I don't think it's normal for ANY car to burn that much oil. That sounds ridiculous. IMHO!!

did they add oil to the filter before they installed the new one. you don't have to but if you don't you will run short a little oil and need to add some. Therefore if they didn't add oil to the filter some of it is now sitting in the filter.

the technician I spoke to about oil consumption stated that, "it is normal to burn maybe a quart b/w oil changes within the first few thousand miles", but that it should really slow down after that. 1.5 qts is a lot of oil for an engine to consume.

My STi used 1 quart every 3k miles for a while. It would also use a quart every track day until recently. I have started running it a lot harder and feel like the engine is the strongest it has ever run. It has not used/burned oil now for the last two oil changes and track days. The car now has 15k miles on it and the oil has been changed 6 times. It appears to me that it took 10k + for the engine to fully break in. I also have experienced better mileage over this time as well.

-Good luck

Edit: I use redline synthetic oil btw.

may be your engine not break in properly? the piston rings didn't seal well and it burns oil?
too early switch to synthetic oil will cause burning oil as well...

my wrx used between 1-1.5qts between changes, and so does my STi, which is at 7k miles.

I drove my WRX hard, and I drive my STi hard as well.

I will switch to REDLINE 15W-50 at my next change, and will switch to REDLINE 10W40 for the winter months.
