Used Oil Filters

Used oil filters must be thoroughly hot-drained of all oil prior to disposal. Hot-draining generally means draining oil close to or at engine temperature. Oil filters must be gravity hotdrained by one of the following methods:

1. Puncture the filter anti-drainback valve or the filter dome end and hot drain for 12-24 hours;
2. Hot drain and crush; or
3. Dismantle and hot-drain.

Filters that have been gravity hot-drained by one of these methods can then be placed in the trash.

Correct:

• Hot-drain, crush, split, and/or process oil filters by other means to remove the oil from the filter.
• Keep processed filters in a separate container labeled “Used Oil Filters.”
• Put oil drained from filters into your used oil container.

Incorrect:

• Do Not put undrained filters into the trash.
• Do Not put terne plated (an alloy of tin and lead) oil filters in the dumpster. They are considered hazardous waste due to the lead content.
