I have read lots of posts about burning oil in the Cayenne. I am at 9,000 miles since the previous change, and just looked at the level on the dipstick and it is near max, where it was upon filling.

Have I just gotten very lucky that it doesn't burn any noticeable amount of oil? Not that I'm complaining I just was expecting to see less oil when I checked it.

 

My "normal" consumption when comparing oil level at oil change against future oil measurements (oil AND normal accumulations of moisture and unburned fuel) appears to be near zero. That was mostly a highway 5000 mile trip. So I am certain that some oil is being consumed because I am certain that small amounts of moisture and unburned fuel are being captured in the oil....as designed. So my point for you to consider is that when performing comparisons, consider the added moisture and unburned fuel AND always try to measure with the oil at about the same temps, same parking spot and same amount of time after shutdown.

When I tow a trailer at 70mph and in the mountains over a 600 mile trip I will see a one bar drop. I don't have a dipstick. I don't see higher oil temps.

I have about 12,000 miles on this car which I purchased with 37,000 miles. So I have some data, but not alot...yet

 

I think the Turbos are the ones that tend to burn more oil. Which isn't really unusual for some Turbo cars.

 

My '06 consumes no oil. Zilch. Nada. The level never changes on the dipstick.

 

So far my 2015 S uses no oil at 2500 mi. I run it like I stole it all the time.

 

TTs are thirsty in more ways than one. My '08 TT consumes about a quart every 800-1000 miles. Porsche states that 1L per 600 miles is normal.

How often do you change your oil & filter? My 4.5 L doesn't burn any oil that I notice.

 

Mine burns about a gallon every 30 miles.

 

I only put about 4000 miles a year so I change once a year just before winter.

 

Nope. Never add oil to my '06S.

 

I get about 1500mi/qt. It's been the same as long as I've owned it. 04tt 150k on the odo.

 

I use about a liter every 1200-1400km and i note most 'S' owners report no oil usage. I'm pretty sure the turbos are sitting there drinking the stuff.

 

Yep my TT drinks a quart every 500 miles and the S burns a quart every 10k

 

I change oil every 12000km, and I have never add any oil between oil changes.
