So the quick version: When I got my 2011 CPO 335, I ordered it with the PPK. They figured out half way through that they couldn't install without the oil cooler - so they, very nicely, installed an oil cooler for me, and everything was fine.

Shortly after, the oil light turned on. I brought it in, and it was a quart low. They topped it off after checking for leaks, and everyone assumed that it was just settling that occurred, and the oil cooler raised the capacity by about a quart.

2000 miles later, its a quart low again. I called into service, and they told me they will check it out again, but that BMW considers in within tolerance to burn a quart every 750 miles.

Has anyone else run into this? My 328 would run 25k miles without going a quart low, this seems extreme, and burning a quart every 750 miles seems ludicrous...

The problem is that I haven't had this car that long, so no idea if its always burned oil like this before.

Actually sorry - as I look around I realize that 335's and oil loss is a widely reported issue and probably nothing to do with the PPK install.

It is normal to burn some oil! Probebly more normal then not burning any oil...

Well sure - 'some' is a wonderfully non-specific number. I would consider a half a quart per 1k miles or more to be more then some. my 328 didn't burn anything noticeable - my oil changes were over 20k miles per, and it never needed oil added.

That is a bit high... A turbocharged car does burn more oil! But yours is burning to much...
