Oil change intervals?

[Kochman]

If you are just putzing around town with it then you should be able to get away with 7500-10000. However, if you are taking it to the track or pushing it alot, then 5000.

There are schools-of-thought that suggest oil changes prior to 5,000 miles can actually increase wear.

HUH? I've never heard this one. I'd like to hear the reasoning behind it.

Ohh, and for me. 7500, or once a year, what ever is first.

No M1 for me, not even in my beater. There are better oils for less money or equal dollars out there. Elf/Total for the Porsche.

Benny, this has been discussed many times on this Forum (and others). Your "search" feature will be your best friend.

It is now up to 20,000 miles with the first generation 987. This is called extended drain intervals. You can read about it here. Other car companies are doing this as well.

I am from the old school where it was about 6,000 miles. But I go over it. Engines have improved over the years. Other cars hold about 4 to 5 quarts and use normal oil. The Boxster holds almost 10 quarts and uses synthetic. So I go it out of my mind and change the oil every 15,000 miles, if it needs it or not. I do not do anything fancy with the car - it is my daily driver and only car.

I have a 1997 that I have owned for 9 years with 67,000 miles.

Benny,

Here's one place that supports the non-3000 mile oil change: http://neptune.spacebears.com/cars/stories/oil-life.html

I also don't use M1, but not for any technical reasons -- I run Motul 8100 Xcess 5W-40 -- when the car's out of warranty, I may go with Redline as bmussatti
does.

Regards,
paul...
