I listened to a smoking tire interview with Steve Dinan. He said that the M3 has harder piston rings that are thinner so that it expands at high rpm's. If you don't visit the high rpm's on a regular basis... The piston rings stiffen up more and oil starts flowing past them.
For example I used to commute 100 miles round trip, freeway, steady speeds to save gas... And I was having to add a quart every 1500 to 2000 miles.
Now that I have a multinodal folding bike/ train commute... The m3 is used for fun on the weekends which means I'm not concerned with saving gas so as soon as the engine is warmed up I let it rip to 8,000 regularly... So far almost 2,000 miles and I'm only down 1/2 a quart.
Still... If you're burning 1qt every 500 miles you need to find where the leak is... That's excessive
