Need some advice.  I just picked up a leftover '04 with no miles.
1). When storing it for the winter can I put a smart charger on it without pulling the battery out??  Will it disrupt or fry any electricals/sensors/anti theft systems?
2). The car came with synthetic oil.  I've always used fossil oil when breaking in new engines then switched to synthetic.  This allows(at least in theory) for a better mating of valve seats, rings, bearings, etc.   I may be dating myself with this question.  Should I use fossil oil during the break in period?  
Thanks
