How does lane condition affect my bowling?

Okay so I’m fairly new to bowling and I’ve been able to curve my ball really good now. Yesterday I went bowling and it would not curve. I asked one guy and he said they just oiled them today. Wouldn’t my ball curve more if there is fresh oil? When I bowl in tournaments they always oil them and my ball has usually curved just fine. Could there have been something up with the oil? Maybe too much? And does a dry lane curve a ball more easily than a freshly oiled lane would?
