Many drivers do not travel long distances from day to day, either on weekends, or on short holidays, and cannot reach 6,000 kilometres a year. A lot of people get into two extremes: some felt that the car was being driven and worn and that maintenance could be delayed, while others were being taken away by the 4s-recommended project, which had a very low mileage but had made a lot of unnecessary maintenance and was being used for nothing。
The core logic of car maintenance, with many remembering only “kilometres of maintenance”, ignores another important dimension — the time cycle. Such consumables as oil, rubber and fluids, even if the car is not parked, they can be naturally aging and oxidizing, but not as many kilometres as possible, and their performance remains the same. With less than 6,000 kilometres a year, which is typical of low usage rates, maintenance does not allow for the replicating of the 12,000-kilometer owner programme per year, taking into account both the mileage plus time criteria, and the resulting project cannot be saved and the redundant project has a rational trade-off. Here's the idea of a maintenance package。
I. Core: oil and machine filtering, priority time, not just km
The oil is a top priority for the maintenance of the engine and is also the most susceptible project for low mileage owners. The mainstream of domestic vehicles is now full synthetic oil, and the factory manual is generally marked 10,000 kilometres or one year, whichever is first. A lot of people have read this, but they don't really understand it。
Less than 6,000 kilometres a year and 10,000 kilometres a year, but one year later, oil and machine filters will be replaced. The simple reason for this is that oil is in the engine for long periods of time and oxidizes the air, while water, fuel dilutes in the warp axle boxes, slowly reduces the viscosity of the oil and the resistance to grinding additives. The vehicle is parked for long periods of time and the oil will flow back into the oil casings. The next start-up moment is when engine parts lack oil and lubricants and the wear and tear of dry friction is more visible than normal short-distance travel。
Here's the difference between a mistake: if it's not all synthetic oil, it'll last for two years. Unlike the original model plant, some of the old car-type manuals refer to the semi-annual replacement of mineral oil, which cannot be extended to one year even if it runs only 2,000 kilometres a year. Prior to maintenance, the first step would have to be to flip the original plant maintenance manual and benchmark it with the original plant marking, which is the most reliable basis for not listening to other people on the internet applying a single standard。
The filters and oils are compatible, each time the oils are replaced and the filters are replaced simultaneously. The internal filtering paper intercepts impurities, the long-term use of filter plugs, the reduced ability to filter and the non-replacement of oil alone are equal to half of white. Low-mile vehicles are not blindly selected for top-priced racing oils, and according to the original plant specifications, the choice of fully qualified synthetic oils from the formal channels is possible, with emphasis on timely replacement rather than pursuing higher-priced products。
There is also a tendency for oil losses to be triggered at short distances. If the engine goes out before normal working temperatures are reached, although the total mileage is less than 6,000 kilometres a year, most of which is a few kilometres short, the aging rate of the engine will be faster and it can be replaced a little earlier, without a year of death。
Air filtering cores, air-conditioning filtering cores: combined with environment, flexible replacement without mechanical fixed cycles
Air filter cores are responsible for filtering the air into the engine, air conditioning cores are internal wind filtering, and the two cores are vulnerable, and the low mileage owner does not strictly follow the replacement rhythm of the large mileage vehicle。
Air filtration cores, if normally paved roads, mainly in urban areas, are less dusty and less than 6,000 kilometres per year, are generally inspected annually and can be replaced every 1-2 years. The state is removed for each maintenance, and if the filter is blackened, suffocated with a large amount of sand, broken, it is replaced directly; if only surface ash, the air gun can be used to blow and clean from the inside and continue to be used. Note that air gun pressure cannot be too high, otherwise the filter fibres will be blown loose and filter accuracy will decline. The replacement cycle will be shortened if construction sites, dirt roads and large sand and dust segments are frequently used, even if the mileage is low。
Air-conditioning cores are related to the health of the vehicle and many car owners value it. Its replacement is mainly based on the use of scenery: in the wet and rain-fed areas of the south, which are prone to ailments, it is recommended to be replaced once a year, and in the dry areas of the north, which can be replaced by a year and a half check. As long as the air conditioner is spicy and the wind is significantly smaller, it must be replaced in a timely manner, regardless of how many kilometres it runs. Air-conditioning filter cores have ordinary unwieldy and activated carbon money, and activated carbon is better adsorbed with a slightly higher price and can be chosen on the basis of their own needs, without the need to impose high-end payments。
The two filter cores are low-cost fittings, but do not remain unchanged for long periods of time. Empty filter plugs cause gas insufficiency and engine fuel consumption increases; when the air conditioning core is molded, the opening of the air conditioner can smell and affect the driving experience。
Iii. Brake system maintenance:Brake oilChange on time. Brake blades are based on actual wear and tear
The brake system relates to the safety of the vehicle, and the single most vulnerable vehicle is the brake oil. The brake oil is humid, and this is its own physical characteristic, even if the car is barely open, and the brake oil is exposed to the water in the air for a long period of time and the water content is slowly increasing. After the water content has been exceeded, brake oil boiling points have declined, and continuous brakes are prone to air resistance, resulting in softening of brake pedals and reduced brake performance。
The vast majority of home-based plants require a two-year or 40,000-kilometre replacement of brake oil, whichever comes first. In less than 6,000 kilometres a year, and in two years the total mileage is roughly more than 10,000 kilometres, and the number of kilometres is far from 40,000 kilometres, but in two years the brake oil needs to be replaced. This project cannot be saved, and many low-mile drivers think the brakes are not working, and the brake oil is never changed. At the time of replacement, it is possible to allow the repair shop to measure the amount of water first with brake oil and, if more than 3 per cent of the amount is already available, it is recommended to replace it; if the value is low, it may also be delayed, as appropriate, in conjunction with the manual, but not for more than three years。
The brake blades are different, being a friction consumption, and their lifetime and actual frequency, driving habits are strongly related. In less than 6,000 kilometres a year, brakes are rarely used, and brake blades are generally thick enough to be replaced in time. On each occasion of maintenance, the vehicle was lifted to check the remaining thickness of the brake blades, as well as to check whether the brake plate had been raised and polished. The general remaining thickness is less than 3 mm and replacement is scheduled. The long-term parking of vehicles at a low mileage is particularly recommended for the project, as long-term non-movement makes the conductor vulnerable to rusty card stagnation and subsequent grinding and brake drag。
There is also a handbrake (electronic handbrake), which is regularly checked for vehicles with low mileage, and the electrical handbrake electrics, pull wires, and long-term static, which can be activated several times at regular intervals to maintain institutional activity。
IvTyres: stopping the risk of ageing, greater than wear and tear, with emphasis on the examination of crack drum packs
Tyres are rubber products and ageing is measured over time, not just kilometres. Many thought that tyres could be used at all times with fewer tyres, but that tyre rubber would be hardened over time, there would be tiny cracks, commonly referred to as to to to turtle cracks, with reduced gripping power after ageing, and high-speed explosive。
For domestic vehicle tyres, the general industry reference standard, recommended for replacement for up to 10 years from the date of production, is suitable for low mileage vehicles. Even if it runs thousands of kilometres a year and the tires are deep, replacement is recommended as long as the tires are more than six years old and there are large numbers of tortoise fractures on the side。
The main features of the normal maintenance check are: first, to see if there are any cracks, drums and nails on the side, and on the side; second, to examine the tire pressure, which is slowly and naturally depressed by long-term car tires, and to recommend that the tire pressure be checked once a month, not to be too high or too low, in accordance with the standard signposts of the b column of the door; third, if the long-term stop does not move for weeks in a row, the tyre is partially under pressure, it will be flat, it will shake at low speeds after re-entry, with a low mileage not to be completely unmoved for as many months as possible, with a short break every one or two weeks to allow the tyre to move and avoid local long-term pressure distortion。
At the same time, tyre balance, four-wheel positioning, and low-mile vehicles are not subject to regular enforcement. Only when there is a high-speed steering wheel vibrating, running and tire grinding are these things done, and when no maintenance is required, they are recommended for compulsory project。
V. Freedom reduction resources, freedom freedom equipment: don't bulletly early returned in exchange
Vector tank oil and anti-frozen fluid are items that are often marketed by low-mile drivers and must be rational here。
For transformer tank oil, be it at, cvt or double-departure transformer, the original plant manual has a clear replacement cycle, usually 60,000 to 80,000 km, or six years, whichever comes first. With less than 6,000 kilometres per year and a total mileage of 60,000 kilometres over many years, priority is given to time. If the time is up, even if the mileage is very low, the transformer oil will be replaced; if the time is not, no advance replacement will be required. The transformer tank oil has been static for a long time and, although slowly ageing, it is ageing at a much slower rate than motor oil and brake oil, with early replacement being a surplus consumption. When replaced, preference was given to the original plant specification transformer tank oil and it was not recommended to replace the different specifications at random。
Refrigerated fluids (cooled fluids) with the effect of dissipation of engines, anti-frozen and preservative. The main long-lasting anti-frozen fluid is generally marked as replacement for 5 years or 100,000 km, whichever is first. Low mileage vehicles, which are difficult to meet, are replaced by five years of time. For each maintenance, it is possible to check the level of anti-frozen fluids to see if there is any fuzzy, rusty or, in case of early deterioration, early replacement. At the same time, it is possible to detect ice points, which in the north meet standards by winter. Note that composting of anti-freeze fluids of different colours is not recommended and may result in deposition and erosion of waterways。
Vi. Other asylum and components: ablamming bella, those / abuse transports, pypose
1. Batteries
Low-mile vehicles, electric cylinders are high-facing points. The vehicle is permanently shut down, the battery is continuously self-recharged, and the generator is insufficiently charged if it is often travelling short distances, the battery is easily lost and its life is reduced. The normal lead-acid batteries have a normal lifetime of 3-5 years and long-term parked cars, which may be reduced to more than 2 years。
In maintenance, it is recommended that the vessel's health be measured and voltage activated annually. Day-to-day use, timely detection is required in the event of a failed, medium-controlled electrical alarm. For long-term vehicles, it is proposed to start running for more than 20 minutes every two weeks to recharge the bottle, with the condition that it can be maintained with an intelligent charger。
Annex the belt
This is the external movement belt of the engine, which drives generators, pumps, air conditioning compressors. Rubber material, which breaks with age over time, usually has a six-year original plant cycle, and low-mile vehicles, although worn, continue to grow. During maintenance, the hood was opened to check for cracks, loss of teeth, laxity and, in the case of cracks, timely replacement to avoid interruptions, resulting in breakdown of air conditioners, non-power generation of generators, suspension of pumps and high temperature of engines。
This is a high-risk project, which is strictly in accordance with the manual cycle, and cannot be delayed indefinitely because of the low mileage; most new vehicles are now in a straight-time chain and normal conditions are not maintained, and it is sufficient to check regularly for any noises。
3. Spark plugs
The spark plugs are consumables, with most of the original plant cycles ranging from 40,000 to 60,000 kilometres. With less than 6,000 kilometres a year, the total mileage was slow to reach, and vehicles with low mileage were replaced without time. Each maintenance can be broken to observe electrodes burning, carbon accumulation and replacement if there is a failure of ignition, a glitch, and fuel consumption increases. If everything is normal, it will be sufficient to wait until the mileage cycle is close to the original plant, without the need for early replacement。
Vii. Low mileage vehicles, projects that can be suspended and rationally refused excessive maintenance
A number of maintenance stores, faced with low-mile drivers, fuel system cleaning, carbon sequestration in gas routes, speedbox deep cycle cleaning, chassis armour, circuit protection agents, etc., are recommended. It should be understood that carbon sequestration is a product of long-term fuel combustion, frequent short distances, with a low total mileage per year and a very slow rate of carbon accumulation, and that no regular clean-up type conservation is required without the failure of glideing, acceleration and a marked increase in fuel consumption。
Only the corresponding symptoms of failure were verified as carbon-induced and re-targeted. Clean-up projects are not considered mandatory maintenance, and they are generally expensive, with low returns and excessive maintenance for vehicles with low mileage and good performance。
At the same time, such things as chassis protection and car polishing are value-added maintenance, not mandatory maintenance projects, determined by the vehicle parking environment, personal needs and not mandatory annually。
Viii. Day-to-day maintenance habits for low-mile vehicles, extending the life of the vehicle
Maintenance is not just a change of plant, but routine car usage is equally important。
First, long-term stoppages of more than a month, prolonged static, oil seals, rubber pieces that can easily be hardened, electric bottles that are out of power, and tyres that are pressured to transform。
Second, short-distance travel, as much as possible to keep engines at normal water temperatures, and frequent cold start-up short distances are important incentives for engine wear, carbon accumulation and oil aging。
Thirdly, the use of dry ventilated garages to minimize the erosion of rain and the aging of rubber units by the tide。
Fourth, maintenance records are maintained for each maintenance, replacement items, time, mileage are registered, and the next maintenance is based on double standards of time and mileage, without missing the cycle。
Fifthly, all consumables should be given preference over the regular channel, with spare parts of higher quality than frequent replacements, and poor quality oil, brake oil, if replaced on time, can damage the machinery。
Ix. Summary
Low mileage vehicles, which run less than 6,000 kilometres a year, maintain the core sentence: mileage is a reference, time is the bottom line, safety-related consumables are replaced on time, wear and tear items are considered physical, and unwarranted over-maintenance is rejected。
The oil filter is replaced with the original plant's time cycle; brake oil is prioritized with a two-year cycle; tyres, bottles, attachment belts focus on ageing; long-cycle items such as gear tank oil, anti-freezing fluid, spark plugs, which is based on the original plant manual time + mileage; empty filter air-conditioning cores are replaced with environmental checks; cleaning items are not performed without failure。
Adherence to the scheme would neither lead to safety risks due to prolonged parking, neglect of ageing components, nor to blind consumption, save unnecessary maintenance costs, and allow low-use domestic vehicles to remain stable and reliable in the long term。
