Cars and trucks

Nonprofit groups including Goodwill Industries and Habitat for Humanity accept vehicles; many don't care whether they run or not. Because of stricter tax rules in recent years, you shouldn't expect a whopping deduction. To donate a vehicle, first check whether an organization is a charity that can receive tax-deductible contributions by perusing IRS Publication 78, an annual list of most charities, at www.irs.gov/eo. Look under "Search for Charities." (Some nonprofits such as churches are not listed.) "A Donor's Guide to Car Donations," a free download at www.irs.gov/pub/irs-tege/pub4303.pdf, notes what paperwork you'll need to claim a tax deduction.

Motor oil and gas

Never dump used motor oil on the ground, in the trash, or into drains or storm sewers. Pour used oil into a clean container with a secure lid and label; don't use containers that once held bleach or other chemicals. Walmart lube centers and some service stations accept used oil. You'll also find local recyclers at www.earth911.com.

Store unwanted gasoline in a childproof metal or plastic container approved by Underwriters Laboratory or another independent testing lab. Label the container. Then contact your hazardous-waste-collection center. To reduce the need for disposal, consider using a gasoline stabilizer, which keeps gas usable for a year or more.
