It's really difficult to pinpoint the exact cause. Unless we are to disassemble and compare two engines - a non-oil consuming one and one which consumes , say 500ml every 5000km. Only then can we establish a correct reason. Being 2012, i believe the engines leave the factory in a similar spec and tolerances. And we only need a bare minimum amount of running it in till we can really thrash the engines as we feel like. It is during this running in window that some users completely baby the engine. It is a proven fact that babying the new engine leads to improper seating of the rings in the cylinder. The rings never seal as completely as they could have and hence you experience some amount of regular oil consumption. I am not stating that the owners are responsible for oil consumption in their cars but putting some food for thought out here. It is not possible to pinpoint the cause of each and every engine. The companies know that the engines will be at the mercy of varied drivers and driving conditions- so they simply put in a clause saying X amount of oil consumption is normal. And as you can see already , a few have reported some consumption in this thread and others are saying no consumption. I'm also in the no consumption group. But yes, oil consumption in our family budget(relatively) cars is not excusable. It can be excused in a car like, say, BMW M3 ( the M3 DOES eat oil) , but not in the Punto or Linea. Cheers.
