I wouldn't be surprised that this ball did not handle much carrydown, if any at all. Low flare potential and high gloss factory polish combine to clear most heads easily and hit hard on the backend on CLEAN backends.
Being a PK 18 pearl, it can be scuffed or sanded for a smoother reaction that will handle more oil and more carrydown, but it will lose some of that backend - the usual story. I'd start with either a hand rubbing with a green nylon pad or a total sanding to 4000 grit matte finish (2000 grit if 4000 grit is too smooth).
I'd be inclined to keep it polished for when it can be used; it was a very good ball for most people on medium-light oil to as much as medium back when it was new. Now, it is mostly for light to medium-light, for the average bowler.
