The thing you have to ask yourself, are the lanes really that oily?
If not the
ball may be burning up. If you are truly throwing the
ball on heavy oil, then you will need to replace any heavy oil
ball more quickly than other
balls because they will soak up that much more oil. So whether it is a heavy oil pattern you are bowling on, or a pattern that doesn't have enough oil on it and the
ball is losing too much energy that will explain why the
ball seems to die.
Have you tried having the surface sanded, then having the oil extracted from your bite, then taking the surface up to 2000 and shining it up and see if the reaction returns, if so you aren't throwing it on enough oil for the out of box surface and should keep it shined up and
clean. If it skids all the way down the lane, then take it back to 500 grit surface and leave it dull and see if that doesn't help, if not the
ball is dead, give it to the youth league and buy a new one and that's how long you are going to have a
ball last with heavy oil.
