Hmmmm...I am thinking not a good idea....

A&P Mechanic here, and I can tell you that anything and everything goes into those drums...I don't care what they tell you.

Sure, I would sump 10 727's a night and have gallons of good fuel, it would go into the sump barrel....then I would do a 1000 hour on a APU and all that oil would go into the sump barrel along with safety wire and anything else that made it to the 5 gallon bucket I was using.

No way in hell I would use sumped fuel on my jet, the 15 bucks for 5 gallons is well worth it when it comes to my equipment.

YMMV
