires can increase or decrease tire rolling resistance by optimizing tire formulation and structural design, and the smaller the roll resistance coefficient, the better the fuel economy.
Following a cost-effective original replacement solution, we found the answer from the 19-inch SUV high-performance tire group in the "2021 China Top Tire Test Ranking", which ranked as follows:
1st place
Hankook S1 evo SUV
(Rolling resistance coefficient 5.89)
Second place
Kumho Echida PS71 SUV
(Rolling resistance coefficient 6.73)
Third place
Tongyiou PROXES Sport SUV
(Roll resistance coefficient 7.61)
Fourth place
玲珑 GRIP MASTER C/S
(Rolling resistance coefficient 8.26)
Fifth place
Zhengxin AD-R9 SUV
(Rolling resistance coefficient 8.68)
From the above, it can be seen that the difference between the first and fifth places of the rolling resistance coefficient is 2.76 times; in terms of price, the price span of the five tires is between 500-1,600 yuan, and the reference price of the cheapest Kumho Wing Chita PS71 SUV is 559 yuan, compared with the first ranked Hankook Wantushi S1 evo SUV, which highlights its own cost performance.

In addition, reducing the wind resistance of the body can also reduce the fuel consumption level, such as removing the original luggage rack, large tail wing and other body protrusions.
It is worth noting that when using a car every day, if the tire pressure is insufficient, it will increase the contact area between the tire and the road surface, and the rolling resistance will increase, thereby increasing fuel consumption. Therefore, it is best to check the tire pressure regularly and inject the right amount of tire gas, which can be more stable and fuel-efficient when driving.
Maintenance and fuel saving method
In fact, the current car has been able to take into account the fuel consumption and power very well, and the most direct impact on fuel consumption is actually the state of the engine, so regularly check and maintain the car, maintain the best state of the engine, and naturally save fuel. Therefore, the owner must regularly check the oil, oil filter and air barrier, and repair it as soon as possible if there is a problem.
There are many oil products with fuel-saving formulas that not only provide high-quality lubrication to keep the engine running smoothly, but also provide excellent fuel efficiency and fuel savings. However, most of the prices are more expensive, and here, we can use the simple and effective method of "full synthetic low viscosity" motor oil, low viscosity can reduce mechanical resistance, and full synthesis can improve viscosity.
In addition, "engine carbon deposition" is a problem that occurs in all gasoline vehicles.
Especially in the congestion of urban areas, the engine is in a low speed for a long time, then, the owner needs to pay attention to and regularly remove carbon deposits, there are the following 3 reference methods.
First, in the case of legal compliance and safety, the vehicle will be driven at high speed, while the engine speed will rise, removing some of the vehicle carbon deposits;
Second, engine decarbonization is achieved through car care services that remove carbon deposits from hydrogen.
Third, buy gasoline cleaners, do it yourself, and eat well.
Let's talk a little bit about the most convenient and fast third method of decarbonization.
Gasoline cleaner, as the name suggests, is to pour a bottle before refueling, it is sent to the inside of the engine through the oil duct and fuel injector, which plays the role of cleaning carbon deposits, and by the way, the oil channel and the fuel injector are dredged together, killing three birds with one stone.
There are many gasoline cleaners on the market to choose from, before buying, many people will ignore a key word, it is PEA (Chinese name: polyetheramine), almost all additives to achieve cleaning effect depends on it. It can realize the dissolution and peeling of carbon deposits and oil stains, is a safe and effective carbon deposit cleaning agent, and its formulation ratio also directly affects the ability to clean up carbon deposits.
Of course, high concentrations of PEA can also have negative effects, such as jitter, knocking, combustion efficiency, running texture and so on.
From the current personal experience, the "DDR poison" launched by the Japanese HKS modification brand is very recommended, its PEA content is as high as 75%, and it also has the advantages of "carbon removal + increase power", which has a very wide popularity in the car play industry. The price is not expensive, and it has a strong reputation for "decarbonization", which shows that HKS is very experienced in its grasp of PEA formulations.

epilogue
As the saying goes, "a modification is as deep as the sea, and from then on the wallet is a passerby", but the modification plan introduced today, in addition to looking good and easy to open, is more important to save money. "Other people modify the cost, I modify to save fuel!" This way the modification is more convenient to apply for the fee with the wife!
As oil prices soar to historic highs, electric vehicle prices rise like a tide, and new energy subsidies may be cancelled next year, and on the whole, the cost of replacing cars will gradually increase. Therefore, how to upgrade and modify your own car to offset the cost impact of rising oil prices is the key to saving money.
