No, I can't explain it. I'm not a game biologist or a nutritionist. I will tell you that it works.
We mostly use spin cast feeders.
However we do corn roads and sometimes will bait an area that does not have a feeder.
I was told about it several years back and have tried it several times when I'm baiting an area that doesn't have a feeder or a pig pipe, by pouring it in a pile or in a line. Deer and coons don't seem to like it and it can also be used in traps without the fear of attacting deer. It's not magic, and it helps to be in an area that has hogs.
Have also soaked burlap bags in burnt motor oil/diesel and tied around a tree with tie wire. Hogs like that to rub against. I guess it helps keep the fleas and ticks down.
Best,

Put some sulphur powder in that oil and it'll cure the mange and you'll have the best looking hogs around!!
