re: Cayenne oil consumption

[SPIRO]

So, I have this problem. Ever since buying a Boxster last year, I now want all our vehiclesto be high performance.

So my wife and I test drove a 2009 Cayenne GTS yesterday. The salesman told us that the Cayenne GTS will burn approximately 1 quart of oil every 600 miles or so. He stated this related to "reducing emissions". Now, intuitively, it would seem that the more oil burned/leaking through pistons and valves, the worse emissions should be.

I am wondering, is this amount of oil consumption true in the real world? Mechanically, where does all this oil go?

That sounds like a line of BS to me, I know the turbos can use oil but that amount seems like a lot. Never heard that burning oil can reduce emissions.

[SPIRO]

I agree, a normally aspirated NEW Cayenne should not, in my opinion, burn that amount of oil. And he had no information to back up his statement regarding emissions.

I know the 1qt/600 miles is standard spec for the flat sixes, but didn't realize it was also the same for the V6-V8 Cayennes (normally aspirated). I only added 0.5qt of oil to my Boxster after the first 200 miles, and have never added oil since.

I agree with wvicary -- you were told BS and I also don't understand why burning oil helps to reduce emissions. Euro oil companies are coming out with low-SAPS (sulfated ash, phosphorous, sulfur) oils to reduce emissions from burning oil and extending the catalytic convertor life. I think the salesperson is confused with the specs.

I've got an '08 Cayenne S. It came with 2 quarts of Mobil 1 0W40 from the dealer. They said when those were gone to come back for more. Service guys told me some engines drink lots of oil. I didn't add any oil until well after 4K miles.

From reading Cayenne sections on some of the other online Porsche forums, some Cayenne V-8 engines do use at least a quart every 600-800 miles. Others don't. Maybe it's the luck of the draw. I don't think it's to reduce emissions.

Do you really want an SUV that's faster than your Boxster? We've also got an '01 Boxster and '05 Carrera. You will like the Cayenne if you enjoy your Boxster :)

I'm really happy with the Boxster . It's my wife who wants the faster SUV. She is truly a great driver, and drives even more aggressively that I do. We have these great , scenic twisty roads in Kentucky that are a lot more fun in a true driver's vehicle.

I find it odd, that with well made German engines, with Porsche's tight specifications, that some engines would burn a lot more oil than others. I guess the salesman is setting us up with the worst case scenario.

The early S never burnt any oil, the TT always did, about a quart per 1000 in the worst case. It now seems to be the norm on 08s and beyond. So I guess we are supposed to be getting a little more MPG but offsetting that by increasing oil consumption AND increasing world hunger by using synthetic oil

Yes I am confused

Hi, I have a 08 Cayenne S. the oil consumption issue is printed in the owners manual. At 1500 miles my check oil light came on and I had to put in about a little over 2 quarts to bring it to full. I have the dealer look at the car at their free inspection. They said it was within normal specifiacations. Now I'm at 8K mileas and I have not had to top of the oil at all since the first incident. They also told me not to add any oil until the low oil light comes on. I don't know about the emissions.

Hi Spiro,

I have a 2008 Cayenne S and I suprised my self the first time the oil light came on.

Driving a bit aggressively I add a quart about every 1000 miles i do.

Hope this helps.

So I guess the 04 was good for something then, I have 70K plus miles and only once at 2k put any oil in between services.
