It is very important to recycle used motor oil & filters. One quart of improperly disposed oil can pollute over 250,000 gallons of drinking water. Oil poured into the ground can seep into the groundwater table and contaminate drinking water supplies. It is strongly recommended to call before attempting to drop-off motor oil.

Did you know that State-certified used oil collection centers will take your used motor oil 
and will even pay you 40 a gallon? 

By law, transportation of motor oil cannot exceed 5 gallons per container with a maximum of 15 gallons per trip (three 5 gallon containers). 
Most drop-off facilities won't accept more than 5 gallons per visit. 
Do not mix motor oil with other automotive fluids.
