Don't start it... that is the worst thing you can do for a trivial short term storage like this. Here are the reasons why: 1) Most engine wear occurs at start up... why start the car unnecessarily? 2) One of the worst environments for an IC engine to operate in is during cold incomplete combustion (fuel wash on cylinder walls, diluted oil from unburnt fuel, cold clearances, etc.)... which you have while warming it up... why do this unnecessarily? 3) Cold exhaust system... condenses water out of the exhaust and can prematurely rust everything downstream... again... why do this unnecessarily? If you must start your car while in storage (i.e. a fire in the garage, need to move the car to access something you didn't plan on, etc.) then the tips to warm it up fully are correct but you will have done all the damage that comes with a start. I am not sure where the big panic comes in all the car circles with sitting a car for periods measured in months. Just make sure the car is fully warmed up before you shut it down for the winter in October (or whenever you quit using it) and have fresh oil in it. A trickle charger on the battery or a once / month 10A charge is also good advice.
Good advise. No need to fog the engine, but if you are concerned with flash rusting in the cylinders try this. Add a qt of MMO to the gas tank at the gas station before filling the car. Fill it up drive it for at least 30 minutes park it and leave it. The excess MMO will coat the combustion chamber nicely with a thin film of oil. If you do decide to drive the car no problem, but try and run it at least 30 minutes before storing it again. If you don't have MMO or prefer something else a good dose of TCW3 will also lay down a nice coat of oil in the combustion chamber. I've never used TCW3 for storage but I would think 4 or 5 ounces/10 gallons of gas for storing a car would be fine. Be careful with the TCW3 it can foul plugs. I've never fouled a plug with the MMO, even as a fogging oil.
