...as to starting up a little-used car and running it around the block once or twice a month, old car enthusiasts generally say a 50 mile run should be preferable because a cruise of that duration will get all the fluids up to operating temperature, slosh lubricant everywhere it should go, charge up the battery, etc. A "cold start" where an engine goes from dead, to running, to being shut down cold again, is often cited as shortening the service life on fire and other emergency equipment that never gets a chance to really "warm up" or cool down after use.

What are your thoughts? What's the minimum you can do for a car that stays largely "parked"?
