To Start or not To Start while in Winter Storage?

[Boxster33]

Hi All, I willl be storing my Boxster this winter and the dealer mentioned that I should start the vehicle every 2 weeks so the seals don't dry out. I was always told that cold starts were bad for an engine and we do get cold winters here in Toronto. I Plan to store the vehicle for 4 months December-March.

Any Thoughts?

Hey I am in Toronto too....I lean towards not starting the engine and then turning it over numerous times before starting it spring.

Before putting the car to sleep for the winter, change the oil and filter, add Stabil to your tank and fill it, drive the car a few min. to circulate the stabilized fuel, clean the car inside and out, hook up a battery maintainer (NOT a trickle charger), and then leave it sit. Do not start it unless you are going to drive it for at least 20-30 min.

While your car is in hibernation, start looking for a dealer that knows what they are talking about…………..

I do NOT start mine. I have been storing it like this with excellent results the past 3 winters. I store from mid October to early April.

There are some excellent winter storage advice threads here. Search keywords "winter storage".

Keys to remember:

fresh oil
wash & wax
stabilize fuel- tank full
over inflate tires to 58 PSI
Porsche battery maintainer
desiccators
park on a sheet of plastic
don't engage parking e-brake, block wheels
car cover
Turn off insurance, except Comp. (fire & theft coverage)
In Spring, hand crank engine by pushing in 5th gear, until you hear engine turn over, then fire-up with key. Then take a 400 mile road trip, buy fresh fuel

I don't start mine but I do use jacks or stands to avoid flat spotting the tires.

It is a bad idea to let the suspension hang on these cars as the strut shafts can corrode, amongst other issues. And I wouldn’t worry about flat spotting the tires; all tires flat spot while sitting for even several days; if the flat spots don’t go away after a few min. driving, you need better tires………….

First, aren't the strut shafts stainless steel? With a light coat of oil on them, why would they corrode after 4 or 5 months in storage?

What are the "other issues?" Please be specific. I stored my car on jackstands last winter to no ill effects. Might do differently this winter, but only if there is a good reason.

The shafts may indeed be stainless, but they'll still attract dust, possibly dirt and when compressed, will abrade the upper seal on the shock body, contributing to early failure.

Also, when fully extended, the shocks support the weight of the suspension and all the unsprung weight. This places a lot of tensile force on the shock which it was never designed to support - shocks are designed to endure compression forces, not tensile ones.

The shafts collect dirt and they do corrode, leading to premature failures; they also were never designed to carry the weight that is on them with the suspension hanging; and with the suspension hanging, your rear axel boots will be subjected to compression and pinching, shortening their lives................ Porsche had a TSB about not doing these issues years ago, indicating they would not warranty parts damaged by “improper storage conditions”.

Let the car sit on the ground, it will be just fine............. We have a local dealer that stores cars for selected customers (GT 2’s, GT 3’s, Carrera GT’s, etc.); they are all sitting on the ground, and they do not over inflate the tires either........

I agree....with all these steps fill the tank and stabilize it.....I park on dense foam pads (plastic sheet as well) that deform instead of the tires. I have the tires pumped to 50 psi

[Lil bastard]

Don't start... Best thing!

Hi, I start the car every week letting it run for about 15 minutes.

Fill Tank and add Stabilizer

Inflate Tires to 70 psi.

Put stoppers in front and rear of wheels, No handbrake

Fresh oil and filter

Fully charge battery every 2 weeks

Wax once a month

Those of you who park on foam -- where do you get it? What type/density? Thanks.

I've never started mine in the winter: Fill Tank. Stabilize gas. Tires to 45-50. Porsche Battery Maintainer. Great results.

I got it at home depot; enough for pads at each wheel; it was pink and very dense...it took the weight of the car....an tire impression was made half way through its thickness over the course of the winter; so it looks like it did its job....no flats spots with 50psi. Too soft will be useless

make you make pieces big enough to drive onto!
