Engines burn oil period. Doesn't matter who makes them. Besides, ever heard of a little known car called the S2000? Even Honda acknowledges that this car burns a lot of oil and notifies its owners that this is normal for the car.

Anyway, yeah burning a quart of oil every 700 miles is way too much. Don't you guys use liters up there though? That's the thing about warranties. You have to fight hard to get it to actually work for you. My friend bought the lifetime no matter what we will replace warranty on her tires from America's Tires and after less than a year the tire has uneven wear. It's a completely stock GSR. But they refuse to replace claiming bad alignment, or blah blah.
