Winterizing your SL

Getting real close here in Sun Valley Idaho to putting car away for winter.
Was just wondering what those of you do when retiring car for 5 months. In past I have just waxed and over inflated tires. Anyone use fuel stabelizer? When it gets to 10 degrees I flip on garage heater. Any other thoughts or ideas?
Thx in advance!! FG

It is a very good idea to use fuel stabilizer. You may want to put a trickle charger on the car as well, and don't forget to do a fluid change when you take it out of hibernation!

In AZ what we do to get the cars ready for the winter is take the roof down!

I'm always surprised to read about car enthusiasts who "garage their car for the winter." I always run my car at least once a week in the winter. I've been told it's better for the car. Plus, unless there's snow on the ground, I want the enjoyment of driving my car year round, even if it's only 4 days a month in the winter. Just a thought.....

My SL is my daily driver all year. Unless there's heavy snow, it's my commuter choice. Of course snow tires after Thanksgiving are a must for me.

Maintaining batteries

I'll park my SL55 for the winter at Nowember 1, my concern is the maintain the batteries as there is two. Is ther one point some where to connect the charger so the two batteries get maintained? Please let me know where to connect the charger, picture. I have a advanced charger that is perfect for maintain batteries.

Mine will go into a storage unit tomorrow. I picked up a nice NOAH cover on Ebay last week and I've washed her and topped off the tank (with $2.49 dollar premium!) I plan on just running the car a day or two each month to keep the batteries charged and to prevent flat spots on the tires. I'll miss her but it makes me enjoy the top down days even more plus it keeps the miles from piling up on the odometer.

Time to fire up the ML!

SpainSL500,

I would love to be able to drive my car all winter, but Sun Valley is a "destination ski resort" the first destination ski resort in America going back to 1936 and it gets cold here. -22 degrees two winters ago in January and up to 10' of snow. They also lay down salt on the roads which destroys the paint, so alas, into the garage until spring. I do start it once a week and use the CTEK battery charger. Question for anyone else on this thread. Normal tire pressure is 26 frt and 29 bk. What are you inflating your tires to for winter storage? Thx!

+1 Had stored my 745Li 2 years ago in the storage, hadnt driven it for 5 straight months....winters in toronto are pretty insane....after the winter by spring time the car used to shake a lot during start-up....after several visits to the dealership....they ended up replacing the whole engine on that car...
found out from the leakdown test that one of the cylinder head walls had started to peel...due to fuel somehow making its way in there...and started to react with the wall elements of the cylinder....

So anyways...even if you store...point being dont forget about it and just hibernate....please start it up, drive it if its a clean cold day....giving it a nice run, prevents flat spots on tires...
also in spring time, someone already mentioned this, but do an oil change, as oil sitting for long, loses it viscosity. I know I know the oil changes dont need to be done that frequently, but for a low mileage winter stored car, its a different scenario

A sad ending to a great summer... This makes me so envious of you southern and south western guys...

Oh well, I'll visit her every two weeks or so just to fire her up and and take her for a quick spin.

How far away is April anyways?
