This question already has an answer here:
Quick question: I have a 2008 Honda Civic. It has been sitting for almost 4 months now, and there will be no chance to drive it for another month or so, making it 5 months in total. I believe the oil was at an okay level, along with the gas when it was left. What type of problems should I expect? Should I bring a mechanic with me when I go to start it up for the first time again? I am completely incompetent when it comes to cars so I will likely need someone else to do any immediate work on the vehicle, should it be required.
