So it seems like I am literally adding a bottle of oil to the turbo every 300 or 400 miles. I know this is below Porsche recommendation of 650-1000 miles. Does it make sense for it to be that low since I really run the car hard? I just want to make sure that something isn't messed up.

 

I would check it out at the dealer. I burn roughly 1/2 qt. every 5000 miles. There seems to be quite a variation with oil consumption with these cars. If it's really as much as you say, I would get the dealer to do something about it. It's an '06 foir crying out loud and that would be unacceptible to me....

 

I keep on adding about 2 litres of oil every 3000KM but if i drive hard that number can go down to every 2000KM and thats on a 2005 Cayenne Turbo... It's an Oil Guzzler alright, but you gotta love it
