Fishing Pole Maintenence?

[Ffteyeri]

My fishing pole has me a bit worried lately.. It is barely relieving the line when a big fish hits it and when it finally does, it lets all the line out.. The actual line is also getting hard and is almost like twine or something now. So my question is how do I lube up the reel to make it all work smooth? And is there a way to make the line better, like adding some kind of very thin mineral oil or something to it? Maybe vegetable oil would be better. I am not sure on if this is a good idea or not though so that is why I came here. Maybe you can advise me expensive fishing pole? I play online casinos real money, that I found here https://casinos-advisor.com/ and can buy expensive pole.
