It works, but tap oil designed by engineers for the material you are working with is going to work better.
But can you eat the tap oil?? Lmao Crisco supposed to be if you don't got that fancy oil.
I wouldn't eat Crisco either. I think they have changed formulas to something that might be better, but last I checked 20 years ago it was full of harmful trans-fats.
Agreed, I've tapped some nasty materials - 1 tap per hole nasty - and the fluid change gave me the more than 8 holes for the same new tap.
That really opened my eyes to engineered fluids.
