You can drain the used oil both yourself and at a service station. By unscrewing the drain plug, the oil must be drained into a sealed container. The drained oil must be disposed of as its release into the environment is prohibited for environmental reasons. Waste oil can be reused as fuel or hydraulic fluid.
The trouble-free operation of an automobile engine requires periodic oil changes. To change the engine oil, you first need to drain the used oil from it. You can drain the old oil both at a service station and on your own if the car owner has a garage with a viewing hole and basic knowledge of the design of his own car.
Before draining the oil, you must warm up the engine - let it idle for a while, or take a short trip. The heated oil becomes less viscous and better flows out of the working cavities of the engine. To drain the oil, you will need a container, which can be a plastic canister with a tight-fitting lid.
Oil draining
First of all, it is necessary to place the car above the inspection pit. If not, you can raise the front of the vehicle using jacks. To avoid an accident, the wheels of the vehicle must be secured.
To drain the oil, unscrew the drain plug with a wrench. In order not to get your hands dirty and not burn yourself on the heated crankcase of the engine, work must be done with gloves. When unscrewing, the plug must be held so that it does not fall into the container with the drained oil.
After the oil is drained into the canister, you can unscrew the oil filter and replace it with a new one. A small amount of new oil must be poured into the filter before refitting to prevent air lock.
Disposal of drained oil
The drained oil must not be thrown into the trash, or even more so, poured onto the ground. For environmental reasons, used oil must be disposed of properly. A number of companies specialize in the disposal of used oil, which either use it commercially or store it in environmentally friendly conditions in dedicated warehouses.
Some recycling companies pay car owners a certain amount for each liter of used oil transferred. If there is no competition among similar companies in the city, the drained oil is accepted free of charge.
Waste oil can be cleaned and used as engine oil for engines of agricultural machinery, or as one of the components of the hydraulic fluid for the drive of lifting mechanisms. It is also widely used as a fuel for heating boilers.
