If you have empty plastic motor oil containers, you may think that they are easily recyclable because they are marked as a No. 2 plastic. But the reality is that the residual coating from the oil can contaminate a whole load of recyclables. These containers are often unaccepted by recycling haulers, so it's best to avoid putting them into your recycling bin. Instead, take them to a service station that performs oil changes. They have the infrastructure in place to properly dispose of old oil and recycle empty oil containers.
