Winter storage

Hi everyone I will soon bring my 02' C4S to a storage garage. The garage is kept at room temperature during the whole winter. Ive read some advices here and there but I do have some questions. Theses are the infos I have so far: -Do an oil change -Use fuel and oil stabilizer (Storage defender from Driven?) -Fill the tires at maximum air pressure -Use a battery tender -First an oil change was done August 1st. Wondering if it worth it to do another one before the end of October? Do you think this semi-fresh oil will do it or should I replace oil and filter before storage and keep the same oil for the next season? Or keep my semi-fresh oil, send the car to storage with stabilizer and do an oil change next spring? -Anyone have experienced Fuel/Oil stabilizer? Can it create problems of any sort? -Just wondering if some have the maximum air pressure from Michelin Pilot Sport 2 N4? I guess I can found it on the tire? You guys have any other advises? Thanks!

Think this is the best bet as you suggest. (Or keep my semi-fresh oil, send the car to storage with stabilizer and do an oil change next spring?)

Yes to adding fuel additive, don't bother with an oil additive, waste of money. The oil in the car is fine to use, you wont need to change it next sprint, just a waste of oil. just take it out for a few good runs in Spring and your done. Store it as is and drive it next year. Next winter just do the oil change just before storage. I'd also suggest you give the interior a good vacuum and clean, remove the mats and place some silica bags around the car. You can pick large ones up off Amazon.

Dont forget moth ***** for in the engine bay and under the car to keep the mice out.

Your oil is fine. Change it when it's 5,000 miles old in 2019. Use StaBil. 1 ounce per 2.5 gallons fuel. Pump up tires to 55-58 psi.

Bounce dryer sheets all around engine bay, interior & Frunck. You will never get the moth ball smell out of it.

+1 for StaBil fuel stabilizer. Worked great for me. I'd also recommend washing your car and keeping it under a cover while in storage. And don't forget... the frunk (where the battery is) and engine bay are both locked electronically. So in the event your battery dies, you will not be able to access them to jump the car. Instead you need to follow the convoluted instructions in the owner's manual to jump the fuse box first to get them open.

I don't understand the tire advice. Are people running bias ply still? Any radial flat spots will disappear the first time the tires come up to temp in the spring.

The reason for the tire advice has more to do with the idea that most people have to account for the drop in temps and the loss of air over time (averaging 1psi/mo).

My advice is TO DRIVE THE CAR! Get some winter snows and enjoy it!

This suggestion is fine for people with the lack of fear for other idiot drivers. Where I live especially the first few snows of the winter people around here seem to have forgotten how to drive in winter. There are enough fools driving, again in this area, much less in less than ideal conditions. In spite of the above disclaimer, there are 996 owners who equip their cars properly and drive all winter successfully. So personal choice...

Idiot drivers are everywhere and every season. Just look at the recent spate of accidents on here. Nevertheless I understand the fear but I still suggest you drive it on days when it is not so bad. My C4 is a blast in the winter!

2x on the scented dryer sheets, work very well and they're cheap. I used to put them everywhere in the car inside and out and never had a problem plus the car smells great in the spring. Then I started driving it year round in MN, switching wheels and tires for the winter and love it. Car with good Blizzak snows handles better in the snow than most 4x4's until it gets too deep... there's idiots out everywhere summer and winter so you just have to stay aware.

Understood. Mine is a 4S but it stays in the garage during winter, my choice. I have two other vehicles that are much more capable in winter and would pain me less if some dork slid into it because of lack of skill in driving on snow/ice. It's just me. To each to his own decision.

Hi everyone Thanks for your advises! I wont use the car in winter as the season is quite hard here in Qc. I also have a 4x4 vehicule that can handle it well. On the other side just thinking about the car in deep snow make me dream! I will defenately use some dryer sheets in the engine bay and interior, sounds like a good idea. The frunk problem wont be an issue as I have safety cables installed. Thanks again

Hi Just a quick update, I decided to use Sta-bil fuel stabilizer and avoid any oil treatment. The car was parked for a couple of days in cold weather (Above 0DegC) And I got a weird clicking sound coming from the engine.(See attachment for sound clip) Just wondering is this noise is "normal' on a cold start or its something I should investigate right away? No difference in engine rpm during idle and the noise went away after engine gets hot obliviously. Oil actually in the car is Motol 5w30. Storage is in a couple days only... Im also trying to figure out a procedure when taking out the car from storage and came across something on the subject. A guys said he was removing the fuel pump fuse and crank the engine so the oil system will be pressurized before putting back the fuel pump fuse and do a start-up. Someone find that this make sense? Thanks

Could be anything: lifter, fuel injector, piston slap, rod bearing, exhaust leak. Have you tried remiving the serpentine belt to see if the noise goes away when cold?

I get you have to store it during the winter where you are at. I would be so sad to not be able to drive my car on the nice days though. Storing off-site would bring me pain too. At least on the days when I don't drive my 911 I at least give it a passing glance in the garage. Glad I live down south!
