Winter storage / fuel stabilizer

[Darwins Child]

Our car is a nice-weather-in-the-summer-only toy (and boy is it fun). I don't even drive it if I think it's going to rain and this summer no rain touched it.

My city being Edmonton, the snow can start flying at any time now. Next week there's a good chance of it.

At first each snowfall will quickly disappear and the streets will dry, but, in a few weeks or possibly even days, snow will become a problem at intersections and the city will start spreading sand at least in these locations. When that happens I'll put the car into its winter-storage position in our garage (with our snow-blower and back-pack blower sitting ready-to-go between the Z and the garage door, instead of the other way around). There the car will sit until perhaps mid to late May of next year, so perhaps 7 months.

I will install an "intelligent" battery charger to keep the battery topped up at all times.

I intend to add fuel stabilizer to the fuel in the tank. Presently there is half a tank of fuel in the tank, so I have two questions for those of you who use fuel stabilizer.

1. If you were in my shoes, just exactly how would you add the fuel stabilizer so that it ends up being well-mixed in all the fuel?

2. After adding the fuel stabilizer to the tank, assuming that the stabilizer is well-mixed in the tank, how long should the engine be run to ensure that the stabilized fuel has made its way from the tank to the engine and, therefore, is "resident" throughout the entire fuel system?

Thanks.
