Default long-term storing of 991.2 TTS

With the Ohio winter around the corner I thought I'd get a head start on how I'll store the car for 6 months or even more. Any recommendations how to properly store this car?

I do everything but the fresh oil. I usually change that again in the spring. Is it bad to let the car sit with old oil? I just changed it and the filter at the 2000 mile mark in August.

Depends how the car was driven in those 2K miles. For example, track miles, no. Short commuting miles, no. Longer spirited runs, oil got up to temperature on regular basis, fine.

When ‘ballooning’ the tires to prevent flat-spotting, check the tire sidewalls for maximum inflation pressure and do not exceed it.

That has nothing to do with over inflation for storage purposes. The two are unrelated.

Is the detailing needed? How about a simple wash? Also what do you mean by blue marine stuff?

Needed? Probably not. Washed for sure, since you never want to cover a dirty car. I just like jumping into an essentially new car come springtime.

The blue StaBil Marine stuff is better for fuels with ethanol. The old red stuff is fine too, but dosed higher at 1 ounce per 2.5 gallons.

We usually see eye-to-eye on these things.

Right now I have 52+ tires in my garage. An arbitrary sampling of 4 tire sidewalls gives a range of maximum pressure of 40 PSI to 51 PSI. I find the 40 PSI max surprisingly low btw. Nevertheless..

Your 58 PSI recommendation is arbitrary my recommendation is not. Decades ago the (IIRC PCA) published recommendations were 8 PSI over normal running pressure and not-to-exceed max-listed pressure whichever was lower.

With typical cold pressures ranging from roughly 31 PSI to 47 PSI (for a 991 Turbo) depending upon size, load setting etc, why does 58 PSI make sense regardless of anything else? If it is Ok, why 58? Why not 59 or 56? Why not a relative over-inflation from cold pressure?

I've never seen anything to suggest that inflation beyond the maximum sidewall is OK for storage. Do you have a reference?

I drive my 911s all winter. Sure sometimes it may sit for up to 10 days but that is rare. I put a battery maintainer on when it sits.

I can remember reading my old 993TT and 987S owner's manual, and seeing the range of 55-58 used. I've not seen this info in my 991 manual.

Not knowing your location, research places like Sunset Imports and Suncoast porsche in the USA, and Carnewal in Europe.

Perhaps you missed the OP's title, but this thread is about long term winter storage. Not driving a Porsche in the winter. Maybe you can start a new thread.

Covercraft makes - as far as I know - the vast majority of car covers in the US. Their covers are resold with slightly different branding by many many retailers. Their website doesn't inspire confidence that they know the difference between a 991 and a 991 Turbo until you 'add to cart.' The Griots site does though. They're a few dollars more expensive than ordering direct from Covercraft, but I have had nothing but stellar customer service from Griots and I've order A LOT of covers over the years.

For purely in-door storage I like the Form-Fit covers (Griots link.) If you want to be as **** retentive as I am, use a Weathershield cover over the form-fit cover. The Weathershield is washable at home so when it gets dirty it is easily washable and keeps the ultrasoft FF cover from needing to be washed (for years.)

Thanks for that. There was something about 5x PSI and sidewall pressure that jogged my memory. Your reference to the manual was the missing link.

It is in the manual: 50 PSI which is also the max pressure listed on my TT’s sidewall. Coincidence maybe. The Michy’s on the 991S are 51 PSI.
