Hello all,

I would like to bring up oil consumption again. My car is guzzling 1 qt. approx.

750 miles. I have 10500 miles and it has been doing this since I purchased the car

new in 2003. I change the oil & filter every 5000 miles and only use Mobil 1 0/40.

I followed the 2000 mile break-in rule. (which was hard)

The next step is taking it to the dealer. Any clue? Is this normal?

What will they do? :eek:

Any leak underneathe? Get the car up on ramps to check bc leak doesn't always drip to floor. Compression test should be done if no leak.

Try to keep the oil in there for 10k mi. Sometimes new engine have a hard time breaking in w oil that's too new.

Try thicker oil, esp in summer, 15-50 wt Mobil 1.

No leaks, I clean the under-carriage while changing the oil.

Someone else mentioned that the synthetic oil slows the wear-in time.

My 930 used a qt. approx. every 1500 miles. (but that car had over 500hp)

My Cayenne never needs oil between changes.

My experience on a 2004 40th anniversary 911 is as follows:

Changed the factory Mobil 1 0W40 at 1000 miles. Have had 2 changes since then with Mobil 1 15W50. Oil consumption seemed a little high until we just hit the 3000 mile mark - then it (oil consumption) basically stopped - or has settled down dramatically. Followed the break in procedure faithfully as well. Our car has the X51 power kit - and in the Porsche TSB, it stated that the engine does not develop full horsepower until it reaches approximately 6500 miles. This suggests these engines - X51 power kit or not - are fairly tight for some time, which means long lasting if they are looked after.

You probably won't get a true indication of oil consumption until you get to around 10,000 miles. At that point, one quart per 1000 miles is within factory guidelines anyway.......

As long as you are not getting blue smoke - all should be fine.

When you have have high oil consuption and no external leaks, it's a good idea to check the plugs. If some of them are crusted with oil deposits, it could be the valve seals...
