Consuming a quart of oil every 2000 miles is 100% normal…There is no design flaw and no problem…Some cars manage to burn less than that. That does not mean there is something wrong with your car…
A small amount of oil MUST escape the oil rings otherwise the compression rings would get no lubrication…If your owners manual allows the use of 10-30 grade oil in the summer months, you could switch to that, but if 0-20 is the only grade recommended then stick with it to protect your warranty…
