Ha! 30 degrees is NOT cold! You can almost melt ice at that temp. But seriously you can look into many different heat devices for extreem cold. An installed block heater,a dipstick engine oil heater,a spliced inline coolant hose heater,a magnetic block heater. Any of these will help. In my old truck I used to keep a space heater in the cab with an extension cord run to a switched outside outlet and turn it on an hour before I went out to start it. It even helped defrost the windows by doing that. Just remember to unplug all this stuff before driving away.
