Hello, i'm lin mau。
Most of the cars are expensive, not because they have a high failure rate, but because they're used to itOvermaintenanceI don't know. 4s stores and repair shops often recommend high-priced projects on the grounds of “engine protection, elimination of hazards, longer life”, and many unsure car owners are paid only to pay, and the cost of raising cars is tens of millions of dollars a year。
In fact, car maintenance is not that complicated, and the standard cycles are indicated. Today, we share the gold skills of 10 lifetime cars, which have been summed up by old drivers and auto-skillers, avoiding 90 per cent of maintenance packages, driving a car for 10 years and saving millions of dollars。
1. EverythingMaintenance manualI'm not listening to oral sales
This is the core, the cost-saving part of all techniques. The maintenance manual for each vehicle is the only official standard established by the plant after tens of thousands of tests, indicating the replacement period for all fluids, spare parts and no alternatives。
The “early maintenance, upgrading projects, deep maintenance” recommended by the repair shop are all profit packages. Remember one principle: items that are not written in the manual, no matter how scary the sales may be, do not do it; the cycle indicated in the manual is that no car will be in trouble until the mileage is changed。
Two, you don't have to change the oil
The biggest lie is the fact that many door shops have to change the car's owner's oil for 5,000 kilometres, or else hurt the engine。
The standard replacement period is now 10,000 km or 1 year, whichever is earlier. Only old mineral oils require 5,000 kilometres of replacement。
It is totally unnecessary to change oil in advance blindly, at two or three times a year. The engine remains stable as long as 10,000 kilometres of regular fully synthesized oil are replaced。
Three or two filter cores can save money, empty filters can blow, air conditioning can switch
The oil filter core has to be replaced simultaneously every time it is needed and cannot be saved. However, air filters and air-conditioning filters need not be changed frequently:
Air filter cores of 15,000 - 20,000 km are replaced, and normally they can continue to be used without each maintenance being replaced by a simple air rifle
The air-conditioning cores are replaced by approximately 10,000 kilometres, and online fittings can be replaced in three minutes with only $230, without a hundred dollars at the door, at a direct price。
4. Carbon washing, engine hoisting bottles, pure iq tax
New vehicles, semi-new vehicles up to 50,000 kilometres, do not need to clean carbon, oil roads or inside engines at all。
Hundreds of gallon bottles and deep carbon washing at the door are not only useless, but also poorly operated, they corrupt engine parts and block three dollars. Daily small carbon accumulation, with regular high speed and regular fuel, allows for self-cleaning without any cost. Targeted clean-up will be considered only if the vehicle is twitched and the power is significantly reduced。
5. Vector tank oil, sorted and replaced, recyclable
Many door-to-door shops are running around 20,000 kilometres of fuel in transformer tanks, and there is a wide gap in the cycles of different transformers: 80 to 100,000 kilometres for at transformers, 4 to 6,000 kilometres for cvt transformers and 60,000 to 80,000 kilometres for wet doubles。
The replacement method is only gravitational exchange, with high value and no damage to speedboxes. Recyclers need to use double the amount of oil at twice the price and are also vulnerable to shocks to transformer valves。
6. Brake oil, anti-frozen fluid, replacement on a periodic basis, no advance
Brake oils of 2 years or 40,000 kilometres, anti-freeze fluids of 4 years or 60,000 kilometres, both of which are just in need of maintenance and must be replaced when they are due, and do not fall due without pipe。
The door shop often said that “the fluids were decomposed and exposed to safety risks” and that early replacement of the car owner was in order to earn working hours. Regular plant fluids are fully viable through the official cycle, and early replacement is a waste of money。
Seven, spark plugs, brakes, no time
The spark plugs and brake blades do not have a fixed replacement death standard, except for actual wear and tear:
The spark plugs, if they are lit, and they are not shaky, will not be replaced
The remaining length of the brakes is greater than 3 mm, and the brakes are sound and soft and need not be replaced。
Many of the shops have seen the age of the car changing, with a set of brakes and sparks pouring out hundreds of pieces, which are simply harvesters。
8. Rejection of oil additives, engine protection agents
All oil additives and engine protections are chicken ribs, at several dozen or several hundred prices。
The formal oil itself contains resistant, clean and oxidizing components, and the formulation is sufficiently developed. The addition of products is not only not protective, but may also disrupt the balance of motor oil, affect engine performance and pay purely iq taxes。
Nine. First order to 4s
For the first time, the new vehicle was free of charge and had to go to shop 4s to keep maintenance records and to guarantee its integrity。
After the bail, there was no need to keep 4s. Formal maintenance chains, auto repair shops, fittings, and working hours are less expensive, and the same maintenance projects save half of the cost without any impact on quality assurance。
10, low-cost lead maintenance, covert loops
The 99-dollar and 199-dollar complete maintenance package on the market is mostly a diversion trap. After a low price to the store, the door store will sell the cleaning, replacement and upgrading of the oil, at a level far exceeding the normal maintenance costs。
The maintenance must be preceded by written quotations indicating the project, accessories, hours worked, refusal of oral quotations, hidden consumption, and no temporary additions。
My friend zhang, who used to be a well-established “maintenance white”, drove to 4s every time in the past few years and sold all the recommended items. Three or four times a year, at a cost of hundreds of thousands at a time, and close to $20,000 a year。
Most ridiculously, his new vehicle, 20,000 kilometres away, was tricked into engine cleaning, oil road maintenance, and spent almost $1,000, after which his friends had told him that the new car did not need any of these items and was simply trapped。
He then ate the maintenance manual, bearing in mind the 10 techniques, did only for immediate needs and refused all excessive maintenance. The same vehicle, the same mileage, was reduced to a direct cost of maintenance of 34,000 a year, the vehicle had been in operation for eight years, and the engine and gearbox remained in good condition and without any malfunction。
A small confession: the biggest cost of car maintenance is never the loss of the car itself, but the constant maintenance of the vehicle。
Finally, a summary of the core car-keeping logic: maintenance is done only on a first-demand basis as per the manual, without excess maintenance, without belief in oral sales and without undue expense. The durability of the car depends on standard maintenance, not on frequent spending。
