Mountain Bike Quick Release Skewer

Do I need to use grease on my bikes quick release skewer?
I just bought my 2 disc brake giant mountain bike online and I need to put the front wheel on the quick release bar (skewer?) came seperate so I have to put that thru the tyre and attach the mechanical disc brakes. Do I really need to grease it? If so can I use any household or auto oil? Also which side should the quick release lever be facing? Thanks.
Does the release lever move? is that why you grease it? I want to use the bike now but I can put the grease on later.
Oil will run out and get on your disk brakes. I bought a tub of multipurpose grease at Walmart for $5 I use it for every bearing on the bike, pedal threads and other screws. You want to put a layer of grease on the skewer also. Put the skewer levers on the left side on the bike. A spring goes on each end with the smaller end toward the wheel.

Edit:
You can put grease on later, it’s more to prevent rust. You want to be sure to grease the pedal threads so they don’t cease up. The grease also allows the pedal to be torqued correctly.
