The best way to get rid of oil is by recycling it. This saves valuable resources. Oil doesn’t wear out, it just needs to be clean using professional tools to be ready for use again. In fact, according to the EPA, to produce around 2.5 quarts of lubricating oil, you need one gallon of used oil or as much as 42 gallons of crude oil. So for the environment, it really makes sense to recycle the oil.
After you’ve drained your oil into an oil catch can, pour it into an empty, clean bottle, then bring it to a recycling center. Most local car mechanic shops and recycling centers will accept it. If you don’t have one that’s nearby, then you can try a Jiffy Lube or similar. If you are really struggling, you can check with your large local supermarket as some will accept used oil.
If you are still struggling, contain your local dump to check if they will accept used oil as many do. However, this is the least eco-friendly as a lot of the oil will just end up in the soil and local bodies of water, which will cause serious harm to the local wildlife in your area.
