I would not recommend using cooking oil in a cantenna-style dummy  
load. The problem is that cooking oil is hydroscopic. It will absorb  
water and allow the electronic components to corrode.

Mineral oil is an excellent choice. Transformer oil will work better,  
but it's harder to obtain and older versions contained potentially  
toxic PCBs. Mineral oil is inexpensive, and it will last for decades.
