So do, some don't, so would, and some won't!
I do and I like it! I didi a research because at Tandy, there pure is $14.99 a quart, I just bought a quart at a Attwood store for $6.89 a quart and it is 100% pure.
If you do not have a Attwood store then do a search for Horse Health Products a div. of Farnam Co. inc, and see if you can find a local dealer! That is a lot of saving.
If this only helps one person, it was worth posting!
Have a good Day
