Many businesses handle used oil, including service stations, fleet maintenance facilities, and others. Learn more about used oil management requirements below.
Used oil is any oil that has been refined from crude or synthetic oil that has been used and as a result is contaminated by physical or chemical impurities (e.g., lubricants, electrical insulation oil, hydraulic fluid, heat transfer oil, brake fluid, refrigeration oil, grease, or machine cutting oil).
Used oil does not include used oil mixed with hazardous waste (except for specific instances), petroleum and synthetic based-products used as a solvent, antifreeze, wastewater from which the oil has been removed, or oil-contaminated media or debris.

Used Oil is considered on-specification if it does not exceed any of the following limits:
|Constituent / Property||Maximum Allowable Level (ppm)|
|Lead||100 ppm maximum|
Used oil regulations do not apply if used oil is determined to be on-specification. It can be stored, transported, and burned as fuel oil. Analytical and transport records should be maintained to justify this designation. Additional requirements for burning used oil containing polychlorinated biphenyls (PCBs) are found in 40 CFR 761.20(e).
Used oil filters can be recycled for their scrap metal value if the oil is removed. The filters are exempt from the used oil requirements when properly recycled or disposed of:
- Puncture the nonterne-plated filter, anti-drain back valve, or filter dome end.
- Crush or dismantle and hot drain the filter. Hot draining drains the oil filter at near engine-operating temperature and above room temperature (60°F) for at least 12 hours.
- Properly manage used oil collected from filters under the requirements above.
