Fisrt thing I do is rainX the glass, pack insulation in the shaker inlet and then put the snow chains on the BFG's
I've been doing the same procedure for years.
Overinflate the tires (45lbs)
A mix of stabil & marvel mystery oil in the tank (full tank)
Battery goes in the house.
And the part that get the most puzzled looks.....
A bed of charcoal under the car... yes thats right charcoal. DO NOT USE THE MATCHLIGHT KIND. I use the cheap in-house brand from the Pik n save. Or get it @ sams or costco
I have 2 reasons
Charcoal soaks up humidity/moisture -maybe not an issue @ 10 degrees but your garage floor does sweat w temp changes
Mice around here absolutely hate it! I have NEVER had a mouse issue on any of my collector cars ever. Now I'm not saying I've never had mice in the garage (I have 2) (rent a space from my neighbor for the BIG GIRL). No cewed wires/turds/condo projects in vents ect.
Another note on the charcoal- It usually lasts me 3 years. You know when it wont hold any more moisture when its real soft an powderery. Often turns a grey color like its been used.
Come sping I crank 'em for 2 minutes to get the oil flowing before start up (take off coil wire)
This is just me, but its worked so far (20+ years)
