I've got some 0W-30 VW/Audi 504.00/507.00 oil for sale. 6/1 qt in a box and I have 5 boxes. These are brand new and unopened. I sold the car I used it in. 

This goes for $20-30 a qt in Amazon, much more from the stealership. 

Cash or trade for 9mm 147gr or higher/subsonic. Or 556 62gr or higher. Or guns. Let me know what you have that is interesting.
