The Burt Company was the first chip maker to oil chips. I think they started in the 1960's. This is the method used by the Burt Company: fill an empty Coke bottle with 10-30 motor oil and apply the motor oil to a rag; grab a stack of chips (15 or 20) in the left hand and with an oil rag in your right hand apply a liberal amount of oil to the edge of all the chips in the stack; rotate the stack to insure complete coverage; wipe off any excess oil with a clean rag. THE FACTORY NEVER OILED ANY OTHER PART OF THE CHIP. This is the sole factory authorized method of oiling chips.

ASM has replaced motor oil with mineral oil which gives a cleaner finish.
