I was told by a legendary mechanic here in Mass., that if you are going to store a car never start it during storage time.
he explained how the friction in the piston cylinders always creates condensation and how every block always holds moisture. So when you start your car it condensates and then turns into rust, therefore acting like sand paper when you start it, so if you do that once a week it is only harming the rings and other components in the cylinder.
I thought he was crazy but then he took it 1 step further and grabbed a wrench of his tool box and handed it to me to make sure it was not wet in any way, then proceeded to take the torch out and heated it up and out came the moisture and off course rust to follow.
Don't know if this is true or false but I believe the theory after the demonstration with the torch and never start my Viper. I have it off the ground, battery conditioner and put a good quality fuel conditioner in it and no problems to date. I do drive it maybe 2 -3 times during the summer for car shows.
Just my 2 cents from the old timer.
