Should I change my oil at 2,000 miles?

I've read a couple posts in the 987 forum at 6speedonline.com, and some people have mentioned that its a good idea to change the oil on your Cayman after the 2k mile break-in.

I know that oil changes should be yearly, but...Has anyone here changed their oil at 2k, or recommend for/against it?

This has been discussed numerous times.

I suggest you try searching for oil change.

virtually everyone has a different opinion on the "1st oil change " question but my opinion is that is that you do not have to change it that quickly .

I changed oil at about 2k miles (just after break-in and just before the first track event). I don't know if it's really necessary, but it made me feel more comfortable, so I know it was right for me. I also changed at about 9-10k and again at about 17k.

Waste of good oil really. A number of members here have changed their oil at 10,000 miles and sent a sample to Blackstone labs for analysis. Each time the report comes back the same. It typically indicates that the oil contains a lot of assembly contaminants but is otherwise in good condition.

See this thread: http://www.caymanclub.net/cayman-tec...10k-miles.html

I think 2,000 miles is complete overkill. Maybe 10,000 miles, if you really work the motor hard. Even then, it's likely to be unnecessary. I will probably drop my oil at 10K and have it analyzed. The results of that analysis will determine my intervals going forward.

Remember, there is a downside to changing it too soon beyond the obvious waste of money. Changing oil unnecessarily also strains the environment and increases our dependence on oil. Use your oil wisely, for all of our sakes.

Getting assembly contaminants flushed out of the motor doesn't seem like a bad thing.

A spectrometric oil analysis isn't really analyzing the oil, it measures the amount and type of metals to help identify excessive wear and impending failure. The best way to use oil samples is to do them at regular intervals to look for trends. It's not really an indicator of the quality of the oil itself or an aid to determine oil change intervals.

Good info, I'll wait til 10k. Thanks.

I have noticed that my oil level has dropped to between 1/2-3/4...so I should at least top-off the oil, right?

Yes, but don't get too eager on that either. Each line in the display represents 0.4 liters and it's not uncommon for the reading to fluctuate by 1 or even 2 bars based on condensation and temperature. I say, if you see it down and stay down for 4 or 5 readings, then add a little. But don't pull over as soon as you see it go down a click because mine has done that several times only to come back up all by itself. Also keep in mind 0.4 liters down out of 7.75 liters of total capacity is about 5%.

Right. I noticed that it had dropped after a trip to Santa Barbara this weekend, but that it raised back up the morning after I got home. Again, thanks for the info, and I'll keep an eye on it.

Absolutely correct.

People also worry far too much about the "metal" content in the first batch of oil as being a bad thing. What they don't realize is that often this is necessary for proper ring, cylinder wall, and bearing break-in. There have been several cases in manufactures history (Porsche included) where changing out the first batch of oil too soon has been a bad idea.

Take the first VW VR6 engines back in the early mid 90's. VW didn't want you to change the first oil too soon. Those that did could encounter problems such as lower compression and higher oil consumption down the road,......all due to rings/cylinder walls not being broken-in and "burnished" correctly. Porsche's last 928 engine (5.4L GTS) had a serious tendancy to drink oil at a rate of 1 quart per 1k miles if not broken in properly, which meant leaving the factory fill in it for a while. At the insistance of owners, many GTS engines were pulled and replaced by Porshce for excessive oil consumption. Much of this was due to owners changing 9 quarts of oil every couple thousand miles. Just not necessary, and not "better" for the engine. Anything harmful to the engine will be gotten by the filter, and we now have solid proof that all the other qualities of the oil are just fine for many thousands of miles, so lets be sensible and responsible at the same time.
