Conveniently, The Chlorine
molecule in salt and the Hydrogen molecule in water just love
one another.
Unfortunately, those two molecules
combine to form HCl, otherwise known as dilute hydrochloric
acid.
Dilute acids are very often more
corrosive and damaging than concentrated acids.
Which is why those of us in the
Great White North who want to preserve our cars, have
no choice but to
store them for the winter.
Or maybe we could all move to New
Zealand, for example, where the temperature remains moderate
all year round
and 25 year old cars in good condition
are quite common and still in use.
It's cheaper, by far, to buy a winter
beater and keep the good ride locked away. Even aluminum
is not immune to HCl
corrosion and in consequence, those
expensive wheels should be stored lying flat in favour
of mounting steel wheels
and snow tires, if you decide not
to store the whole car. For a car such as mine, the storage
procedure is quite simple:
1. An oil change, unless the high
priced synthetic is comparatively new.
2. A good waxing and cleaning inside
and out.
3. Half a tank of gas with fuel
stabiliser added. Run the engine until the stabilizer
has reached the injectors, which may take
about one minute or so. Five minutes
is more than enough. Since older classic cars run very well
on regular gas, the half tank
of gas allows me to run down the
road in the springtime and top up with high test until that
whole tank of fuel is gone, then I can go
back to using regular fuel. If your
car uses high test anyway, it's not a good idea to have
too much fuel in the tank.
4. Inflate the tires to a safe but
higher than normal pressure. In my case, I usually go up
to 38 psi. Do not put the car on blocks,
which exposes the shock absorber
pistons to moisture and is just not worth the trouble.
5. Disconnect the negative battery
terminal and write a note to yourself in next years' calendar
to charge the battery for about
four hours on the first of each
month.
And that's it. Do NOT be tempted
to start the engine frequently for a few minutes. This is
a really bad practice.
In the springtime, I pull the fuse
for the fuel pump and crank the engine over until some
slight amount of oil pressure starts to show
on the gauge. Since I use 5w40 synthetic
AGIP, this does not take long. I then put the fuse back
and hey, presto the engine fires well.
I haven't had any problems with
this method of storage in the ten years I've been doing
it.
But there is a new wrinkle around
that makes some of the advice I just gave you a very bad
idea.
In the case of late model cars such
as BMWs with I-drive or Mercedes with the Comand system,
or any car with a lot of electronic
controls such as stability systems,
never, ever disconnect the battery, or allow it
to run flat. If you do, the car will need a full day of
reprogramming at the dealership
and it will have to be towed there!!
Equally, if you have a radio that
is theft protected and goes into "fault" mode if
the power is disconnected, make SURE that you
have the restart code for your particular
unit.
To avoid all these dramas with computer
programming, I recommend the use of a 1 amp trickle charger,
connected permanently
to the battery. If your storage
area has no mains power, then you have no choice but to
start the car every two weeks or so and
let it run for about twenty minutes.
Remember, snow is not harmful to
your car, but salt is, so stay in your driveway or somewhere
else where salt slush is not in
evidence.
