Really? You lucky bastard! Round here they are paying a buck forty a gallon for damn wmo! All my sources wanna charge me now. 
That seems fair to me. What, with crude oil being $100+ for a 55 gallon barrel, I resent giving used oil away for free to the store where I bought it.
Some of the crude oil, the way it comes out of the ground, is pretty nasty too, depending on the grade.
barrels of crude are 42 gallons last time i checked...
So 55 is like a bonus barrel? New Improved Family size. More for more money.
