Condensation in engine oil: How often do you change yours?

[noggythenog]

This is my first winter storing my bike, new rider & summer rider only.It's hard to make a decision with all the confilicting advice about, my on call adviser (aka dad) has said not to worry about it all as he's never had any problems in all his years of biking with just leaving the bike over the winter and getting back on it in the summer but for what it's worth i decided the following:-

- Gave bike last decent run,filled tank with Super Unleaded, washed,acf 50'd,into the shed. (end of October)
- Battery out,charged once indoors since,seems to be fine but is new,stored in the house.
- Havent started her up.
- Old oil is still in the bike
- End of March i've got 2 weeks off,hopefuly for biking, will change the oil & oil filter, wasnt going to start bike up until the new oil
  was in the engine so that any issues with water in oil wont matter as it wont be there, not sure about this though as i read that
  warming the engine a bit helps it come out easier, im gonna try changing without pre warming though.
- shall add some ever controversial activ8 to the fresh oil  :eek
- first run out will be a couple of hundred miles and a good blast to get the cobwebs out.......i hope :\

some here are  saying put fresh oil in before storage but what difference does that make if it's all just in the sump anyway :think
