The proper method of disposing used engine oil and filters is as follows:
Drain the Oil Properly: Ensure the oil is drained into a sealed container to avoid spills.
Dispose of Oil in Designated Recycling Centers: Used engine oil should be taken to recycling centers or disposal facilities equipped to handle hazardous waste.
Recycle the Oil Filter: Oil filters should be drained for 24 hours to remove excess oil, then disposed of according to local regulations. They may be recycled if appropriate.
Avoid Disposal in Landfills: Never dispose of engine oil or filters in the trash, as they contain harmful contaminants that can pollute the environment.
