How many times can you safely reuse a spark plug with crush gasket? I drive my car in the summer and park it in the winter. I like to spray preservative oil in the cylinders for storage. But the plugs are iridium tipped long life. I don’t want to throw them out every fall. Thanks in advance.

Doesn't matter as long as they are torqued to the correct specification (about 18 ft/lbs)
