Oil change again, How often

[88porsche911]

Just wondering how often everyone does oil changes. Manual says every 7500 miles I guess because it takes so much. I see no reason to change it every 3000 since when I check it every 1000 or so it does not even start to change color for a couple thousand miles. Mine burns about a quart every 3000. I do not beat on my car at all, just the occasional redline here and their. Also, does anyone know why Porsche is the only one that does not want you to warm your car up before you take off, just curios. Thanks for the info

I have '92 C2. The manual says to change it every 15K miles, but I do it at 5K. Cheap insurance, especially if you change it yourself.

Every 6 months if you are being good, every 12 months if you are being ok. Anything over 12 months you don't deserve to have a 911

The milage doesn't count that much unless you are doing big milages. Short trips and not much driving is even worse for your oil as it can contain moisture in solution and never gets to burn it off. The water gets there from condensation.

Also change your gearbox oil at least once every two years - again cheap insurance.

The above info is just my opinion.

I'm kind of strange. When nothing needs fixing on my car I change the oil just for something to do.

Recently that hasn't been too often :-( About every 3,500 miles

I have an '87 Carrera and have not changed my oil since I got it 3000 miles ago in late July. It was serviced just before I bought it. It burns a little oil and there is a slight leak on the lower left cam cover. I have to add a quart every 1000 miles, which concerns me. But I don't know how much of it is leaking out, as it only leaks when I'm driving, and only then onto the heat exchanger, which burns it off. Since I've already added 3 qts., I figure the oil in there stays relatively fresh. Though I look forward to changing it after a few thousand more miles. I usually don't drive it during the week. But I drive it hard and far on the weekends.
