I've never heard of anyone using oil in their can. But, what one guy was using was a Sam's sized bottle of hand sanitizer. It's a gell, and since it's mostly just water and alcohol, it evaporates nicely leaving little or no residue. They guy swore buy this stuff.
Two things. First, not all cans are made to be shot wet. You don't want to go gunking up a can that was made to be a dry can. Second, whatever "stuff" you use in your can needs to have a high rate of evaporation - that's what absorbs and converts some of the sound energy.
