Not a lot miles to be burning oil.
You commute is short so you should be checking your cam chain adjuster soon... very soon.
Even though your commute is short, 2 months w/out checking your oil is a bit optimistic.

I checked dirty oil and cut oil filter found no metal pieces.
I am hopeful than yesterday and open oil filter cap more oil drain out so looks like whole situation is better than before. Thank you all for support

Kyle,

How much oil was drained? Did you only drain it from the filter box or did you remove the drain plug on the lower left side of the engine?

The guy I bought my 08 from "drained" the oil from the "drain plug" on the front left side.  He said not much came out.  

He put two quarts in and didn't see a line in the little window so he put another quard and then another.  When he was done the bike wouldn't start so he sold it to me pretty cheap.

I use highway to commute. Speed is normally 100 ~120 km/h or 60 ~ 75 mi/h. Little oil level glass is really suck.  I wish Suzuki make simple plastic dip stick.

At last I got open my new Clymer manual!
It says, 1,8 liters for oil change.
And for oil change and filter change  2 liters.
1-0.9 liters is ofcourse half of what supose to be there.
But, if its not broken, its not broken!
I think that are margins to, it cant be that some less DL of oil could do any harm, if one not doing a lot offroad!
Comuting seems to be fairly level rides, the oil have to get below the intake of the oil pump to suck air!
And how to use the inspection glas on the right side of the engin.
One should have the bike on level ground, have the bike standing right up.. not on the side stand.

Easyest way is to have somebody  sitting on the bike in riding position, then you can inspect that glas, in the middle is prefered and recomended by Suzuki.

In any way, you have nothing to lose, put some new oil in it and change oilfilter, it could be one of your better buys, try it out.

I use a wheel chock for storage and maintenance. If you need to raise the rear tire, put the chock on the front wheel and use a floor jack. Need to raise the front, reverse the process. The bike sits level and stable.
