That sounds about right, depending on where you are at. When I had my used car business disaster, one of the local full service oil companies would charge about $75 to pick up a bbl of old oil, and drop me a clean bbl. That was about five or six years ago.
Used oil is the bargain spot of hazardous waste disposal because it can be recycled or burned as a fuel. There is no excuse for not disposing of it in a safe, legal, manner. I would think Jiffy Lube could generate a large enough waste stream to get somebody reputable to remove it for free, unless they were careless and let it get adulterated with some other fluid / waste.
The last large real estate project I did, I had to legally dispose of about 35-40 bbls of old industrial precursors and solvents. Safety Kleen charged an average of about $800/bbl to remove and incinerate that stuff, IIRC. A lot of the drums had never even been opened, and the contents were likely as good as the day they were made, but off to the incinerator they went.
