997 Oil Consumption

[paulg1]

Porsche Service Manager tells me that history with 997 is showing that about every 1500 miles requires addition of 1 quart of oil. I have 3850 miles and electronic oil gauge shows full. Have added no oil since oil change at approx. 1000 miles. Has anyone experienced the same? Is there history of electronic gauge being faulty? Thanks

Your dealer is wrong - first the 997 engine is the same engine as the 996 - some cars can use a quart every 1500 miles and some do not. For instance my MY99 does not use any oil between changes at all. If your car does not use oil then simply smile at those folks that complain about using a quart every 1500 miles. :D

My friends and I are seeing the same thing, we're adding 1 quart of oil somewhere between delivery miles and 3500 miles and after the rings set in fully it doesn't burn any more oil. This seems to be the case with both the 3.6 liter and the 3.8 liter. I just added a quart to mine today at 2950 miles. We'll see if it wants any more but from what people are saying probably not.

Loren,

I just bought a 2007 CS I only have 500 miles on it. When is my first oil change due and how often should I be checking my oil level

I have about 12000 miles now and average 1 quart every 4000 miles now, Did my own oil change at 7000 miles and plan on every 7K or so! I have an 06 2S.

1stporsche - Check the manual, but if I remember correctly it says at 24,000km (15,000 miles) or once a year, whatever comes 1st.

My 2005 C2S burnt a quart within the first three months but hasn't used enough for a top up since. But then I only drive it 9,000km (5,600 miles) a year...

Actually porsche says 1 year or 20,000 miles! Check oil before each startup, when cold just takes 5 seconds!!

I turned 12,000 miles on my 997 C2S today, and haven't added a quart of oil since I drove it off the lot. Delivery miles were under 10.

Contrary to what many feel, I believe that breakin does make a difference. My 996 had 150+ miles on it when I took delivery, and it used a quart of oil every 1,500 miles until I sold it with about 40,000 miles on it. My 986 had around 15 miles at delivery, and I added one quart of oil in 70,000 miles.

Both of the cars delivered with "new" mileage didn't use oil. The car delivered with 100+ miles used oil. The story from the salesman on the car with 100+ miles is that he drove it home a few times, but outside of that it hadn't been driven. I believe that it had been test driven and abused during the first 100 miles. The cars delivered with "new" mileage were driven in accordance with the instructions in the user's manual.

Make your own decision, but I know what I believe.

Hi,

Suggest you floor it once and awhile. This is a racing motor

and it needs to breath.

I use 1 quart every 1000 miles. I broke it in per factory guidance. Am at 14,000 miles today. It has used oil at that rate from the beginning.
