Motor oil

Used motor oil contains toxic substances that can contaminate our land, ground water and ocean. The County of Hawai‘i operates a program for the do-it-yourself person who changes their own non-business vehicle’s motor oil. Please take it to one of the locations below.

Unfortunately, at this time, empty motor oil containers are not recyclable at a global level. Research is being conducted to study how to remove oil from plastic, but is still in development. To avoid contamination of other recyclable plastic, empty motor oil containers need to be placed in regular disposal.

Another suggestion (thanks to a local resident!) is to let your used oil filter sit and drain the oil from the filter. Up to a quart of oil can be sitting in your oil filter, so maximize your recycling by draining the oil filter of old oil as well!

Commercial, Farm or Business Generators

Commercial, farm or business generators of used motor oil shall contact the following Used Motor Oil Collection Companies:

Unitek Solvent Services 935-8180 (islandwide service)
Hawaii Petroleum 961-2661 (islandwide service)
AKW Environmental 430-2339

For more options please see the Permitted Used Oil Transporters/Processors list on the State of Hawai‘i Department of Health’s Hazardous Waste Section’s website.  Commercial businesses, farms or agencies are prohibited from using household only drop-off services.

There is a 10 gallon limit from household do-it-yourself generators only.  Do not use bleach, antifreeze or pesticide bottles to transport your used motor oil as this is hazardous and will contaminate the oil.
