commercial's not a problem, you spray it before you load it, you don't spray it and leave it sitting around. for home use, as long as it's covered it's not going to leach anything and more importantly, it won't be sprayed with so much oil that it should leach anything substantial anyway. I like a 0w20 motor oil. or a used motor oil, but it's a little thicker; probably about 1/2 gallon/ton, mabey less.
