Default Procedure for starting hibernated cars?

As stated. I store my cars for the snow months. I have a procedure I follow to start the air cooled and 928 cars but this is my first Direct injected engine that I have allowed to sit for 4 months. Do I pull the fuse for the fuel pump crank the engine to build oil pressure or is there a procedure anyone recommends?

Thx

I set the garage thermostat to 78 about 24 hours prior. Then, turn the key and go.

No worrying about lack of oil. Maybe I am overthinking the newer cars but the air cooled you want to build oil pressure before starting. My garage is climate controlled with radiant floor heat so all good there.

I don't think you really need to do anything on the DFI engines. Oil pressure builds extremely quickly anyway. Tire may be flat spotted if they sat for 4 months unless you used cradles, though.

Agree.

Assuming his tires were over-filled to 55-58 PSI, as they should have been, this is a non issue. Cradles are great for the cradle sellers, only.

Regardless, this so called 'flat spotting' is completely reversible on a modern tire after a heat cycle.

One thing, after the first start after hibernation, give the car a good walk around. Be observant of any new/strange sounds and smells.

Its getting new MPSC2's next week if the snow disappears. I overinflated the tires to max pressure prior to storage and flat spotting isn't much of an issue with the radiant floor heating and carpeting they sit on.

Glad I asked anyhow. I wasn't sure if there were any special procedures for DFI engines.

I have 5 to pull out of hibernation the air-cooled cars area bit more work.

Assumed you stored the car with fresh oil? And stabilized fuel (1 ounce per 2.5 gallons StaBil)??

I made the mistake of leaving the tires at ~30 psi for a month or so with a non-heated (and very cold) garage and the first drive or two were pretty rough. They did indeed correct to round, but it felt like a completely unbalanced tire for a while.

Yep it is a bit of work to store these things. At 12 quarts of oil per air cooled it is not cheap either. Although it is not as critical with the newer Stainless dry sump tanks vs the earlier copper ones, just a creature of habit owning these cars since the 70's. StaBil is only good for about 6 months though. I try not to let them sit that long but mother nature is not being very forgiving.

Normal. And common storage error. Next time pump up to 55-58 PSI. No mo flat spots. It does take a l o n g time to blead out a 20 inch 305 tire. LOL!!

I used to store my Spyder for 5 months when living in NE and KC and I would just fire it up when ready to go for that first drive.

I did take it easy on the first 20 minutes of driving to let all the fluids coat everything.

You can damage an air cooled engine resulting in costly repairs. Scoring of the cylinders and damaging the bearings. I guess I am too busy thinking dry sump.

Unfortunately woke up to this.

I was going to have my pool opened this week but I guess not. Looks like the boxster and other cars will need to wait another week as well. Talking more snow this weekend.

The Macan loves it though.

OMG, that looks terrible. The winter that will never end. Re procedure for starting a vehicle that has been in storage for several months, I regularly have many vehicles parked in garages during the winter mos and when Spring finally arrives I just turn the key and drive away. Never have experienced and problems from what I can tell. And those vehicles include a 930 turbo, 981 Cayman, Ford P/U and Toyota Prius. Maybe if they were parked for a very long time I would approach it differently. Just my thoughts.

I'm with the "turn the key and go" crowd. My car lives in an unheated garage during the winter. I do start it once a month to circulate fluids and charge the battery, but I never do anything special. For the money I paid to own a Porsche vehicle it had better be able to do the same **** a $20k Honda can do.
