I'm the wise acre that half fills a Visine squeeze bottle with cod liver oil ~ best not to leave it in the medicine area.
Most of it goes on lures and bait of any kind.
Squirt yer split-shot and swivels too, as more scent is good.
If you need stinkier bait, just add a tiny pinch of yeast and keep it warm for a few days. You'll know when it's
ready.
