Engine oil question

[sim085]

Hello, I have a Vitz from 2007 with 1.3 Engine and automatic transmission. I do not know if this is a problem or normal for the car.

Last March when I curved the oil light turned on. I checked with the stick and found that the oil was very low. I had taken the car for a service (which included an oil change) a couple of months before so I took the car to a mechanic because I thought it was leaking. The mechanic told me that these vars (Vitz 2007) were known to burn oil and he topped the oil again.

Now, August, after around some 5000KM the oil light turned on again when I curved. I checked the oil using the stick and found that again it was very low. I have now topped it again.

However I was wondering - is this really normal?
