How to properly store my car.

I will be leaving the country for about 5 months, and I am storing my car in a storage unit. I know about changing the oil, overinflating the tires, the basic stuff. Should I worry at all about the internal engine parts rusting? I wont be able to start it either, is that a problem?:flag:
 
disconnect the battery,run lucas in the tank (the fuel treatment lucas) it has top cylinder cleaner and lubricant,careful not to put it in a storage that has woods or a field close by,put rat poison down and get a car cover.
