front suspension fork maintenance

Hi folks,
I have a Claude Butler Urban 300 hybrid bike. It's quite old, approx 10 yrs, and have stripped the front suspension forks for cleaning.
Can anyone please tell me if I need oil for the forks?
It looks to me as if there has only been grease used originally but any research I have done always refers to oil.
There is a rubber plug in the bottom of each fork approx 3 inches long.
Cheers…….Gary.

Are they springs or elastomer? Unlikely to be air.

At that age I'd guess they are short travel elastomer.
