Steel Seat Post

I heard dis-similar metal cause corrosion.

I verified with a magnet that my steel cruiser has steel seat post. Looks shiny. Feels slippery. Like chrome plated.
  1. Is it necessary to grease this seat post?
  2. How much weight can I save by converting to a aluminum seat post?

Yes grease it, always a good idea. Personally, I apply the grease to the inside of the seat tube instead. Less messy that way.

Weigh it and compare that to any posts you may be considering while shopping.

Would look at how much the bike in total weighs, and then judge if replacing the steel seatpost is worth it before spending any money on it.

If your seat post is in good condition, keep it and spend your $ on something else. Like SquidPuppet said, grease it.

IF you replace that heavy steel seat post with an aluminum post, get a post with the integrated clamp, and toss the funky steel clamp that is used with the steel post! you will be removing weight from up high on the bike, and the missing weight WILL be noticeable! the bike will feel lighter when riding, due to less weight far away from the center of the bike.
M/C Dirt bikes, and later, street bikes are now engineered to CENTRALIZE MASS... this makes them SEEM lighter and more responsive to changes in direction... and if you shop a bit, you can find some fairly light seat posts for a decently low price, too!
