To tell you the truth, i have been driving with my driver's license for 10 years, with two of my family's scooter cars, one of which commutes from work to work every day, full of miles per month, and the other, who spends years eating ash in a vault, running two or three thousand kilometres to the top of his head, mostly locked up。
I was very real in the last few years when i bought a car. One bite of 5,000 kilometres or six months, whichever comes first, has to be replaced with oil, three filters, with no delay. The idle car was only 2,000 miles away, and i drove to the shop on time for half a year, $3,400 a day, twice a year, spent nothing, and now i'm thinking it's all for nothing。
Then he got acquainted with the teacher who had been in a car shop for more than a decade, and he went straight through the industry: car maintenance was never the rule of 5,000 kilometres in half a year, and all parts were subject to a distance, double time limit, first. The vehicles have been parked for long periods of time and cannot run thousands of kilometres a year, and there is no need for frequent replacement of fluid spare parts, with the vast majority of early maintenance being purely a profit-making arrangement at the door。
Many of the drivers are trapped in a single trick: if they don't drive, it's bad for the oil. This sentence is only half true and half misleading. Today, the business is sold, the word is broken down, the cars are driven infrequently, the maintenance is delayed and the projects must be replaced by the years。
I. Oil + machine filtering: no six months of mandatory replacement at low mileage
Maintenance is expensive as oil, and it is one of the most powerful sales items。
4s store uniform calibre: mineral oil must be replaced for six months and all synthetic oil must be replaced for one year。
But if your car is less than 3,000 kilometres a year, parked in a dry garage for a long time, and is rarely activated coldly, the official whole-synthetic oil will not oxidize for 18 months。
The core of oil deterioration is not simply a stop, but rather an intrusion of water gas: every drive of just one or two kilometres, the engine temperature goes off before it rises, and the water in the gasoline flows back into the tank, accelerating the emulsion of the fluid. The engine's useful life can be lengthened as long as it runs out of space every week for half an hour and completely heats up the steam。
To provide a practical example: the manufacturer has marked 10,000 km/12 months of oil for the entire synthesis machine, whichever comes first. Only 2,000 kilometres a year, waiting until the end of the 12 months to replace them is completely secure, and there is no need for six months to force them into the shop; if less than 1,000 kilometres a year, up to 18 months of replacement, there is no damage to the engine. The filters are replaced with the oils, which need not be replaced alone。
Ii. Empty filtering, air-conditioning filtering: no time change for environmental losses
Air-filtration cores and air-conditioning cores are only used for road conditions and parking environments and have little to do with parking times。
In general, they travel only in clean urban areas, with few construction sites, dirt roads, few leaves, 2,000 kilometres of vehicles a year, empty filters and air guns, and enough for two years
Air-conditioning cores are the same, the parking environment is clean, there are no trees, no piles of oil and smoke, clean up once a year, and two years in exchange is sufficient。
Every time a door shop is maintained, it changes the filter core, each of which is hundreds of times less frequently replaced, and it is purely redundant。
Iii. Focus red! Brake oil, anti-frozen fluid, no delay
It is important to remember here that not all projects can be delayed, but both relate to the safety of the vehicle as a whole, even if the vehicle remains intact for a year, and must be replaced by a period of time, which cannot be saved。
The brake oil absorbs the water in the air on a continuous basis, softening the force of the brakes beyond the water mark, increasing the brake distance, making high-speed brakes highly vulnerable, with a standard replacement cycle of two years or 40,000 kilometres, with priority given to time
The permanent static of the anti-freezing fluids can corrosive water tanks, pipes and leaks of rust, which, regardless of the mileage, must be replaced in full for a period of four years, depending on the number of kilometres。
Iv. Flamps, transformer tank oil: all low mileage is replaced by miles
Firecrackers generally recommend 40,000 kilometres of replacement, with idle vehicles 2,000 kilometres per year, which are not available for several years and do not need to be replaced in advance
Most of the fuel replacement cycles for automatic transformer tanks are 60,000-80,000 kilometres, leaving the tanks completely unattended for three or four years as long as normal static conditions are virtually non-depleted. The fuel from the early switcher tanks is running at thousands of dollars, and it is pure and unnecessary。
V. Tyres, cylinders: stopping and losing is much greater than driving, and regular inspections cannot be lazy
A lot of drivers think they can't drive and tire bottles won't break
(b) long-term static pressure of tyres and natural ageing of rubber, even if it opens only a few hundred kilometres a year, the tyre must be carefully examined for a five-year period and forced to change for a six-year period
The vehicle will experience a slow loss of electricity during the static period, with long holds on for more than a month, and it is recommended that the negatives of the bottle be cut; the daily launch of the vehicle for 10 minutes per week to avoid the direct loss of cables, both of which are time-consuming and unrelated to the mileage。
Dismantling the underworld of the door shop's crazy maintenance
There's a lot of doubt. Why do you have to keep it on schedule when you know how little the car drives? Two core reasons:
1. Maintenance and repair is the core source of profits for the store, which is highly profitable for oil, filtration and maintenance products, and which are often not collected at the store
2. During the new quality insurance period, the manufacturer requires complete maintenance records in accordance with the manual standards to avoid late-stage mass pre-pumping; after the vehicle has been insured, the cycle can be adjusted in a flexible manner in accordance with its own mileage and without being bound by rules。
Clear demarcation recommendations:
1. During the new quality insurance period: to be carried out in strict compliance with the vehicle maintenance manual, to ensure that maintenance records are complete and to prevent the failure of the plant from denying the insurance
Vehicle insurance, with a distance of <5,000 kilometres per year: 12 months for oil replacement, 2 years for empty filtering, air-conditioning filtration, 4 years for brake oil, anti-freezing fluids, and only mileage for spark plugs, speed tank oils。
The core of vehicle maintenance is on-demand maintenance and not mechanical rigid adherence to fixed cycles。
Short-distance vehicles do oxidize faster than long-distance vehicles, but they are far from exaggerating as the “six months of engine failure” promoted by the door shop. Over-maintenance will only empty wallets in vain; however, they cannot be extremely inverted, and safety accessories such as brakes, cooling systems must be replaced over the years。
Not only would the engine and gearbox not be damaged by a reasonable rebalancing of the maintenance cycle, but a young man could save hundreds of car support money for refuelling and spare parts for the car
