I have a 1951 Dodge Coronet, with Gyromatic, and I was wondering what fluids to use (oil, transmission, ect..) as the ones listed in the owners manual are not avalable at my local auto parts store. Also I live in Minnesota, and plan on driving in winter, so I can't be running any light weight oils. Can I use good ol' 10W30? Do I have to order something special online? <img src="http://forums.aaca.org/images/graemlins/confused.gif" alt="" />
