I have not experienced this problem. I've been remulling my sand after every shakeout so perhaps this is why I don't have the problem. I do know however, there's at least 3 foundrys that I know of that use straight weight non detergent oil without problems. I buy my oil from Fleet & Farm, it's about as generic as you can get. I use 92% (strongest I can get) isopropyl alchihol as a catylist.
