Hello All,

What are your thoughts on changing the oil before my 997
sits all winter (except for a few intermittent drives, weather
permitting)?

Some say before, others say change it in the Spring.

id rather change in spring, so i have new oil circulating in my engine

I've always done it, supposedly it gets the acids out of car. Don't know if that's true, but it's easy enough to do and doesn't cost a fortune.

interesting, hadn't heard of "acid buildup" before, but this 1965 issue of popular science discusses it: http://books.google.com/books?id=LSY...20acid&f=false

The rule is to always change it BEFORE you park it for awhile. Imagine if you will, moisture in the engine oil, or in the brake reservoir,--being allowed to sit and be in contact next to untreated steel. Do beforehand to ensure proper protection. In the Spring the car will be ready to go.

Also, consider putting in a fuel stabilizer. Fuel is the bigger issue, as it is formulated for certain climatic conditions, and if parked for some time, loses much of its potency.

Thank you all for your replies.

That's another good issue---should you fill the fuel tank completely
up for the winter or leave it closer to empy?

I understand that it s good to fill up and add Stabil to the tank ( beforehand).

If its close to that time I would do it. If you just had it done I would wait.

Even better, just drive your car in the winter. On days the ground is dry, take it out.

I agree...the oil change depends on when was the last time you changed it and how often to you realistically think you will take it out.

I would set up the battery maintainer if the car is going to sit for days at a time.

I always change the oil BEFORE and store the cars with a full tank of stabilized fuel.

I wouldn't survive a winter without being able to drive the car. There are no dry sunny days in your winter?

brendo

why wait for dry, sunny days? drive the thing all winter and you won't need to worry about it.

BUT, get some all season tires. those high perf summer tires are like driving on roller skates when it's cold out.

I am wondering......would it be better to stabilize the fuel for the winter and leave the old oil in the car? Does it make sense to wait until Spring and use the entire tank of stabilized fuel and then change the oil?
