yep, i'll have to agree with johnr
when it comes to oily floors they don't make a non-slip tire
as he said when you mix water and oil together on a tire there's not much you can do about it except pucker up and hope you don't wipe anything out if you start sliding.
Now if you want a more positive traction point you might want to consider doing some work to the floor instead, making it rougher, having traction ridges cut into it or something along those lines.
