Last week I have given our VW Polo 1.2 TDI 1 year service @ Uppal - Hyderabad. They have charged 4.3 litres for Engine oil. To my surprise VENTO 1.6 TDI which was serviced on same day was charged 4.3 litres. Its quite annoying experience to me that 1.2 TDI and 1.6 TDI engines consume same amount of oil. Had anyone observed this before ??
