Antifreeze / Oil

[UFR131]

Getting close to end of rebuild and need to start filling things up !
   
   1. Could anyone please advise on the best make of antifreeze / inhibitor to use to avoid any corrosion issues in an AC engined Ace? Also what concentration of antifreeze is best.
   
   Also is it best to leave this in over winter layup or drain it down ?
   
   2. Recommended make of engine oil ?
   
   Many thanks,
