Can anyone provide a general consumption rate for their 997.1 TT? This is my first Porsche and wanted to see if everything was about right. I have had the occasional smoke at start up (2 times over about 5K miles) at least that I noticed. No CELs or warnings; I feel as though I drive the car rather spirited on a daily basis, but not abusive (unfortunately, no track time). The car is under CPO so I would rather replace everything if there is an issue, but my OCD is starting to kick in and I am wanting to make sure nothing is wrong.

Over the last 1K, I have used about 1QT.

 

Mine uses about 1/2 a quart every 2000 miles.

 

I forgot to mention that mine is bone stock, but that is about the same as mine since I just added the other half of the quart last night getting gas at about 2K miles and not burning the whole quart over 2K. Thanks for the reassurance.

 

Mine takes about a quart every 9,000m - which is what I drive per year - no ball busting please, this is a weekend car . I see a wee bit of smoke on startup every 4th start roughly.

 

you guys arent driving your cars i take it.
1k miles per quart is what Porsche says is "acceptable" according to the owners manual.

 

by the way, i now use 5w40 redline motor oil (very very good oil, not available in stores though).on my car.

there is a very noticeable difference in consumption now.
