Sajeev,

First I wanted to let you know that nearly everyday on my lunch break I check TTAC and each time I see a Piston Slap article I always make sure to read through it.  I admire your knowledge and have learned quite a bit from your articles. I guess that I have a two part question.

The first part being since when has it become “acceptable” that a modern (low mileage) engine can consume a quart of oil in less than 5K miles.  Audi and VW jump the front on my mind with their 2.0T mills, but I hear more and more through the woodwork about engines drinking oil.  The second part of my question probably has more to do with correlation than causation but it seems like direct injection plays a role in this IMO unacceptable oil consumption.

Thanks!
