Driving friends all know, Japan is generally necessary to maintain a car 5000 km, the US Department of Ashkenazi will be 10,000 km maintenance once a year, so a car is necessary to maintain an average 3-4 times, or even more.

Each time maintenance of waste oil must be replaced about 4L, 4S shop one day and a lot of maintenance amount, about 10-20 cars, then the country will produce many tons of waste oil is simply unimaginable a year. Although waste oil is of no use to us, but I am very curious 4s shop is usually how to deal with these costs of oil it?

We all know that there will be oil pollution, so 4s shop should not put the oil directly down the drain or casually throw. Not to mention the waste oil can make money and now specializes in the recovery of the oil market, oil costs about 2-3 dollars a pound less likely it is easily disposed of.

It is understood that the processing cost of oil generally three ways: 1, certified by the environmental protection department of formal institutions recycling 2, some small service points in remote points directly poured into the waste water ditch, 3, sold irregular recovery mechanism

General barrel of waste oil recovery mechanism can be sold in the formal 500-600 yuan, if not the formal institutions to sell 700-800, the middle there is the $ 200 price difference. For 4s shops have large output of waste oil which is also a substantial amount of income.

In addition, if a formal recovery mechanism also signed the transfer contract, subject to 1.2-1.8 million contract fee, so that the threshold has improved, the industry interpretation of this fee is charged back to less oil profits, but also pay waste oil barrel.

Therefore, the vast majority of 4S stores will choose a way to finally recover, recycle used oil then these institutions are doing with it? Take a look.

If the waste oil is recovered normal recovery mechanism will be used to produce building materials separator, made of waterproof material or diesel, will be performed without formal institutions processing used to make most of the counterfeit products, additives added after refining after the waste oil can be turned into new oil shiny, it looked exactly like it does not distinguish between true and false.

Hazardous waste oil can be caused by vehicles

Waste oil contains a variety of magazines, cleaning function is weak, the car will result in added maintenance period becomes shorter, poor engine performance, easy to produce coke, may lead to serious blew.

Theoretically 4S shops in big cities is not sold to the black heart of the waste oil recovery mechanism, but the auto repair shop and the city not allowed to say. So we go to a regular maintenance 4S shop maintenance or time to go buy oil at regular electricity supplier.
