hi my w202 has been off the road since the beginning of October as I thought we were going to have a harsh winter with loads of snow/salt on the roads,anyway I want to put her back on the road to be honest I have missed driving her,the battery had been disconnected and has been on a battery conditioner all this time,is there anything I should do before reconnecting and starting her,should I turn the engine over by hand before cranking and should I do an oil change before starting.
