My 70-200mm L lens is making noise as I turn it, is there a way to oil it

so when I 'm video recording the birds in the backyard, as I turn the zoom, there is some amt. of noise. It's slightly annoying. Is this something a local camera repair store can do or is this something that a drop of oil can fix , if so, can an average person do it?

Probably depends on where the noise is coming from - suggest you get a lens tech to have a look at it rather than attempting a DIY cure unless you're either very capable with a screwdriver or willing to risk scrapping the lens.

I wouldn't suggest oil as you have no control over where it goes... the factory lubrications appears to be some sort of grease.
