I just had one of our family cars’ engine oil replaced as a periodic maintenance to keep our vehicles in tip-top shape. Considering we have three (3) vehicles at our home and each year we amount to 3-4 times of oil change for each car with almost 4 gallons of oil removed each time. Imagine that we are dumping 16 gallons of used oil for each car.
Used oil is toxic for the environment. Dumping used oil in our garbage bins or in the soil does not reduce the negative effects of sustaining even plant life as they may seep into our water tables.
I believe most of us who do our own oil change would end up stacking large cans of these used oils in our garages or even just leaving them lying around our backyard – waiting for them to be reused for any possible household application which more often than not, will not be done.
It is good to know that used engine oil can be recycled by re-refining it, reconditioning or re-processing.
Re-refining used engine oil is now possible provided that a proper and modern way of processing can treat used motor oils for them to be used as a base stock to create “new” engine oil. However, the demand for these products is currently not that significant in the market, making it hard for manufacturers to consider undertaking the process.
Used oil can also be reconditioned or cleaned by removing insoluble impurities present so the oil can be used again and again, yet the cleaning process will not likely restore the original quality of the oil. However, it can still aid in lubricating tasks using additives thus extending the oil’s life and purpose.
Used oil is one of the industrial wastes that we have to consider since majority of the population is using cars in their daily activities. I hope we can find a way to lessen the dumping of used motor oils so we can sustain life even with the presence of our cool rides.
