As the title says, this is a pretty basic question.
I have a 2000 Forester S with a little over 30k miles. I always try to change the oil every three months, but in the last few years I've had difficulty doing that for various reasons. It's been more like every 5 or 6 months. On the other hand, I am hardly driving the car right now. If I put 100 miles on the Subie a month that would be a lot.
I know tht oil breaks down even when a car isn't being driven, but am I shortening the life of the engine significantly by extending the oil change intervals. Btw, I live in the Northeast U.S. if that makes a difference in the matter. (cold w/second snowstorm coming this weekend they say) At least the car is garaged.

I really don't think it matters. What kind of oil are you using matters more.

I'd say it has NO effect for six months. I wouldn't start worrying about the oil breaking down until about 12 months, definately not before.

I'm with applegump, I've always felt that twice a year was the least frequent I'd ever go bewtween changes. Especially here where we have extremely hot summers. However, if this is going to be your regular pattern for a long time, you might consider changing to full synthetic and the best filter you can find (silicome anti-drain valve). I suppose 'extended drain interval' can be interpreted to mean time as well as mileage. You might post/search over at www.bobistheoilguy.com
You might consider adding a gas dryer occasionally and trying to keep the tank over 1/2 full to reduce water condensation possibilities.

You are fine as is, but don't push it too much farther.Oil is pretty cheap and a lot cheaper than other alternatives.

Thanks all for the responses!
I will be getting the oil/filter changed asap. Btw, I have only used the Subaru dealer for service since owning the Forester, so I assume they use the best oil for the season.

Thanks again!

They use the cheapest oil they can buy in quantity and charge you top dollar for it.

At least, every dealership I've ever been to does this. :boohoo:

You can bring your own oil and filters in.

I bought my M1 10-W30 at walmart and my Pureone filter at pepBoys and took them to my indie mech. 10$ later I'm out the door.

I frequent a local shop that charges me $10 to change and dispose of oil and filter if I bring in my own. Not bad when I'm in a hurry.
