5) Make sure to clean and condition all your car’s interior leather.

This is the best time to do a thorough job to ensure that your leather remain supple all year round!

6) Condition all Rubber and Plastic Items

Make sure to use a conditioning compound on all exposed rubber and plastic items on the exterior of your Porsche. This will ensure that they do not crumble or crack with the humidity and temperature changes.

Porsche enthusiasts swear by the German made Gummi Pflege Stift !

  • Conditions all weather seals around doors, hood and trunk
  • Temperature resistant for long-lasting protection
  • Prevents rubber from drying and cracking
  • With built-in foam applicator for easy application
  • Made in Germany

For rubber seals in car doors, windows, and boots, Gummi Pflege offers long-lasting freezing protection. It also offers true, deep-down safety conditions, helping to extend the life of rubber seals, gaskets, and trims, offering protection from the sun’s cold, heat, and UV radiation.

If rubber seals around windows and doors go untreated they will deteriorate over time. As a result of changing temperatures and high UV sunlight exposure, the rubber starts to dry out, crack or shrink. When this happens the integrity of the seal will fail and lead to further problems such as squeaks, whistles, draughts, and leaks. The original luster is lost and the rubber continues to perish.

Unlike many plastic and rubber treatments, Gummi Pflege doesn’t simply buff rubber to look new. Gummi Pflege provides real, deep down protection, helping to prolong the life of rubber seals, gaskets, and trims, providing protection against cold, heat, and UV radiation from the sun.

7) Change Your Engine Oil and Filter before you Winterize Your Porsche Boxster

This is CRITICAL is using an unheated location for the storage of your Boxster!

10) Set Tire Pressure

The most common problem encountered when winterizing and storing a car is that flat spots occur on the tires. Tires go flat on one side for carrying the weight of the car for an extended period.

To avoid flattened tires, overinflate all tires by approximately 8-10 psi. 
Overinflate the tires when the tires are cold, therefore you won’t get an inaccurate reading. Don’t worry about using jack stands or lifting the car.

11) Gas

Ensure your gas tank is full of premium fuel to prevent condensation and reduce tank airspace.
