How about an its rx7 stored in a non heated garage just south of charlotte. Car currently just has water and water wetter in it. Garage may reach sub 32 temperature say 20-30 nights over the winter

Drain say half out and add some 50/50 and run it up to temp and tuck it away?

Drain say half out and add some full strength and run it up to temp and tuck it away is my vote (that's what we do)

Make the last tank of fuel,100LL AV gas. Add enough so that the top of the tank is covered, but not all the way up the filler neck. 100LL Stores very well and wont stick the pumps and injectors. (any steel tank or steel fuel line car, should use non Ethanol fuel.)
If the cam is large, back off the rockers or cam, lube the cyl per above ATF or dino(non syn) oil.

Per mazda, fog the engine, add Anti freeze. Drain a gallon add a gallon.
Better, send the car to FL. and race all year.
