All of the above points are well and good advice. Over the years I've read various scenarios along the same line at spring startup. Many years ago I was given a great bit of advice by an older friend of my father, a retired mechanic...if you plan on storing any car for an extended period of time, especially in the winter, always change the
oil and filter, replace and gap the plugs, fill the tank to the top and faithfully start and run the engine every couple of weeks until it comes up to operating temperature and on occassion put it in gear and move the vehicle. Remember this was back in the mid '60's. I have followed his advice over the years anytime I 've ever stored any vehicle, especially in the winter months, even V-8 powered ski boats and have rarely had spring restart problems.
Just some food for thought
