I'd guess the included cable is a 7-19 which means it has 7 strands of 19 wires in the cables construction. You may find that a 7-7 cable will allow for the thicker liquid to be wicked better as the voids within the cable are larger.

You'll want non-coated stainless steel cable and clean it extensively. Wrapping the cable with stainless mesh can help as mentioned.
